We appreciate the contributions of security researchers and developers in helping us identify and address potential vulnerabilities. ## Reporting a Vulnerability If you discover a potential security vulnerability in R2R, please follow these steps to report it: 1. Create a new issue on the GitHub repository using the "Vulnerability Disclosure" issue template. 2. Set the issue as "confidential" if you are unsure whether the issue is a potential vulnerability or not. It is easier to make a confidential issue public than to remediate an issue that should have been confidential. 3. Label the issue with the `security` label at a minimum. Additional labels may be applied by the security team and other project maintainers to assist with the triage process. 4. Provide a detailed description of the vulnerability, including steps to reproduce, potential impact, and any other relevant information. 5. If the issue contains sensitive information or user-specific data, such as private repository contents, assign the `keep confidential` label to the issue. If possible, avoid including such information directly in the issue and instead provide links to resources that are only accessible to the project maintainers. ## Vulnerability Handling Process Once a vulnerability is reported, the R2R security team will follow these steps: 1. Acknowledge receipt of the vulnerability report within 48 hours. 2. Assess the severity and impact of the vulnerability. 3. Develop a fix or mitigation plan for the vulnerability. 4. Notify the reporter about the progress and estimated timeline for the fix. 5. Once the fix is ready, release a new version of R2R that addresses the vulnerability. 6. Publicly disclose the vulnerability and the fix after a reasonable period to allow users to update their installations. ## Scope This security policy applies to the R2R codebase and its dependencies. It does not cover vulnerabilities in the underlying operating systems, hardware, or third-party libraries used by R2R. ## Recognition We greatly appreciate the efforts of security researchers and developers who responsibly disclose vulnerabilities to us. With your permission, we will acknowledge your contribution in the release notes and any public disclosures related to the vulnerability. ## Contact If you have any questions or concerns regarding the security of R2R, please contact the project maintainers at [security@r2r.com](mailto:security@r2r.com). Thank you for helping us keep R2R and its users secure! ================================================ FILE: deployment/k8s/kustomizations/helm-values_hatchet.yaml ================================================ # sharedConfig is inherited by all backend services: api, grpc, controllers, scheduler sharedConfig: # you can disable shared config by setting this to false enabled: true # these are the most commonly configured values serverUrl: "http://localhost:8080" serverAuthCookieDomain: "localhost:8080" # the domain for the auth cookie serverAuthCookieInsecure: "t" # allows cookies to be set over http serverAuthSetEmailVerified: "t" # automatically sets email_verified to true for all users serverAuthBasicAuthEnabled: "t" # allows login via basic auth (email/password) grpcBroadcastAddress: "localhost:7070" # the endpoint for the gRPC server, exposed via the `grpc` service grpcInsecure: "true" # allows gRPC to be served over http # defaultAdminEmail: "" # in exposed/production environments, change this to a valid email # defaultAdminPassword: "" # in exposed/production environments, change this to a secure password # you can set additional environment variables here, which will override any defaults env: {} api: enabled: true replicaCount: 2 image: repository: "ghcr.io/hatchet-dev/hatchet/hatchet-api" tag: "v0.54.7" pullPolicy: "Always" migrationJob: image: repository: "ghcr.io/hatchet-dev/hatchet/hatchet-migrate" serviceAccount: create: true name: hatchet-api envFrom: -

Agentic Retrieval-Augmented Generation (RAG) with a RESTful API. ## Documentation Sections ### [Introduction](./introduction/) - [System Overview](./introduction/system.md) - [Guides](./introduction/guides/) ### [Documentation](./documentation/) - [Getting Started](./documentation/README.md) - [General Features](./documentation/general/) - [Retrieval](./documentation/retrieval/) - [Advanced Features](./documentation/advanced/) ### [API & SDKs](./api/) - [API Reference](./api/) - [SDK Documentation](./api/) ### [Cookbooks](./cookbooks/) - [Data Processing](./cookbooks/data-processing/) - [System Operations](./cookbooks/system-operations/) ### [Self-Hosting](./self-hosting/) - [Installation](./self-hosting/getting-started/installation/) - [Configuration](./self-hosting/configuration/) - [Deployment](./self-hosting/deployment/) ================================================ FILE: docs/cookbooks/application.md ================================================ R2R offers an [open-source React+Next.js application](https://github.com/SciPhi-AI/R2R-Application) designed to give developers an administrative portal for their R2R deployment, and users an application to communicate with out of the box. ## Setup ### Install PNPM PNPM is a fast, disk space-efficient package manager. To install PNPM, visit the [official PNPM installation page](https://pnpm.io/installation) or follow these instructions: For Unix-based systems (Linux, macOS): ```zsh curl -fsSL https://get.pnpm.io/install.sh | sh - ``` For Windows: ```powershell iwr https://get.pnpm.io/install.ps1 -useb | iex ``` After installation, you may need to add PNPM to your system's PATH. ### Installing and Running the R2R Dashboard If you're running R2R with the Docker, you already have the R2R application running! Just navigate to [http://localhost:7273](http://localhost:7273). If you're running R2R outside of Docker, run the following commands to install the R2R Dashboard. 1. Clone the project repository and navigate to the project directory: ```zsh git clone https://github.com/SciPhi-AI/R2R.git cd R2R-Application ``` 2. Install the project dependencies: ```zsh pnpm install ``` 3. Build and start the application for production: ```zsh pnpm build pnpm start ``` The dashboard will be available at [http://localhost:3000](http://localhost:3000). ## Features ### Login To interact with R2R with the dashboard, you must first login. If it's your first time logging in, log in with the default credentials shown. By default, an R2R instance is hosted on port 7272. The login page will include this URL by default, but be sure to update the URL if your R2R instance is deployed elsewhere. For information about deploying a local R2R application server, see the [quickstart](/documentation/quickstart). ![R2R Dashboard Overview](./images/application/login.png) ### Documents The documents page provides an overview of uploaded documents and their metadata. You can upload new documents and update, download, or delete existing ones. Additionally, you can view information about each document, including the documents' chunks and previews of PDFs. ![Documents Page](./images/application/oss_dashboard_documents.png) ### Collections Collections allow users to create and share sets of documents. The collections page provides a place to manage your existing collections or create new collections. ![Collections Page](./images/application/oss_collections_page.png) ### Chat In the chat page, you can stream RAG responses with different models and configurable settings. You can interact with both the RAG Agent and RAG endpoints here. ![Chat Interface](./images/application/chat.png) ### Users Manage your users and gain insight into their interactions. ![Users Page](./images/application/users.png) ### Settings The settings page allows you to view the configuration of and edit the prompts associated with your R2R deployment. ![Settings Page](./images/application/settings_config.png) ![Settings Page](./images/application/settings_prompts.png) ## Development To develop the R2R dashboard: 1. Start the development server: ```zsh pnpm dev ``` 2. Run pre-commit checks (optional but recommended): ```zsh pnpm format pnpm lint ``` ================================================ FILE: docs/cookbooks/custom-tools.md ================================================ There are many cases where it is helpful to define custom tools for the RAG Agent. R2R allows for users to define custom tools, passing these definitions into the Agent at server start. ### Defining New Tools There is a directory in the R2R repository, `/docker/user_tools`, which is mounted to the R2R docker container. It is here that we will place our custom tool files. There, we will find a README.md file, which includes a template for our new tool: ```python from core.base.agent.tools.base import Tool class ToolNameTool(Tool): """ A user defined tool. """ def __init__(self): super().__init__( name="tool_name", description="A natural language tool description that is shown to the agent.", parameters={ "type": "object", "properties": { "input_parameter": { "type": "string", "description": "Define any input parameters by their name and type", }, }, "required": ["input_parameter"], }, results_function=self.execute, llm_format_function=None, ) async def execute(self, input_parameter: str, *args, **kwargs): """ Implementation of the tool. """ # Any custom tool logic can go here output_response = some_method(input_parameter) result = AggregateSearchResult( generic_tool_result=[web_response], ) # Add to results collector if context is provided if context and hasattr(context, "search_results_collector"): context.search_results_collector.add_aggregate_result(result) return result ``` This template has two basic methods: 1. `__init__` is where we define the tool. The description that we make here is shown to the agent. 2. `execute` is where we define any custom tool logic and interact with the inputs. ### Writing our new tool Below, we have an example of a toy tool, which takes an integer and string input, returning a silly message to the agent. Should your tool require additional dependencies, be sure to include them in the `user_requirements.txt` file located in the `/docker` directory. ```python from r2r import Tool, AggregateSearchResult class SecretMethodTool(Tool): """ A user defined tool. """ def __init__(self): super().__init__( name="secret_method", description="Performs a secret method.", parameters={ "type": "object", "properties": { "number": { "type": "string", "description": "An integer input for the secret method.", }, "string": { "type": "string", "description": "A string input for the secret method.", }, }, "required": ["number", "string"], }, results_function=self.execute, llm_format_function=None, ) async def execute(self, number: int, string: str, *args, **kwargs): """ Implementation of the tool. """ output_response = f"Your order for {number} dancing flamingos has been received. They will arrive by unicycle courier within 3-5 business dreams. Please prepare {string} for them." result = AggregateSearchResult( generic_tool_result=output_response, ) context = self.context # Add to results collector if context is provided if context and hasattr(context, "search_results_collector"): context.search_results_collector.add_aggregate_result(result) return result ``` Finally, we can modify our configuration file's `agent` section to include our new tool: ```toml [agent] rag_tools = ["secret_method"] ``` Finally, we can run the following and see that our agent called our new method, passed the required parameters, and understood its output: ```python client.retrieval.agent( message={"role": "user", "content": "Can you run the secret method tool? Feel free to use any parameters you want. I just want to see the output."}, ) ``` ```zsh results=AgentResponse(messages=[Message(role='assistant', content='The secret method tool produced the following output:\n\n"Your order for 42 dancing flamingos has been received. They will arrive by unicycle courier within 3-5 business dreams. Please prepare Hello, World! for them."\n\nThis whimsical response seems to be a playful and humorous output generated by the tool.', name=None, function_call=None, tool_calls=None, tool_call_id=None, metadata={'citations': [], 'tool_calls': [{'name': 'secret_method', 'args': '{"number":"42","string":"Hello, World!"}'}], 'aggregated_search_result': '[]'}, structured_content=None, image_url=None, image_data=None)], conversation_id='12ad2d6b-1429-48ea-9077-711726d8cfde') ``` ================================================ FILE: docs/cookbooks/email.md ================================================ Configuring your deployment to require email verification helps keep your deployment secure, prevents unauthorized account creation, reduces spam registrations, and ensures you have valid contact information for your users. Currently, R2R has integrations for both [Mailersend](https://www.mailersend.com/) and [Sendgrid](https://sendgrid.com/). ## Setup Both Mailersend and Sendgrid require registration, but do offer free tiers for evaluating their services. Create an account with your desired provider, and generate an API key. ### Mailersend - [Create an account](https://www.mailersend.com/signup) - [Generate an API key](https://www.mailersend.com/help/managing-api-tokens) ### Sendgrid - [Create an account](https://twilio.com/signup) - [Generate an API key](https://www.twilio.com/docs/sendgrid/ui/account-and-settings/api-keys) ## Creating a Template Once you have registered for an account with your email provider, you will want to create an email template. Providers will have pre-made templates, or you can build these from scratch. ![A Mailersend welcome template](./images/email/mailersend.png) Once you save a template, you will want to make note of the template id. These will go into the configuration files. ## Configuration Settings We can then configure our deployment with the templates, redirect URL (`frontend_url`), and from email. ### Configuration File ```toml title="mailersend.toml" [email] provider = "mailersend" verify_email_template_id="" reset_password_template_id="" password_changed_template_id="" frontend_url="" from_email="" ``` ```toml title="sendgrid.toml" [email] provider = "sendgrid" verify_email_template_id="" reset_password_template_id="" password_changed_template_id="" frontend_url="" from_email="" ``` ### Environment Variables It is required to set your provider API key in your environment: ```zsh export MAILERSEND_API_KEY=… export SENDGRID_API_KEY=… ``` ================================================ FILE: docs/cookbooks/evals.md ================================================ This guide demonstrates how to evaluate your R2R RAG outputs using the Ragas evaluation framework. In this tutorial, you will: - Prepare a sample dataset in R2R - Use R2R's `/rag` endpoint to perform Retrieval-Augmented Generation - Install and configure Ragas for evaluation - Evaluate the generated responses using multiple metrics - Analyze evaluation traces for deeper insights ## Setting Up Ragas for R2R Evaluation ### Installing Ragas First, install Ragas and its dependencies: ```python %pip install ragas langchain-openai -q ``` ### Configuring Ragas with OpenAI Ragas uses an LLM to perform evaluations. Set up an OpenAI model as the evaluator: ```python from langchain_openai import ChatOpenAI from ragas.llms import LangchainLLMWrapper # Make sure your OPENAI_API_KEY environment variable is set llm = ChatOpenAI(model="gpt-4o-mini") evaluator_llm = LangchainLLMWrapper(llm) # If you'll be using embeddings for certain metrics from langchain_openai import OpenAIEmbeddings from ragas.embeddings import LangchainEmbeddingsWrapper evaluator_embeddings = LangchainEmbeddingsWrapper(OpenAIEmbeddings()) ``` ## Sample Dataset and R2R RAG Implementation For this guide, we assume you have: 1. An initialized R2R client 2. A dataset about AI companies already ingested into R2R 3. Basic knowledge of R2R's RAG capabilities Here's a quick example of using R2R's `/rag` endpoint to generate an answer: ```python from r2r import R2RClient client = R2RClient() # Assuming R2R_API_KEY is set in your environment query = "What makes Meta AI's LLaMA models stand out?" search_settings = { "limit": 2, "graph_settings": {"enabled": False, "limit": 2}, } response = client.retrieval.rag( query=query, search_settings=search_settings ) print(response.results.generated_answer) ``` The output might look like: ``` Meta AI's LLaMA models stand out due to their open-source nature, which supports innovation and experimentation by making high-quality models accessible to researchers and developers [1]. This approach democratizes AI development, fostering collaboration across industries and enabling researchers without access to expensive resources to work with advanced AI models [2]. ``` ## Evaluating R2R with Ragas Ragas provides a comprehensive evaluation framework specifically designed for RAG systems. The R2R-Ragas integration makes it easy to assess the quality of your R2R implementation. ### Creating a Test Dataset First, prepare a set of test questions and reference answers: ```python questions = [ "Who are the major players in the large language model space?", "What is Microsoft's Azure AI platform known for?", "What kind of models does Cohere provide?", ] references = [ "The major players include OpenAI (GPT Series), Anthropic (Claude Series), Google DeepMind (Gemini Models), Meta AI (LLaMA Series), Microsoft Azure AI (integrating GPT Models), Amazon AWS (Bedrock with Claude and Jurassic), Cohere (business-focused models), and AI21 Labs (Jurassic Series).", "Microsoft's Azure AI platform is known for integrating OpenAI's GPT models, enabling businesses to use these models in a scalable and secure cloud environment.", "Cohere provides language models tailored for business use, excelling in tasks like search, summarization, and customer support.", ] ``` ### Collecting R2R Responses Generate responses using your R2R implementation: ```python r2r_responses = [] search_settings = { "limit": 2, "graph_settings": {"enabled": False, "limit": 2}, } for que in questions: response = client.retrieval.rag(query=que, search_settings=search_settings) r2r_responses.append(response) ``` ### The R2R-Ragas Integration Ragas includes a dedicated integration for R2R that handles the conversion of R2R's response format to Ragas's evaluation dataset format: ```python from ragas.integrations.r2r import transform_to_ragas_dataset # Convert R2R responses to Ragas format ragas_eval_dataset = transform_to_ragas_dataset( user_inputs=questions, r2r_responses=r2r_responses, references=references ) print(ragas_eval_dataset) # Output: EvaluationDataset(features=['user_input', 'retrieved_contexts', 'response', 'reference'], len=3) ``` The `transform_to_ragas_dataset` function extracts the necessary components from R2R responses, including: - The generated answer - The retrieved context chunks - Citation information ### Key Evaluation Metrics for R2R Ragas offers several metrics that are particularly useful for evaluating R2R implementations: ```python from ragas.metrics import AnswerRelevancy, ContextPrecision, Faithfulness from ragas import evaluate # Define the metrics to use ragas_metrics = [ AnswerRelevancy(llm=evaluator_llm), # How relevant is the answer to the query? ContextPrecision(llm=evaluator_llm), # How precisely were the right documents retrieved? Faithfulness(llm=evaluator_llm) # Does the answer stick to facts in the context? ] # Run the evaluation results = evaluate(dataset=ragas_eval_dataset, metrics=ragas_metrics) ``` Each metric provides valuable insights: - **Answer Relevancy**: Measures how well the R2R-generated response addresses the user's query - **Context Precision**: Evaluates if R2R's retrieval mechanism is bringing back the most relevant documents - **Faithfulness**: Checks if R2R's generated answers accurately reflect the information in the retrieved documents ### Interpreting Evaluation Results The evaluation results show detailed scores for each sample and metric: ```python # View results as a dataframe df = results.to_pandas() print(df) ``` Example output: ``` user_input retrieved_contexts response reference answer_relevancy context_precision faithfulness 0 Who are the major players... [In the rapidly advancing field of...] The major players in the large language... The major players include OpenAI... 1.000000 1.0 1.000000 1 What is Microsoft's Azure AI... [Microsoft's Azure AI platform is famous for...] Microsoft's Azure AI platform is known for... Microsoft's Azure AI platform is... 0.948908 1.0 0.833333 2 What kind of models does Cohere provide? [Cohere is well-known for its language models...] Cohere provides language models tailored for... Cohere provides language models... 0.903765 1.0 1.000000 ``` ### Advanced Visualization with Ragas App For a more interactive analysis, upload results to the Ragas app: ```python # Make sure RAGAS_APP_TOKEN is set in your environment results.upload() ``` This generates a shareable dashboard with: - Detailed scores per metric and sample - Visual comparisons across metrics - Trace information showing why scores were assigned - Suggestions for improvement You can examine: - Which queries R2R handled well - Where retrieval or generation could be improved - Patterns in your RAG system's performance ## Advanced Evaluation Features ### Non-LLM Metrics for Fast Evaluation In addition to LLM-based metrics, you can use non-LLM metrics for faster evaluations: ```python from ragas.metrics import BleuScore # Create a BLEU score metric bleu_metric = BleuScore() # Add it to your evaluation quick_metrics = [bleu_metric] quick_results = evaluate(dataset=ragas_eval_dataset, metrics=quick_metrics) ``` ### Custom Evaluation Criteria with AspectCritic For tailored evaluations specific to your use case, AspectCritic allows you to define custom evaluation criteria: ```python from ragas.metrics import AspectCritic # Define a custom evaluation aspect custom_metric = AspectCritic( name="factual_accuracy", llm=evaluator_llm, definition="Verify if the answer accurately states company names, model names, and specific capabilities without any factual errors." ) # Evaluate with your custom criteria custom_results = evaluate(dataset=ragas_eval_dataset, metrics=[custom_metric]) ``` ### Training Your Own Metric If you want to fine-tune metrics to your specific requirements: 1. Use the Ragas app to annotate evaluation results 2. Download the annotations as JSON 3. Train your custom metric: ```python from ragas.config import InstructionConfig, DemonstrationConfig demo_config = DemonstrationConfig(embedding=evaluator_embeddings) inst_config = InstructionConfig(llm=evaluator_llm) # Train your metric with your annotations metric.train( path="your-annotations.json", demonstration_config=demo_config, instruction_config=inst_config ) ``` ## Conclusion This guide demonstrated how to use Ragas to thoroughly evaluate your R2R RAG implementation. By leveraging these evaluation tools, you can: 1. Measure the quality of your R2R system across multiple dimensions 2. Identify specific areas for improvement in retrieval and generation 3. Track performance improvements as you refine your implementation 4. Establish benchmarks for consistent quality Through regular evaluation with Ragas, you can optimize your R2R configuration to deliver the most accurate, relevant, and helpful responses to your users.

The process works in several key stages: - Documents are first ingested and entities/relationships are extracted - Collections serve as containers for documents and their corresponding graphs - Extracted information is pulled into the collection's graph - Communities can be built to identify higher-level concepts - The resulting graph enhances search with relationship-aware queries Collections in R2R are flexible containers that support multiple documents and provide features for access control and graph management. A document can belong to multiple collections, allowing for different organizational schemes and sharing patterns. The resulting knowledge graphs improve search accuracy by understanding relationships between concepts rather than just performing traditional document search. ### Ingestion and Extraction Before we can extract entities and relationships from a document, we must ingest a file. After we've successfully ingested a file, we can `extract` the entities and relationships from document. In the following script, we fetch *The Gift of the Magi* by O. Henry and ingest it our R2R server. We then begin the extraction process, which may take a few minutes to run. ```python import requests from r2r import R2RClient import tempfile import os # Set up the client client = R2RClient("http://localhost:7272") # Fetch the text file url = "https://www.gutenberg.org/cache/epub/7256/pg7256.txt" response = requests.get(url) # Create a temporary file temp_dir = tempfile.gettempdir() temp_file_path = os.path.join(temp_dir, "gift_of_the_magi.txt") with open(temp_file_path, 'w') as temp_file: temp_file.write(response.text) # Ingest the file ingest_response = client.documents.create(file_path=temp_file_path) document_id = ingest_response["results"]["document_id"] # Extract entities and relationships extract_response = client.documents.extract(document_id) # View extracted knowledge entities = client.documents.list_entities(document_id) relationships = client.documents.list_relationships(document_id) # Clean up the temporary file os.unlink(temp_file_path) ``` As this script runs, we see indications of successful ingestion and extraction. Successful ingestion and extraction in the R2R dashboard. Viewing the entity in the dashboard. ### Deduplication If you would like to deduplicate the extracted entities, you can run the following method. To learn more about deduplication, view our [deduplication documentation here](/documentation/deduplication). ```python from r2r import R2RClient # Set up the client client = R2RClient("http://localhost:7272") client.documents.deduplicate("20e29a97-c53c-506d-b89c-1f5346befc58") ``` While the exact number of extracted entities and relationships will differ across models, this particular document produces approximately 120 entities, with only 20 distinct entities. ### Managing Collections Graphs are built within a collection, allowing for us to add many documents to a graph, and to share our graphs with other users. When we ingested the file above, it was added into our default collection. Each collection has a description which is used in the graph creation process. This can be set by the user, or generated using an LLM. ```python from r2r import R2RClient # Set up the client client = R2RClient("http://localhost:7272") # Update the description of the default collection collection_id = "122fdf6a-e116-546b-a8f6-e4cb2e2c0a09" update_result = client.collections.update( id=collection_id, generate_description=True, # LLM generated ) ``` The resulting description. ### Pulling Extractions into the Graph Our graph will not contain the extractions from our documents until we `pull` them into the graph. This gives developers more granular control over the creation and management of graphs. Recall that we already extracted the entities and relationships for the graph; this means that we can `pull` a document into many graphs without having to rerun the extraction process. ```python from r2r import R2RClient # Set up the client client = R2RClient("http://localhost:7272") # Pull the extractions from all docments into the default collection collection_id = "122fdf6a-e116-546b-a8f6-e4cb2e2c0a09" client.graphs.pull( collection_id=collection_id ) ``` As soon as we `pull` the extractions into the graph, we can begin using the graph in our searches. We can confirm that the entities and relationships were pulled into the collection, as well. Successful ingestion and extraction in the R2R dashboard. Entity distribution chart. ### Building Communities To further enhance our graph we can build communities, which clusters over the entities and relationships inside our graph. This allows us to capture higher-level concepts that exist within our data. ```python from r2r import R2RClient # Set up the client client = R2RClient("http://localhost:7272") # Build the communities for the default collection collection_id = "122fdf6a-e116-546b-a8f6-e4cb2e2c0a09" client.graphs.build( collection_id=collection_id ) ``` We can see that the resulting communities capture overall themes and concepts within the story. The communities generated for the collection. ### Graph Search Now that we have built our graph we can query over it. Good questions for graphs might require deep understanding of relationships and ideas that span across multiple documents. ```python from r2r import R2RClient # Set up the client client = R2RClient("http://localhost:7272") results = client.retrieval.search(""" What items did Della and Jim each originally own, what did they do with those items, and what did they ultimately give each other? """, search_settings={ "graph_settings": {"enabled": True}, } ) ``` Performing a searhc over the graph. ================================================ FILE: docs/cookbooks/ingestion.md ================================================ R2R provides a powerful and flexible ingestion to process and manage various types of documents. It supports a wide range of file formats—text, documents, PDFs, images, audio, and even video—and transforms them into searchable, analyzable content. The ingestion process includes parsing, chunking, embedding, and optionally extracting entities and relationships for knowledge graph construction. This cookbook will guide you through: - Ingesting files, raw text, or pre-processed chunks - Choosing an ingestion mode (`fast`, `hi-res`, `ocr`, or `custom`) - Updating and deleting documents and chunks For more on configuring ingestion, see the [Ingestion Configuration Overview](/self-hosting/configuration/ingestion). ### Supported File Types R2R supports ingestion of the following document types: | Category | File types | |-------------------|-------------------------------------------| | Image | `.bmp`, `.heic`, `.jpeg`, `.png`, `.tiff` | | MP3 | `.mp3` | | PDF | `.pdf` | | CSV | `.csv` | | E-mail | `.eml`, `.msg`, `.p7s` | | EPUB | `.epub` | | Excel | `.xls`, `.xlsx` | | HTML | `.html` | | Markdown | `.md` | | Org Mode | `.org` | | Open Office | `.odt` | | Plain text | `.txt` | | PowerPoint | `.ppt`, `.pptx` | | reStructured Text | `.rst` | | Rich Text | `.rtf` | | TSV | `.tsv` | | Word | `.doc`, `.docx` | | Code | `.py`, `.js`, `.ts`, `.css` | ## Ingestion Modes R2R offers four primary ingestion modes to tailor the process to your requirements: - **`fast`**: A speed-oriented ingestion mode that prioritizes rapid processing with minimal enrichment. Summaries and some advanced parsing are skipped, making this ideal for quickly processing large volumes of documents. - **`hi-res`**: A comprehensive, high-quality ingestion mode that may leverage multimodal foundation models (visual language models) for parsing complex documents and PDFs, even integrating image-based content. - On a **lite** deployment, R2R uses its built-in (`r2r`) parser. - On a **full** deployment, it can use `unstructured_local` or `unstructured_api` for more robust parsing and advanced features. Choose `hi-res` mode if you need the highest quality extraction, including image-to-text analysis and richer semantic segmentation. - **`ocr`**: OCR mode utilizes optical character recognition models to convert PDFs to markdown. Currently, this mode requires use of Mistral OCR. - **`custom`**: For advanced users who require fine-grained control. In `custom` mode, you provide a full `ingestion_config` dict or object to specify every detail: parser options, chunking strategy, character limits, and more. **Example Usage:** ```python file_path = 'path/to/file.txt' metadata = {'key1': 'value1'} # hi-res mode for thorough extraction client.documents.create( file_path=file_path, metadata=metadata, ingestion_mode="hi-res" ) # fast mode for quick processing client.documents.create( file_path=file_path, ingestion_mode="fast" ) # custom mode for full control client.documents.create( file_path=file_path, ingestion_mode="custom", ingestion_config={ "provider": "unstructured_local", "strategy": "auto", "chunking_strategy": "by_title", "new_after_n_chars": 256, "max_characters": 512, "combine_under_n_chars": 64, "overlap": 100, } ) ``` ## Ingesting Documents A `Document` represents ingested content in R2R. When you ingest a file, text, or chunks: 1. The file (or text) is parsed into text. 2. Text is chunked into manageable units. 3. Embeddings are generated for semantic search. 4. Content is stored for retrieval and optionally linked to the knowledge graph. In a **full** R2R installation, ingestion is asynchronous. You can monitor ingestion status and confirm when documents are ready: ```zsh client.documents.list() # [ # DocumentResponse( # id=UUID('e43864f5-a36f-548e-aacd-6f8d48b30c7f'), # collection_ids=[UUID('122fdf6a-e116-546b-a8f6-e4cb2e2c0a09')], # owner_id=UUID('2acb499e-8428-543b-bd85-0d9098718220'), # document_type=, # metadata={'title': 'DeepSeek_R1.pdf', 'version': 'v0'}, # version='v0', # size_in_bytes=1768572, # ingestion_status=, # extraction_status=, # created_at=datetime.datetime(2025, 2, 8, 3, 31, 39, 126759, tzinfo=TzInfo(UTC)), # updated_at=datetime.datetime(2025, 2, 8, 3, 31, 39, 160114, tzinfo=TzInfo(UTC)), # ingestion_attempt_number=None, # summary="The document contains a comprehensive overview of DeepSeek-R1, a series of reasoning models developed by DeepSeek-AI, which includes DeepSeek-R1-Zero and DeepSeek-R1. DeepSeek-R1-Zero utilizes large-scale reinforcement learning (RL) without supervised fine-tuning, showcasing impressive reasoning capabilities but facing challenges like readability and language mixing. To enhance performance, DeepSeek-R1 incorporates multi-stage training and cold-start data, achieving results comparable to OpenAI's models on various reasoning tasks. The document details the models' training processes, evaluation results across multiple benchmarks, and the introduction of distilled models that maintain reasoning capabilities while being smaller and more efficient. It also discusses the limitations of current models, such as language mixing and sensitivity to prompts, and outlines future research directions to improve general capabilities and efficiency in software engineering tasks. The findings emphasize the potential of RL in developing reasoning abilities in large language models and the effectiveness of distillation techniques for smaller models.", summary_embedding=None, total_tokens=29673)] total_entries=1 # ), ... # ] ``` An `ingestion_status` of `"success"` confirms the document is fully ingested. You can also check the R2R dashboard at http://localhost:7273 for ingestion progress and status. For more details on creating documents, [refer to the Create Document API](/api-and-sdks/documents/create-document). ## Ingesting Pre-Processed Chunks If you have pre-processed chunks from your own pipeline, you can directly ingest them. This is especially useful if you've already divided content into logical segments. ```python chunks = ["This is my first parsed chunk", "This is my second parsed chunk"] client.documents.create( chunks=chunks, ingestion_mode="fast" # use fast for a quick chunk ingestion ) ``` ## Deleting Documents and Chunks To remove documents or chunks, call their respective `delete` methods: ```python # Delete a document delete_response = client.documents.delete(document_id) # Delete a chunk delete_response = client.chunks.delete(chunk_id) ``` You can also delete documents by specifying filters using the [`by-filter`](/api-and-sdks/documents/delete-document-by-filter) route. ## Additional Configuration & Concepts - **Light vs. Full Deployments:** - Light (default) uses R2R's built-in parser and supports synchronous ingestion. - Full deployments orchestrate ingestion tasks asynchronously and integrate with more complex providers like `unstructured_local`. - **Provider Configuration:** Settings in `r2r.toml` or at runtime (`ingestion_config`) can adjust parsing and chunking strategies: - `fast` and `hi-res` modes are influenced by strategies like `"auto"` or `"hi_res"` in the unstructured provider. - `custom` mode allows you to override chunk size, overlap, excluded parsers, and more at runtime. For detailed configuration options, see: - [Data Ingestion Configuration](/self-hosting/configuration/ingestion) ## Conclusion R2R's ingestion is flexible and efficient, allowing you to tailor ingestion to your needs: - Use `fast` for quick processing. - Use `hi-res` for high-quality, multimodal analysis. - Use `custom` for advanced, granular control. You can easily ingest documents or pre-processed chunks, update their content, and delete them when no longer needed. Combined with powerful retrieval and knowledge graph capabilities, R2R enables seamless integration of advanced document management into your applications. ================================================ FILE: docs/cookbooks/local.md ================================================ There are many amazing LLMs and embedding models that can be run locally. R2R fully supports using these models, giving you full control over your data and infrastructure. Running models locally can be ideal for sensitive data handling, reducing API costs, or situations where internet connectivity is limited. While cloud-based LLMs often provide cutting-edge performance, local models offer a compelling balance of capability, privacy, and cost-effectiveness for many use cases. ### Serving Local Models For this cookbook, we'll serve our local models via Ollama. [You may follow the instructions on their official website to install.](https://ollama.com/) You can also follow along using LM Studio. To get started with LM Studio, see our [Local LLM documentation](/self-hosting/local-rag). R2R supports [LiteLLM](https://github.com/BerriAI/litellm) for routing embedding and completion requests. This allows for OpenAI-compatible endpoints to be called and seamlessly routed to, if you are serving local models another way. We must first download the models that we wish to run and start our ollama server. The following command will 'pull' the models and begin the Ollama server via `http://localhost:11434`. ```zsh ollama pull llama3.1 ollama pull mxbai-embed-large ``` Ollama has a default context window size of 2048 tokens. Many of the prompts and processes that R2R uses requires larger window sizes. It is recommended to set the context size to a minimum of 16k tokens. The following guideline is generally useful to determine what your system can handle: - 8GB RAM/VRAM: ~4K-8K context - 16GB RAM/VRAM: ~16K-32K context - 24GB+ RAM/VRAM: 32K+ context To change the default context window you must first create a Modelfile for Ollama, where you can set `num_ctx`: ```Zsh echo 'FROM llama3.1 PARAMETER num_ctx 16000' > Modelfile ``` Then you must create a manifest for that model: ```Zsh ollama create llama3.1 -f Modelfile ``` Then, we can start the Ollama server: ```Zsh ollama serve ``` ### Configuring R2R Now that our models have been loaded and our Ollama server is ready, we can launch our R2R server. The standard distribution of R2R includes a configuration file for running `llama3.1` and `mxbai-embed-large`. If you wish to utilize other models, you must create a custom config file and pass this to your server. ```Toml [app] # LLM used for internal operations, like deriving conversation names fast_llm = "ollama/llama3.1" # LLM used for user-facing output, like RAG replies quality_llm = "ollama/llama3.1" # LLM used for ingesting visual inputs vlm = "ollama/llama3.2-vision" # TODO - Replace with viable candidate # LLM used for transcription audio_lm = "ollama/llama3.1" # TODO - Replace with viable candidate [embedding] provider = "ollama" base_model = "mxbai-embed-large" base_dimension = 1_024 batch_size = 128 add_title_as_prefix = true concurrent_request_limit = 2 [completion_embedding] provider = "ollama" base_model = "mxbai-embed-large" base_dimension = 1_024 batch_size = 128 add_title_as_prefix = true concurrent_request_limit = 2 [agent] tools = ["local_search"] [agent.generation_config] model = "ollama/llama3.1" [completion] provider = "litellm" concurrent_request_limit = 1 [completion.generation_config] temperature = 0.1 top_p = 1 max_tokens_to_sample = 1_024 stream = false ``` We launch R2R by specifying this configuration file: ```Zsh export R2R_CONFIG_NAME=ollama python -m r2r.serve ``` Since we're serving with Docker, once R2R successfully launches the R2R dashboard opens for us. We can upload a document and see requests hit our Ollama server. The processed document and the Ollama server logs. ### Retrieval and Search Now that we have ingested our file, we can perform RAG and chunk search over it. Here, we see that we are able to get relevant results and correct answers—all without needing to make a request out to an external provider! A RAG search done with local LLMs. A semantic serach done with LLMs. ### Extracting Entities and Relationships If we'd like to build a graph for our document, we must first extract the entities and relationships that it contains. Through the dashboard we can select the 'Document Extraction' action in the documents table. This will start the extraction process in the background, which uses named entity recognition to find entities and relationships. Note that this process can take quite a bit of time, depending on the size of your document and the hardware running your model. Once the process is complete, we will see that the `extraction` status has turned green. Successful extraction on the documents table. A semantic serach done with LLMs. A semantic serach done with LLMs. ### Graph RAG Now we must `pull` the document extractions into the graph. This is done at the collection level, and creates a copy of our extractions for searching over and creating communities with. Then, we can conduct search, RAG, or agent queries that utilize the graph. A search that utilizes the entities and relationships from the graph. A semantic serach done with LLMs. ### Building communities We can go one step further and create communities over the entities and relationships in the graph. By clustering over the closely related extractions, we can further develop the understanding of how these entities and relationships interact. This can be particularly helpful in sets of documents where we see overarching or recuring themes. We trigger the extraction procedure, which produces a number of communities. Now, when we run queries over our graph we can utilize the communities to provide context that better encompasses overall concepts and ideas throughout our documents. A RAG search that utilizes communities. A semantic serach done with LLMs. ================================================ FILE: docs/cookbooks/logging.md ================================================ Users deploying R2R into production settings benefit from robust, persistant logging. R2R supports this via [Victorialogs](https://docs.victoriametrics.com/victorialogs), open source user-friendly database for logs from [VictoriaMetrics](https://docs.victoriametrics.com). Victorialogs ships by default with the [full version of R2R](/self-hosting/installation/full) and hosts a UI to view your logs at http://localhost:9428/select/vmui. ## Accessing Logs ### VictoriaLogs UI The easiest way to view logs is through the VictoriaLogs UI: Navigate to http://localhost:9428/select/vmui. The VictoriaLogs UI. Use the query box to search for specific log entries. Querying logs. Adjust the time range as needed using the time controls Filtering logs by time. ### Common Query Examples Here are some useful queries for finding specific log information: ```json # View all logs * # View logs with [ERROR] tag {log=~"\\[ERROR\\].*"} # View logs with error-related content {log=~".*error.*"} {log=~".*exception.*"} {log=~".*traceback.*"} {log=~".*failed.*"} # View logs with warning content {log=~".*WARNING.*"} # View logs about a specific process {log=~".*ingestion.*"} # View specific error types {log=~".*HTTPException.*"} {log=~".*ValueError.*"} # View Azure OpenAI-related errors {log=~".*OpenAI.*"} ``` ## Troubleshooting Common Issues ### No Logs Showing Up If you don't see any logs: 1. Increase the time range - logs might be outside your current time window 2. Check if Fluent Bit is running: `docker ps | grep fluent-bit` 3. Check VictoriaLogs is running: `docker ps | grep victoria-logs` 4. Verify your R2R container is properly configured for logging ### Understanding Error Logs When you see an error in the logs, it typically follows this pattern: 1. Error message with timestamp 2. A traceback showing the sequence of function calls 3. The specific error and its cause Look for the actual error message at the bottom of a traceback to understand the root cause. ## Advanced Configuration ### Customizing Fluent Bit If you need to customize how logs are collected and processed, you can modify the Fluent Bit configuration: 1. Create/edit the `fluent-bit.conf` file in your `./fluent-bit` directory 2. Restart the Fluent Bit container: `docker restart docker-fluent-bit-1` ### Setting Up Grafana for Log Visualization For more advanced visualization, you can connect Grafana to VictoriaLogs: 1. Access Grafana at http://localhost:3001 2. Add a new VictoriaLogs data source: - Go to Configuration > Data Sources > Add data source - Select "VictoriaMetrics Logs" - Set URL to http://victoria-logs:9428 - Save and test the connection 3. Create a new dashboard with a Logs panel 4. Configure the panel to query logs using the same query syntax as in the VictoriaLogs UI ## Retention Policy By default, logs are retained for 60 days as configured in the Docker Compose file: ```yaml victoria-logs: image: victoriametrics/victoria-logs:v1.10.1-victorialogs command: -storageDataPath=/data -retentionPeriod=60d ``` To change the retention period, modify the `-retentionPeriod` parameter and restart the container. ## Log Format Each log entry contains: - `_time`: Timestamp of the log - `container_name`: Source container - `log`: The actual log message - Additional metadata When searching logs, you'll typically want to search for content in the `log` field. ================================================ FILE: docs/cookbooks/maintenance.md ================================================ This guide covers essential maintenance tasks for R2R deployments, with a focus on vector index management and system updates. Understanding when and how to build vector indices, as well as keeping your R2R installation current, is crucial for maintaining optimal performance at scale. ## PostgreSQL VACUUM PostgreSQL's VACUUM operation is a critical maintenance process that reclaims storage space occupied by deleted or obsolete data, updates statistics for the query planner to optimize performance prevents transaction ID wraparound issues, and improves overall database performance. In normal PostgreSQL operation, when you delete or update rows, the original data is not immediately removed from disk but marked as obsolete. These obsolete rows (called "dead tuples") accumulate over time, consuming disk space and potentially slowing down queries. R2R includes automatic scheduled maintenance to optimize your PostgreSQL database: ```toml [database.maintenance] vacuum_schedule = "0 3 * * *" # Run at 3:00 AM daily ``` Regular vacuum operations keep your database healthy, however it's recommended to schedule these operations during periods of low system usage. ## Vector Indices ### Do You Need Vector Indices? Vector indices are **not necessary for all deployments**, especially in multi-user applications where each user typically queries their own subset of documents. Consider that: - In multi-user applications, queries are usually filtered by user_id, drastically reducing the actual number of vectors being searched - A system with 1 million total vectors but 1000 users might only search through 1000 vectors per query - Performance impact of not having indices is minimal when searching small per-user document sets Only consider implementing vector indices when: - Individual users are searching across hundreds of thousands of documents - Query latency becomes a bottleneck even with user-specific filtering - You need to support cross-user search functionality at scale For development environments or smaller deployments, the overhead of maintaining vector indices often outweighs their benefits. ### Vector Index Management R2R supports multiple indexing methods, with HNSW (Hierarchical Navigable Small World) being recommended for most use cases: ```python # Create vector index create_response = client.indices.create( { "table_name": "vectors", "index_method": "hnsw", "index_measure": "cosine_distance", "index_arguments": { "m": 16, # Number of connections per element "ef_construction": 64 # Size of dynamic candidate list }, } ) # List existing indices indices = client.indices.list() # Delete an index delete_response = client.indices.delete( index_name="ix_vector_cosine_ops_hnsw__20241021211541", table_name="vectors", ) print('delete_response = ', delete_response) ``` #### Important Considerations 1. **Pre-warming Requirement** - New indices start "cold" and require warming for optimal performance - Initial queries will be slower until the index is loaded into memory - Consider implementing explicit pre-warming in production - Warming must be repeated after system restarts 2. **Resource Usage** - Index creation is CPU and memory intensive - Memory usage scales with both dataset size and `m` parameter - Consider creating indices during off-peak hours 3. **Performance Tuning** - HNSW Parameters: - `m`: 16-64 (higher = better quality, more memory) - `ef_construction`: 64-100 (higher = better quality, longer build time) - Distance Measures: - `cosine_distance`: Best for normalized vectors (most common) - `l2_distance`: Better for absolute distances - `max_inner_product`: Optimized for dot product similarity ## Scaling Strategies ### Horizontal Scaling For applications serving many users, it is advantageous to scale the number of R2R replicas horizontally. This improves concurrent handling of requests and reliability. 1. **Load Balancing** - Deploy multiple R2R replicas behind a load balancer - Requests are distributed amongst the replicas - Particularly effective since most queries are user-specific 2. **Sharding** - Consider sharding by user_id for large multi-user deployments - Each shard handles a subset of users - Maintains performance even with millions of total documents #### Horizontal Scaling with Docker Swarm R2R ships with an example compose file to deploy to [Swarm](https://docs.docker.com/engine/swarm/), an advanced Docker feature that manages a cluster of Docker daemons. After cloning the R2R repository, we can initialize Swarm and start our stack: ```zsh # Set the number of R2R replicas to create, defaults to 3 if not set export R2R_REPLICAS=3 # Initialize swarm (if not already running) docker swarm init # Create overlay networks docker network create --driver overlay r2r_r2r-network # Source environment file set -a source /path/to/.env set +a # Deploy stacks docker stack deploy -c R2R/py/r2r/compose.swarm.yaml r2r # Commands to bring down stacks (when needed) docker stack rm r2r ``` ### Vertical Scaling For applications requiring large single-user searches: 1. **Cloud Provider Solutions** - AWS RDS supports up to 1 billion vectors per instance - Scale up compute and memory resources as needed - Example instance types: - `db.r6g.16xlarge`: Suitable for up to 100M vectors - `db.r6g.metal`: Can handle 1B+ vectors 2. **Memory Optimization** ```python # Optimize for large vector collections client.indices.create( table_name="vectors", index_method="hnsw", index_arguments={ "m": 32, # Increased for better performance "ef_construction": 80 # Balanced for large collections } ) ``` ### Multi-User Considerations 1. **Filtering Optimization** ```python # Efficient per-user search response = client.retrieval.search( "query", search_settings={ "filters": { "user_id": {"$eq": "current_user_id"} } } ) ``` 2. **Collection Management** - Group related documents into collections - Enable efficient access control - Optimize search scope 3. **Resource Allocation** - Monitor per-user resource usage - Implement usage quotas if needed - Consider dedicated instances for power users ### Performance Monitoring Monitor these metrics to inform scaling decisions: 1. **Query Performance** - Average query latency per user - Number of vectors searched per query - Cache hit rates 2. **System Resources** - Memory usage per instance - CPU utilization - Storage growth rate 3. **User Patterns** - Number of active users - Query patterns and peak usage times - Document count per user ================================================ FILE: docs/cookbooks/mcp.md ================================================ The R2R Retrieval System is a Model Context Protocol (MCP) server that enhances Claude with retrieval and search capabilities. This server enables Claude to search through your knowledge base, perform vector searches, graph searches, web searches, and document searches, making it a powerful tool for retrieving relevant information. ## Features - **Vector Search**: Find relevant text chunks based on semantic similarity - **Graph Search**: Explore relationships between entities in your knowledge graph - **Web Search**: Retrieve information from online sources - **Document Search**: Access and query local context documents - **RAG (Retrieval-Augmented Generation)**: Generate answers based on retrieved context ## Installation ### Prerequisites - Claude Desktop (macOS or Windows) - Node.js - Python 3.6 or higher - `mcp` Python package ### Local Installation 1. Install the R2R MCP server locally: ```bash pip install mcp mcp install r2r/mcp.py -v R2R_API_URL=http://localhost:7272 ``` 2. Start your local R2R API service at the specified URL. ### Cloud Installation For cloud deployment, use your API key: ```bash pip install mcp mcp install r2r/mcp.py -v R2R_API_KEY=your_api_key_here ``` ## Adding to Claude Desktop **Note: This section is only necessary if the pip installation method fails.** In most cases, the pip installation above should be sufficient to make the R2R server available to Claude. 1. Open Claude Desktop and access the Settings: - On macOS: Click on the Claude menu and select "Settings..." - On Windows: Click on the Claude menu and select "Settings..." 2. In Settings, click on "Developer" in the left sidebar, then click "Edit Config" 3. Add the R2R server to your configuration file: ```json { "mcpServers": { "r2r": { "command": "mcp", "args": ["run", "/my/path/to/R2R/py/r2r/mcp.py"] } } } ``` 4. Save the configuration file and restart Claude Desktop 5. After restarting, you should see the hammer icon in the bottom right corner of the input box, indicating that MCP tools are available ## Using the R2R Retrieval System Once configured, Claude can automatically use the R2R tools when appropriate. You can also explicitly request Claude to use these tools: - **Search**: Ask Claude to search your knowledge base with specific queries Example: "Search for information about vector databases in our documentation" - **RAG**: Request Claude to generate answers based on retrieved context Example: "Use RAG to answer: What are the best practices for knowledge graph integration?" ## Available Tools The R2R server provides two primary tools: 1. **search**: Performs retrieval operations and returns formatted results - Searches across vector, graph, web, and document sources - Returns source IDs and content for further reference 2. **rag**: Performs Retrieval-Augmented Generation - Retrieves relevant context and generates an answer - Provides a coherent response based on the knowledge base ## Example Outputs When using the search tool, you'll receive structured results like: ``` Vector Search Results: Source ID [abc1234]: Text content from the vector search... Graph Search Results: Source ID [def5678]: Entity Name: Sample Entity Description: This is a description of the entity...

For specific questions about the R2R Retrieval System, please contact your system administrator or developer. ================================================ FILE: docs/cookbooks/orchestration.md ================================================ R2R uses [Hatchet](https://docs.hatchet.run/home) for orchestrating complex workflows, particularly for ingestion and knowledge graph construction processes. Hatchet is a distributed, fault-tolerant task queue that solves scaling problems like concurrency, fairness, and rate limiting. It allows R2R to distribute functions between workers with minimal configuration. ### Key Concepts 1. **Workflows**: Sets of functions executed in response to external triggers. 2. **Workers**: Long-running processes that execute workflow functions. 3. **Managed Queue**: Low-latency queue for handling real-time tasks. ## Orchestration in R2R ### Benefits of orchestration 1. **Scalability**: Efficiently handles large-scale tasks. 2. **Fault Tolerance**: Built-in retry mechanisms and error handling. 3. **Flexibility**: Easy to add or modify workflows as R2R's capabilities expand. ### Workflows in R2R 1. **IngestFilesWorkflow**: Handles file ingestion, parsing, chunking, and embedding. 2. **UpdateFilesWorkflow**: Manages the process of updating existing files. 3. **KgExtractAndStoreWorkflow**: Extracts and stores knowledge graph information. 4. **CreateGraphWorkflow**: Orchestrates the creation of knowledge graphs. 5. **EnrichGraphWorkflow**: Handles graph enrichment processes like node creation and clustering. ## Orchestration GUI By default, the R2R Docker ships with with Hatchet's front-end application on port 7274. This can be accessed by navigating to `http://localhost:7274`. You may login with the following credentials: **Email:** admin@example.com **Password:** Admin123!! ### Login ### Running Tasks The panel below shows the state of the Hatchet workflow panel at `http://localhost:7274/workflow-runs` immediately after calling `r2r documents create-samples`: ### Inspecting a workflow You can inspect a workflow within Hatchet and can even attempt to retry the job from directly in the GUI in the case of failure: ### Long running tasks Hatchet supports long running tasks, which is very useful during knowledge graph construction: ## Coming Soon In the coming day(s) / week(s) we will further highlight the available feature set and best practices for orchestrating your ingestion workflows inside R2R. ================================================ FILE: docs/cookbooks/structured-output.md ================================================ Structured outputs allow users to ensure that the retrieval response generated by the LLM follows a user-defined structure. This provides reliable type-safety, making it easier to generate high-quality, production-ready applications. R2R supports passing Pydantic models via our Python SDK. With this, you can: - Define the exact structure you expect for responses - Automatically validate that responses match your schema - Access response fields with proper typing and autocompletion - Handle errors gracefully when responses don't match expectations ## Using Structured Outputs with R2R The example below demonstrates how to define a simple Pydantic model that specifies the expected structure for responses to a query about Hopfield Networks. The model includes fields for the main answer, a confidence score, additional comments, and even a related joke. ```Python from r2r import R2RClient, GenerationConfig from pydantic import BaseModel import json # Define a response model class ResponseModel(BaseModel): answer: str confidence: float comments: str related_joke: str rag_response = client.retrieval.rag( query="What is a Hopfield Network?", rag_generation_config=GenerationConfig( response_format=ResponseModel ) ) ``` ## Processing the Response Once you've received a response, you can parse it as JSON and validate it against your Pydantic model. This ensures that the response contains all required fields with the correct data types. ```Python content = json.loads(rag_response.results.completion) print(json.dumps(content, indent=2)) response_obj = ResponseModel.model_validate(content) print("\nAs a Pydantic object:") print(f"Confidence: {response_obj.confidence}") print(f"Comments: {response_obj.comments}") print(f"Related Joke: {response_obj.related_joke}") print("\nDetailed Answer:") print(response_obj.answer) ``` ## Example Output Here's what the output looks like when running the code above: ```zsh wordWrap { "answer": "A Hopfield Network is a type of recurrent neural network introduced by John Hopfield in 1982, designed to function as an associative memory system. It consists of binary nodes with symmetric weights, and its dynamics are governed by an energy function that decreases over time, leading the network to stable states that represent stored memories [1], [2].", "confidence": 0.95, "comments": "The Hopfield Network is a foundational concept in neural networks, and its principles are widely studied in computational neuroscience and machine learning.", "related_joke": "Why did the neural network go to therapy? It had too many weights to carry!" } As a Pydantic object: Confidence: 0.95 Comments: The Hopfield Network is a foundational concept in neural networks, and its principles are widely studied in computational neuroscience and machine learning. Related Joke: Why did the neural network go to therapy? It had too many weights to carry! Detailed Answer: A Hopfield Network is a type of recurrent neural network introduced by John Hopfield in 1982, designed to function as an associative memory system. It consists of binary nodes with symmetric weights, and its dynamics are governed by an energy function that decreases over time, leading the network to stable states that represent stored memories [1], [2]. ``` ================================================ FILE: docs/cookbooks/web-dev.md ================================================ Web developers can easily integrate R2R into their projects using the [R2R JavaScript client](https://www.npmjs.com/package/r2r-js). For more extensive reference and examples of how to use the r2r-js library, we encourage you to look at the [R2R Application](https://github.com/SciPhi-AI/R2R-Application) and its source code. ## Hello R2R—JavaScript R2R gives developers configurable vector search and RAG right out of the box, as well as direct method calls instead of the client-server architecture seen throughout the docs: ```python const { r2rClient } = require("r2r-js"); const client = new r2rClient("http://localhost:7272"); async function main() { const files = [ { path: "examples/data/raskolnikov.txt", name: "raskolnikov.txt" }, ]; const EMAIL = "admin@example.com"; const PASSWORD = "change_me_immediately"; console.log("Logging in..."); await client.users.login(EMAIL, PASSWORD); console.log("Ingesting file..."); const documentResult = await client.documents.create({ file: { path: "examples/data/raskolnikov.txt", name: "raskolnikov.txt" }, metadata: { title: "raskolnikov.txt" }, }); console.log("Document result:", JSON.stringify(documentResult, null, 2)); console.log("Performing RAG..."); const ragResponse = await client.rag({ query: "What does the file talk about?", rag_generation_config: { model: "openai/gpt-4o", temperature: 0.0, stream: false, }, }); console.log("Search Results:"); ragResponse.results.search_results.chunk_search_results.forEach( (result, index) => { console.log(`\nResult ${index + 1}:`); console.log(`Text: ${result.metadata.text.substring(0, 100)}...`); console.log(`Score: ${result.score}`); }, ); console.log("\nCompletion:"); console.log(ragResponse.results.completion.choices[0].message.content); } main(); ``` ## r2r-js Client ### Installing To get started, install the R2R JavaScript client with [npm](https://www.npmjs.com/package/r2r-js): ```zsh npm install r2r-js ``` ### Creating the Client First, we create the R2R client and specify the base URL where the R2R server is running: ```javascript const { r2rClient } = require("r2r-js"); // http://localhost:7272 or the address that you are running the R2R server const client = new r2rClient("http://localhost:7272"); ``` ### Log into the server Sign into the server to authenticate the session. We'll use the default superuser credentials: ```javascript const EMAIL = "admin@example.com"; const PASSWORD = "change_me_immediately"; console.log("Logging in..."); await client.users.login(EMAIL, PASSWORD); ``` ### Ingesting Files Specify the files that we'll ingest: ```javascript const file = { path: "examples/data/raskolnikov.txt", name: "raskolnikov.txt" } ]; console.log("Ingesting file..."); const ingestResult = await client.documents.create( file: { path: "examples/data/raskolnikov.txt", name: "raskolnikov.txt" }, metadata: { title: "raskolnikov.txt" }, ) console.log("Ingest result:", JSON.stringify(ingestResult, null, 2)); ... /* Ingest result: { "results": { "processed_documents": [ "Document 'raskolnikov.txt' processed successfully." ], "failed_documents": [], "skipped_documents": [] } } */ ``` This command processes the ingested, splits them into chunks, embeds the chunks, and stores them into your specified Postgres database. Relational data is also stored to allow for downstream document management, which you can read about in the [quickstart](/documentation/quickstart). ### Performing RAG We'll make a RAG request, ```javascript console.log("Performing RAG..."); const ragResponse = await client.rag({ query: "What does the file talk about?", rag_generation_config: { model: "openai/gpt-4o", temperature: 0.0, stream: false, }, }); console.log("Search Results:"); ragResponse.results.search_results.chunk_search_results.forEach( (result, index) => { console.log(`\nResult ${index + 1}:`); console.log(`Text: ${result.metadata.text.substring(0, 100)}...`); console.log(`Score: ${result.score}`); }, ); console.log("\nCompletion:"); console.log(ragResponse.results.completion.choices[0].message.content); ... /* Performing RAG...

His room, which is more like a closet than a proper room, is located under the roof of the five-story house, while the landlady lives on the floor below and provides him with meals and services [2]. */ ``` ## Connecting to a Web App R2R can be easily integrated into web applications. We'll create a simple Next.js app that uses R2R for query answering. [We've created a template repository with this code.](https://github.com/SciPhi-AI/r2r-webdev-template) Alternatively, you can add the code below to your own Next.js project. ![R2R Dashboard Overview](/images/R2R_Web_Dev_Template.png) ### Setting up an API Route First, we'll create an API route to handle R2R queries. Create a file named `r2r-query.ts` in the `pages/api` directory: ```typescript import { NextApiRequest, NextApiResponse } from 'next'; import { r2rClient } from 'r2r-js'; const client = new r2rClient("http://localhost:7272"); export default async function handler(req: NextApiRequest, res: NextApiResponse) { if (req.method === 'POST') { const { query } = req.body; try { // Login with each request. In a production app, you'd want to manage sessions. await client.users.login("admin@example.com", "change_me_immediately"); const response = await client.rag({ query: query, rag_generation_config: { model: "openai/gpt-4o", temperature: 0.0, stream: false, } }); res.status(200).json({ result: response.results.completion.choices[0].message.content }); } catch (error) { res.status(500).json({ error: error instanceof Error ? error.message : 'An error occurred' }); } } else { res.setHeader('Allow', ['POST']); res.status(405).end(`Method ${req.method} Not Allowed`); } } ``` This API route creates an R2R client, logs in, and processes the incoming query using the RAG method. ### Frontend: React Component Next, create a React component to interact with the API. Here's an example `index.tsx` file: ```tsx import React, { useState } from 'react'; import styles from '@/styles/R2RWebDevTemplate.module.css'; const R2RQueryApp: React.FC = () => { const [query, setQuery] = useState(''); const [result, setResult] = useState(''); const [isLoading, setIsLoading] = useState(false); const performQuery = async () => { setIsLoading(true); setResult(''); try { const response = await fetch('/api/r2r-query', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ query }), }); if (!response.ok) { throw new Error('Network response was not ok'); } const data = await response.json(); setResult(data.result); } catch (error) { setResult(`Error: ${error instanceof Error ? error.message : String(error)}`); } finally { setIsLoading(false); } }; return (

R2R Web Dev Template

A simple template for making RAG queries with R2R. Make sure that your R2R server is up and running, and that you've ingested files!

Check out the R2R Documentation for more information.

setQuery(e.target.value)} placeholder="Enter your query here" className={styles.queryInput} /> {isLoading ? (
) : (
{result}
)}
); }; export default R2RQueryApp; ``` This component creates a simple interface with an input field for the query and a button to submit it. When the button is clicked, it sends a request to the API route we created earlier and displays the result. ### Template Repository For a complete working example, you can check out our template repository. This repository contains a simple Next.js app with R2R integration, providing a starting point for your own R2R-powered web applications.

[Next Steps](#next-steps) ## Create an Account > **Note**: For those interested in deploying R2R locally, please refer to our [local installation guide](../self-hosting/getting-started/installation/overview.md). ## Install the SDK R2R offers Python and JavaScript SDKs to interact with the system. ### Python ```bash pip install r2r ``` ### JavaScript ```bash npm i r2r-js ``` ## Initialize the Client ### Python ```python # export R2R_API_KEY=... from r2r import R2RClient client = R2RClient() # can set remote w/ R2RClient(base_url=...) # or, alternatively, client.users.login("my@email.com", "my_strong_password") ``` ### JavaScript ```javascript // export R2R_API_KEY=... const { r2rClient } = require('r2r-js'); const client = new r2rClient(); // can set baseURL=... // or, alternatively, client.users.login("my@email.com", "my_strong_password") ``` ## Ingesting Files When you ingest files into R2R, the server accepts the task, processes and chunks the file, and generates a summary of the document. ### Python ```python client.documents.create_sample(hi_res=True) # to ingest your own document, client.documents.create(file_path="/path/to/file") ``` ### JavaScript ```javascript client.documents.createSample({ ingestionMode: "hi-res" }) // to ingest your own document, client.documents.create({filePath: }) ``` Example output: ```plaintext IngestionResponse(message='Document created and ingested successfully.', task_id=None, document_id=UUID('e43864f5-a36f-548e-aacd-6f8d48b30c7f')) ``` ## Getting File Status After file ingestion is complete, you can check the status of your documents by listing them. ### Python ```python client.documents.list() ``` ### JavaScript ```javascript client.documents.list() ``` ### cURL ```bash curl -X GET http://localhost:7272/v3/documents \ -H "Content-Type: application/json" ``` Example output: ```plaintext [ DocumentResponse( id=UUID('e43864f5-a36f-548e-aacd-6f8d48b30c7f'), collection_ids=[UUID('122fdf6a-e116-546b-a8f6-e4cb2e2c0a09')], owner_id=UUID('2acb499e-8428-543b-bd85-0d9098718220'), document_type=, metadata={'title': 'DeepSeek_R1.pdf', 'version': 'v0'}, version='v0', size_in_bytes=1768572, ingestion_status=, extraction_status=, created_at=datetime.datetime(2025, 2, 8, 3, 31, 39, 126759, tzinfo=TzInfo(UTC)), updated_at=datetime.datetime(2025, 2, 8, 3, 31, 39, 160114, tzinfo=TzInfo(UTC)), ingestion_attempt_number=None, summary="The document contains a comprehensive overview of DeepSeek-R1...", summary_embedding=None, total_tokens=29673 ), ... ] ``` ## Executing a Search Perform a search query: ### Python ```python client.retrieval.search( query="What is DeepSeek R1?", ) ``` ### JavaScript ```javascript client.retrieval.search({ query: "What is DeepSeek R1?", }) ``` ### cURL ```bash curl -X POST http://localhost:7272/v3/retrieval/search \ -H "Content-Type: application/json" \ -d '{ "query": "What is DeepSeek R1?" }' ``` The search query will use basic similarity search to find the most relevant documents. You can use advanced search methods like [hybrid search](../documentation/retrieval/hybrid-search.md) or [graph search](../documentation/general/graphs.md) depending on your use case. Example output: ```plaintext AggregateSearchResult( chunk_search_results=[ ChunkSearchResult( score=0.643, text="Document Title: DeepSeek_R1.pdf Text: could achieve an accuracy of over 70%. DeepSeek-R1 also delivers impressive results on IF-Eval..." ), ... ], graph_search_results=[], web_search_results=[], context_document_results=[] ) ``` ## RAG (Retrieval-Augmented Generation) Generate a RAG response: ### Python ```python client.retrieval.rag( query="What is DeepSeek R1?", ) ``` ### JavaScript ```javascript client.retrieval.rag({ query: "What is DeepSeek R1?", }) ``` ### cURL ```bash curl -X POST http://localhost:7272/v3/retrieval/rag \ -H "Content-Type: application/json" \ -d '{ "query": "What is DeepSeek R1?" }' ``` Example output: ```plaintext RAGResponse( generated_answer='DeepSeek-R1 is a model that demonstrates impressive performance across various tasks, leveraging reinforcement learning (RL) and supervised fine-tuning (SFT) to enhance its capabilities...', search_results=AggregateSearchResult(...), citations=[Citation(id='cit_3a35e39', object='citation', ...)], metadata={...} ) ``` ## Streaming RAG Generate a streaming RAG response: ### Python ```python from r2r import ( CitationEvent, FinalAnswerEvent, MessageEvent, SearchResultsEvent, R2RClient, ) result_stream = client.retrieval.rag( query="What is DeepSeek R1?", search_settings={"limit": 25}, rag_generation_config={"stream": True}, ) # can also do a switch on `type` field for event in result_stream: if isinstance(event, SearchResultsEvent): print("Search results:", event.data) elif isinstance(event, MessageEvent): print("Partial message:", event.data.delta) elif isinstance(event, CitationEvent): print("New citation detected:", event.data) elif isinstance(event, FinalAnswerEvent): print("Final answer:", event.data.generated_answer) ``` ### JavaScript ```javascript // 1) Initiate a streaming RAG request const resultStream = await client.retrieval.rag({ query: "What is DeepSeek R1?", searchSettings: { limit: 25 }, ragGenerationConfig: { stream: true }, }); // 2) Check if we got an async iterator (streaming) if (Symbol.asyncIterator in resultStream) { // 2a) Loop over each event from the server for await (const event of resultStream) { switch (event.event) { case "search_results": console.log("Search results:", event.data); break; case "message": console.log("Partial message delta:", event.data.delta); break; case "citation": console.log("New citation event:", event.data); break; case "final_answer": console.log("Final answer:", event.data.generated_answer); break; default: console.log("Unknown or unhandled event:", event); } } } else { // 2b) If streaming was NOT enabled or server didn't send SSE, // we'd get a single response object instead. console.log("Non-streaming RAG response:", resultStream); } ``` Example output: ```plaintext Search results: id='run_1' object='rag.search_results' data={'chunk_search_results': [...]} Partial message: {'content': [MessageDelta(type='text', text={'value': 'Deep', 'annotations': []})]} Partial message: {'content': [MessageDelta(type='text', text={'value': 'Seek', 'annotations': []})]} New Citation Detected: 'cit_3a35e39' Final answer: DeepSeek-R1 is a large language model developed by the DeepSeek-AI research team... ``` ## Streaming Agentic RAG R2R offers a powerful `agentic` retrieval mode that performs in-depth analysis of documents through iterative research and reasoning. This mode can leverage a variety of tools to thoroughly investigate your data and the web: ### Python ```python from r2r import ( ThinkingEvent, ToolCallEvent, ToolResultEvent, CitationEvent, FinalAnswerEvent, MessageEvent, R2RClient, ) results = client.retrieval.agent( message={"role": "user", "content": "What does deepseek r1 imply for the future of AI?"}, rag_generation_config={ "model": "anthropic/claude-3-7-sonnet-20250219", "extended_thinking": True, "thinking_budget": 4096, "temperature": 1, "top_p": None, "max_tokens_to_sample": 16000, "stream": True }, ) # Process the streaming events for event in results: if isinstance(event, ThinkingEvent): print(f"🧠 Thinking: {event.data.delta.content[0].payload.value}") elif isinstance(event, ToolCallEvent): print(f"🔧 Tool call: {event.data.name}({event.data.arguments})") elif isinstance(event, ToolResultEvent): print(f"📊 Tool result: {event.data.content[:60]}...") elif isinstance(event, CitationEvent): print(f"📑 Citation: {event.data}") elif isinstance(event, MessageEvent): print(f"💬 Message: {event.data.delta.content[0].payload.value}") elif isinstance(event, FinalAnswerEvent): print(f"✅ Final answer: {event.data.generated_answer[:100]}...") print(f" Citations: {len(event.data.citations)} sources referenced") ``` ### JavaScript ```javascript const resultStream = await client.retrieval.agent({ message: {role: "user", content: "What does deepseek r1 imply for the future of AI?"}, generationConfig: { stream: true } }); // Process the streaming events if (Symbol.asyncIterator in resultStream) { for await (const event of resultStream) { switch(event.event) { case "thinking": console.log(`🧠 Thinking: ${event.data.delta.content[0].payload.value}`); break; case "tool_call": console.log(`🔧 Tool call: ${event.data.name}(${JSON.stringify(event.data.arguments)})`); break; case "tool_result": console.log(`📊 Tool result: ${event.data.content.substring(0, 60)}...`); break; case "citation": console.log(`📑 Citation event: ${event.data}`); break; case "message": console.log(`💬 Message: ${event.data.delta.content[0].payload.value}`); break; case "final_answer": console.log(`✅ Final answer: ${event.data.generated_answer.substring(0, 100)}...`); console.log(` Citations: ${event.data.citations.length} sources referenced`); break; } } } ``` Example of streaming output: ```plaintext 🧠 Thinking: Analyzing the query about DeepSeek R1 implications... 🔧 Tool call: search_file_knowledge({"query":"DeepSeek R1 capabilities advancements"}) 📊 Tool result: DeepSeek-R1 is a reasoning-focused LLM that uses reinforcement learning... 🧠 Thinking: The search provides valuable information about DeepSeek R1's capabilities 🔧 Tool call: web_search({"query":"AI reasoning capabilities future development"}) 📊 Tool result: Advanced reasoning capabilities are considered a key milestone toward... 💬 Message: DeepSeek-R1 has several important implications for the future of AI development: 💬 Message: 1. **Reinforcement Learning as a Key Approach**: DeepSeek-R1's success demonstrates... ✅ Final answer: DeepSeek-R1 has several important implications for the future of AI development...

This flexibility allows you to experiment with different state of the art strategies and optimize retrieval for specific use cases. **This cookbook will cover toggling between vanilla RAG, [HyDE](https://arxiv.org/abs/2212.10496) and [RAG-Fusion](https://arxiv.org/abs/2402.03367).**. Advanced RAG techniques are still a beta feature in R2R. They are not currently supported in agentic workflows and there may be limitations in observability and analytics when implementing them. Are we missing an important RAG technique? If so, then please let us know at founders@sciphi.ai. ## Supported Advanced RAG Techniques R2R currently supports two advanced RAG techniques: 1. **HyDE (Hypothetical Document Embeddings)**: Enhances retrieval by generating and embedding hypothetical documents based on the query. 2. **RAG-Fusion**: Improves retrieval quality by combining results from multiple search iterations. ## Using Advanced RAG Techniques You can specify which advanced RAG technique to use by setting the `search_strategy` parameter in your vector search settings. Below is a comprehensive overview of techniques supported by R2R. ### HyDE #### What is HyDE? HyDE is an innovative approach that supercharges dense retrieval, especially in zero-shot scenarios. Here's how it works: 1. **Query Expansion**: HyDE uses a Language Model to generate hypothetical answers or documents based on the user's query. 2. **Enhanced Embedding**: These hypothetical documents are embedded, creating a richer semantic search space. 3. **Similarity Search**: The embeddings are used to find the most relevant actual documents in your database. 4. **Informed Generation**: The retrieved documents and original query are used to generate the final response. #### Implementation Diagram The diagram which follows below illustrates the HyDE flow which fits neatly into the schema of our diagram above (note, the GraphRAG workflow is omitted for brevity): ```mermaid graph TD A[User Query] --> B[QueryTransformPipe] B -->|Generate Hypothetical Documents| C[MultiSearchPipe] C --> D[VectorSearchPipe] D --> E[RAG Generation] A --> E F[Document DB] --> D subgraph HyDE Process B --> G[Hypothetical Doc 1] B --> H[Hypothetical Doc 2] B --> I[Hypothetical Doc n] G --> J[Embed] H --> J I --> J J --> C end subgraph Vector Search D --> K[Similarity Search] K --> L[Rank Results] L --> E end C --> |Multiple Searches| D K --> |Retrieved Documents| L ``` #### Using HyDE in R2R ```python client.retrieval.rag( "What are the main themes in the DeepSeek paper?", search_settings={ "search_strategy": "hyde", "limit": 10 } ) ``` ```plaintext RAGResponse( generated_answer='DeepSeek-R1 is a model that demonstrates impressive performance across various tasks, leveraging reinforcement learning (RL) and supervised fine-tuning (SFT) to enhance its capabilities. It excels in writing tasks, open-domain question answering, and benchmarks like IF-Eval, AlpacaEval2.0, and ArenaHard [1], [2]. DeepSeek-R1 outperforms its predecessor, DeepSeek-V3, in several areas, showcasing its strengths in reasoning and generalization across diverse domains [1]. It also achieves competitive results on factual benchmarks like SimpleQA, although it performs worse on the Chinese SimpleQA benchmark due to safety RL constraints [2]. Additionally, DeepSeek-R1 is involved in distillation processes to transfer its reasoning capabilities to smaller models, which perform exceptionally well on benchmarks [4], [6]. The model is optimized for English and Chinese, with plans to address language mixing issues in future updates [8].', search_results=AggregateSearchResult( chunk_search_results=[ChunkSearchResult(score=0.643, text=Document Title: DeepSeek_R1.pdf ...)] ), citations=[Citation(index=1, rawIndex=1, startIndex=305, endIndex=308, snippetStartIndex=288, snippetEndIndex=315, sourceType='chunk', id='e760bb76-1c6e-52eb-910d-0ce5b567011b', document_id='e43864f5-a36f-548e-aacd-6f8d48b30c7f', owner_id='2acb499e-8428-543b-bd85-0d9098718220', collection_ids=['122fdf6a-e116-546b-a8f6-e4cb2e2c0a09'], score=0.6433466439465674, text='Document Title: DeepSeek_R1.pdf\n\nText: could achieve an accuracy of over 70%.\nDeepSeek-R1 also delivers impressive results on IF-Eval, a benchmark designed to assess a\nmodels ability to follow format instructions.

RAG-Fusion is an advanced technique that combines Retrieval-Augmented Generation (RAG) with Reciprocal Rank Fusion (RRF) to improve the quality and relevance of retrieved information. Here's how it works: 1. **Query Expansion**: The original query is used to generate multiple related queries, providing different perspectives on the user's question. 2. **Multiple Retrievals**: Each generated query is used to retrieve relevant documents from the database. 3. **Reciprocal Rank Fusion**: The retrieved documents are re-ranked using the RRF algorithm, which combines the rankings from multiple retrieval attempts. 4. **Enhanced RAG**: The re-ranked documents, along with the original and generated queries, are used to generate the final response. This approach helps to capture a broader context and potentially more relevant information compared to traditional RAG. #### Implementation Diagram Here's a diagram illustrating the RAG-Fusion workflow (again, we omit the graph process for brevity): ```mermaid graph TD A[User Query] --> B[QueryTransformPipe] B -->|Generate Multiple Queries| C[MultiSearchPipe] C --> D[VectorSearchPipe] D --> E[RRF Reranking] E --> F[RAG Generation] A --> F G[Document DB] --> D subgraph RAG-Fusion Process B --> H[Generated Query 1] B --> I[Generated Query 2] B --> J[Generated Query n] H --> C I --> C J --> C end subgraph Vector Search D --> K[Search Results 1] D --> L[Search Results 2] D --> M[Search Results n] K --> E L --> E M --> E end E --> |Re-ranked Documents| F ``` #### Using RAG-Fusion in R2R ```python rag_fusion_response = client.retrieval.rag( "What are the main themes in DeepSeeks paper?", search_settings={ "search_strategy": "rag_fusion", "limit": 20 } ) ``` ### Combining with Other Settings You can readily combine these advanced techniques with other search and RAG settings: ```python custom_rag_response = client.retrieval.rag( "What are the main themes in the DeepSeek paper?", search_settings={ "search_strategy": "hyde", "limit": 15, "use_hybrid_search": True }, rag_generation_config={ "model": "anthropic/claude-3-opus-20240229", "temperature": 0.7 } ) ``` ## Conclusion By leveraging these advanced RAG techniques and customizing their underlying prompts, you can significantly enhance the quality and relevance of your retrieval and generation processes. Experiment with different strategies, settings, and prompt variations to find the optimal configuration for your specific use case. The flexibility of R2R allows you to iteratively improve your system's performance and adapt to changing requirements. ================================================ FILE: docs/documentation/retrieval/agentic-rag.md ================================================ ## Introduction R2R's **Agentic RAG** orchestrates multi-step reasoning with Retrieval-Augmented Generation (RAG). By pairing large language models with advanced retrieval and tool integrations, the agent can fetch relevant data from the internet, your documents and knowledge graphs, reason over it, and produce robust, context-aware answers. Agentic RAG (also called Deep Research) is an extension of R2R's basic retrieval functionality. If you are new to R2R, we suggest starting with the [Quickstart](/documentation/quickstart) and [Search & RAG](/documentation/search-and-rag) docs first. ## Key Features The agent can chain multiple actions, like searching documents or referencing conversation history, before generating its final response. Integrates with R2R's vector, full-text, or hybrid search to gather the most relevant context for each query. Maintain dialogue across multiple turns by including conversation_id in each request. Dynamically invoke tools at runtime to gather and analyze information from various sources. ## Available Modes The Agentic RAG system offers two primary operating modes: ### RAG Mode (Default) Standard retrieval-augmented generation for answering questions based on your knowledge base: - Semantic and hybrid search capabilities - Document-level and chunk-level content retrieval - Optional web search integrations, leveraging Serper and Firecrawl - Source citation and evidence-based responses ### Research Mode Advanced capabilities for deep analysis, reasoning, and computation: - All RAG mode capabilities - A dedicated reasoning system for complex problem-solving - Critique capabilities to identify potential biases or logical fallacies - Python execution for computational analysis - Multi-step reasoning for deeper exploration of topics ## Available Tools ### RAG Tools The agent can use the following tools in RAG mode: | Tool Name | Description | Dependencies | |-----------|-------------|-------------| | `search_file_knowledge` | Semantic/hybrid search on your ingested documents using R2R's search capabilities | None | | `search_file_descriptions` | Search over file-level metadata (titles, doc-level descriptions) | None | | `get_file_content` | Fetch entire documents or chunk structures for deeper analysis | None | | `web_search` | Query external search APIs for up-to-date information | Requires `SERPER_API_KEY` environment variable ([serper.dev](https://serper.dev/)) | | `web_scrape` | Scrape and extract content from specific web pages | Requires `FIRECRAWL_API_KEY` environment variable ([firecrawl.dev](https://www.firecrawl.dev/)) | ### Research Tools The agent can use the following tools in Research mode: | Tool Name | Description | Dependencies | |-----------|-------------|-------------| | `rag` | Leverage the underlying RAG agent to perform information retrieval and synthesis | None | | `reasoning` | Call a dedicated model for complex analytical thinking | None | | `critique` | Analyze conversation history to identify flaws, biases, and alternative approaches | None | | `python_executor` | Execute Python code for complex calculations and analysis | None | ## Basic Usage Below are examples of how to use the agent for both single-turn queries and multi-turn conversations. ```python from r2r import R2RClient from r2r import ( ThinkingEvent, ToolCallEvent, ToolResultEvent, CitationEvent, MessageEvent, FinalAnswerEvent, ) # when using auth, do client.users.login(...) # Basic RAG mode with streaming response = client.retrieval.agent( message={ "role": "user", "content": "What does DeepSeek R1 imply for the future of AI?" }, rag_generation_config={ "model": "anthropic/claude-3-7-sonnet-20250219", "extended_thinking": True, "thinking_budget": 4096, "temperature": 1, "top_p": None, "max_tokens_to_sample": 16000, "stream": True }, rag_tools=["search_file_knowledge", "get_file_content"], mode="rag" ) # Improved streaming event handling current_event_type = None for event in response: # Check if the event type has changed event_type = type(event) if event_type != current_event_type: current_event_type = event_type print() # Add newline before new event type # Print emoji based on the new event type if isinstance(event, ThinkingEvent): print(f"\n🧠 Thinking: ", end="", flush=True) elif isinstance(event, ToolCallEvent): print(f"\n🔧 Tool call: ", end="", flush=True) elif isinstance(event, ToolResultEvent): print(f"\n📊 Tool result: ", end="", flush=True) elif isinstance(event, CitationEvent): print(f"\n📑 Citation: ", end="", flush=True) elif isinstance(event, MessageEvent): print(f"\n💬 Message: ", end="", flush=True) elif isinstance(event, FinalAnswerEvent): print(f"\n✅ Final answer: ", end="", flush=True) # Print the content without the emoji if isinstance(event, ThinkingEvent): print(f"{event.data.delta.content[0].payload.value}", end="", flush=True) elif isinstance(event, ToolCallEvent): print(f"{event.data.name}({event.data.arguments})") elif isinstance(event, ToolResultEvent): print(f"{event.data.content[:60]}...") elif isinstance(event, CitationEvent): print(f"{event.data}") elif isinstance(event, MessageEvent): print(f"{event.data.delta.content[0].payload.value}", end="", flush=True) elif isinstance(event, FinalAnswerEvent): print(f"{event.data.generated_answer[:100]}...") print(f" Citations: {len(event.data.citations)} sources referenced") ``` ```javascript const { r2rClient } = require("r2r-js");

This includes: - Filters to restrict document sources - Limits on the number of results - Hybrid search configuration - Collection restrictions ```python # Using search settings with the agent response = client.retrieval.agent( message={"role": "user", "content": "Summarize our Q1 financial results"}, search_settings={ "use_semantic_search": True, "filters": {"collection_ids": {"$overlap": ["e43864f5-..."]}}, "limit": 25 }, rag_tools=["search_file_knowledge", "get_file_content"], mode="rag" ) ``` ### Model Selection and Parameters You can customize the agent's behavior by selecting different models and adjusting generation parameters: ```python # Using a specific model with custom parameters response = client.retrieval.agent( message={"role": "user", "content": "Write a concise summary of DeepSeek R1's capabilities"}, rag_generation_config={ "model": "anthropic/claude-3-haiku-20240307", # Faster model for simpler tasks "temperature": 0.3, # Lower temperature for more deterministic output "max_tokens_to_sample": 500, # Limit response length "stream": False # Non-streaming for simpler use cases }, mode="rag" ) ``` ## Multi-Turn Conversations You can maintain context across multiple turns using `conversation_id`. The agent will remember previous interactions and build upon them in subsequent responses. ```python # Create a new conversation conversation = client.conversations.create() conversation_id = conversation.results.id # First turn first_response = client.retrieval.agent( message={"role": "user", "content": "What does DeepSeek R1 imply for the future of AI?"}, rag_generation_config={ "model": "anthropic/claude-3-7-sonnet-20250219", "temperature": 0.7, "max_tokens_to_sample": 1000, "stream": False }, conversation_id=conversation_id, mode="rag" ) print(f"First response: {first_response.results.messages[-1].content[:100]}...") # Follow-up query in the same conversation follow_up_response = client.retrieval.agent( message={"role": "user", "content": "How does it compare to other reasoning models?"}, rag_generation_config={ "model": "anthropic/claude-3-7-sonnet-20250219", "temperature": 0.7, "max_tokens_to_sample": 1000, "stream": False }, conversation_id=conversation_id, mode="rag" ) print(f"Follow-up response: {follow_up_response.results.messages[-1].content[:100]}...") # The agent maintains context, so it knows "it" refers to DeepSeek R1 ``` ```javascript // Create a new conversation const conversation = await client.conversations.create(); const conversationId = conversation.results.id; // First turn const firstResponse = await client.retrieval.agent({ message: { role: "user", content: "What does DeepSeek R1 imply for the future of AI?" }, ragGenerationConfig: { model: "anthropic/claude-3-7-sonnet-20250219", temperature: 0.7, maxTokens: 1000, stream: false }, conversationId: conversationId, mode: "rag" }); console.log(`First response: ${firstResponse.results.messages[firstResponse.results.messages.length - 1].content.substring(0, 100)}...`); // Follow-up query in the same conversation const followUpResponse = await client.retrieval.agent({ message: { role: "user", content: "How does it compare to other reasoning models?" }, ragGenerationConfig: { model: "anthropic/claude-3-7-sonnet-20250219", temperature: 0.7, maxTokens: 1000, stream: false }, conversationId: conversationId, mode: "rag" }); console.log(`Follow-up response: ${followUpResponse.results.messages[followUpResponse.results.messages.length - 1].content.substring(0, 100)}...`); // The agent maintains context, so it knows "it" refers to DeepSeek R1 ``` ## Performance Considerations Based on our integration testing, here are some considerations to optimize your agent usage: ### Response Time Management Response times vary based on the complexity of the query, the number of tools used, and the length of the requested output: ```python # For time-sensitive applications, consider: # 1. Using a smaller max_tokens value # 2. Selecting faster models like claude-3-haiku # 3. Avoiding unnecessary tools fast_response = client.retrieval.agent( message={"role": "user", "content": "Give me a quick overview of DeepSeek R1"}, rag_generation_config={ "model": "anthropic/claude-3-haiku-20240307", # Faster model "max_tokens_to_sample": 200, # Limited output "stream": True # Stream for perceived responsiveness }, rag_tools=["search_file_knowledge"], # Minimal tools mode="rag" ) ``` ### Handling Large Context The agent can process large document contexts efficiently, but performance can be improved by using appropriate filters: ```python # When working with large document collections, use filters to narrow results filtered_response = client.retrieval.agent( message={"role": "user", "content": "Summarize key points from our AI ethics documentation"}, search_settings={ "filters": { "$and": [ {"document_type": {"$eq": "pdf"}}, {"metadata.category": {"$eq": "ethics"}}, {"metadata.year": {"$gt": 2023}} ] }, "limit": 10 # Limit number of chunks returned }, rag_generation_config={ "max_tokens_to_sample": 500, "stream": True }, mode="rag" ) ``` ## How Tools Work (Under the Hood) R2R's Agentic RAG leverages a powerful toolset to conduct comprehensive research: ### RAG Mode Tools - **search_file_knowledge**: Looks up relevant text chunks and knowledge graph data from your ingested documents using semantic and hybrid search capabilities. - **search_file_descriptions**: Searches over file-level metadata (titles, doc-level descriptions) rather than chunk content. - **get_file_content**: Fetches entire documents or their chunk structures for deeper analysis when the agent needs more comprehensive context. - **web_search**: Queries external search APIs (like Serper or Google) for live, up-to-date information from the internet. Requires a `SERPER_API_KEY` environment variable. - **web_scrape**: Uses Firecrawl to extract content from specific web pages for in-depth analysis. Requires a `FIRECRAWL_API_KEY` environment variable. ### Research Mode Tools - **rag**: A specialized research tool that utilizes the underlying RAG agent to perform comprehensive information retrieval and synthesis across your data sources. - **python_executor**: Executes Python code for complex calculations, statistical operations, and algorithmic implementations, giving the agent computational capabilities. - **reasoning**: Allows the research agent to call a dedicated model as an external module for complex analytical thinking. - **critique**: Analyzes conversation history to identify potential flaws, biases, and alternative approaches to improve research rigor. The Agent is built on a sophisticated architecture that combines these tools with streaming capabilities and flexible response formats. It can decide which tools to use based on the query requirements and can dynamically invoke them during the research process. ## Conclusion Agentic RAG provides a powerful approach to retrieval-augmented generation. By combining **advanced search**, **multi-step reasoning**, **conversation context**, and **dynamic tool usage**, the agent helps you build sophisticated Q&A or research solutions on your R2R-ingested data. ================================================ FILE: docs/documentation/retrieval/hybrid-search.md ================================================ ## Introduction R2R's hybrid search blends keyword-based full-text search with semantic vector search, delivering results that are both contextually relevant and precise. By unifying these approaches, hybrid search excels at handling complex queries where both exact terms and overall meaning matter. ## How R2R Hybrid Search Works ### Full-Text Search Leverages Postgres's `ts_rank_cd` and `websearch_to_tsquery` to find documents containing your keywords. ### Semantic Search Uses vector embeddings to locate documents contextually related to your query, even if they don't share exact keywords. ### Reciprocal Rank Fusion (RRF) Merges results from both full-text and semantic searches using a formula like: $$\text{COALESCE}\left(\frac{1.0}{\text{rrf\_k} + \text{full\_text.rank\_ix}}, 0.0\right) \cdot \text{full\_text\_weight} + \text{COALESCE}\left(\frac{1.0}{\text{rrf\_k} + \text{semantic.rank\_ix}}, 0.0\right) \cdot \text{semantic\_weight}$$ This ensures that documents relevant both semantically and by keyword ranking float to the top. ### Result Ranking Orders the final set of results based on the combined RRF score, providing balanced, meaningful search outcomes. ## Key Features ### Full-Text Search - Uses Postgres indexing and querying for quick, exact term matches. - Great for retrieving documents where specific terminology is critical. ### Semantic Search - Embeds queries and documents into vector representations. - Finds documents related to the query's meaning, not just its wording. ### Hybrid Integration - By enabling both `use_fulltext_search` and `use_semantic_search`, or choosing the `advanced` mode, you get the best of both worlds. - RRF blends these results, ensuring that documents align with the query's intent and exact terms where needed. ## Understanding Search Modes R2R supports multiple search modes that can simplify or customize the configuration for you: - **`basic`**: Primarily semantic search. Suitable for straightforward scenarios where semantic understanding is key, but you don't need the additional context of keyword matching. - **`advanced`**: Combines semantic and full-text search by default, effectively enabling hybrid search with well-tuned default parameters. Ideal if you want the benefits of hybrid search without manual configuration. - **`custom`**: Allows you full control over the search settings, including toggling semantic and full-text search independently. Choose this if you want to fine-tune weights, limits, and other search behaviors. When using `advanced` mode, R2R automatically configures hybrid search for you. For `custom` mode, you can directly set `use_hybrid_search=True` or enable both `use_semantic_search` and `use_fulltext_search` to achieve a hybrid search setup. ## Configuration **Choosing a Search Mode:** - `basic`: Semantic-only. ```python search_mode = "basic" # Semantic search only, no full-text matching ``` - `advanced`: Hybrid by default. ```python search_mode = "advanced" # Hybrid search is automatically enabled with well-tuned defaults ``` - `custom`: Manually configure hybrid search. ```python search_mode = "custom" # Enable both semantic and full-text search and set weights as needed: search_settings = { "use_semantic_search": True, "use_fulltext_search": True, "use_hybrid_search": True, "hybrid_settings": { "full_text_weight": 1.0, "semantic_weight": 5.0, "full_text_limit": 200, "rrf_k": 50 } } ``` For more details on runtime configuration and combining `search_mode` with custom `search_settings`, refer to the Search API documentation. ## Best Practices 1. **Optimize Database and Embeddings**: Ensure Postgres indexing and vector store configurations are optimal for performance. 2. **Adjust Weights and Limits**: Tweak `full_text_weight`, `semantic_weight`, and `rrf_k` values when using `custom` mode. If you're using `advanced` mode, the defaults are already tuned for general use cases. 3. **Regular Updates**: Keep embeddings and indexes up-to-date to maintain search quality. 4. **Choose Appropriate Embeddings**: Select an embedding model that fits your content domain for the best semantic results. ## Conclusion R2R's hybrid search delivers robust, context-aware retrieval by merging semantic and keyword-driven approaches. Whether you pick `basic` mode for simplicity, `advanced` mode for out-of-the-box hybrid search, or `custom` mode for granular control, R2R ensures you can tailor the search experience to your unique needs. ================================================ FILE: docs/documentation/retrieval/search-and-rag.md ================================================ R2R provides powerful search and retrieval capabilities through vector search, full-text search, hybrid search, and Retrieval-Augmented Generation (RAG). The system supports multiple search modes and extensive runtime configuration to help you find and contextualize information effectively. Refer to the retrieval API and SDK reference for detailed retrieval examples. ## Search Modes and Settings When using the Search (`/retrieval/search`) or RAG (`/retrieval/rag`) endpoints, you control the retrieval process using `search_mode` and `search_settings`. * **`search_mode`** (Optional, defaults to `custom`): Choose between pre-configured modes or full customization. * `basic`: Defaults to a simple semantic search configuration. Good for quick setup. * `advanced`: Defaults to a hybrid search configuration combining semantic and full-text. Offers broader results. * `custom`: Allows full control via the `search_settings` object. If `search_settings` are omitted in `custom` mode, default vector search settings are applied. * **`search_settings`** (Optional): A detailed configuration object. If provided alongside `basic` or `advanced` modes, these settings will override the mode's defaults. Key settings include: * `use_semantic_search`: Boolean to enable/disable vector-based semantic search (default: `true` unless overridden). * `use_fulltext_search`: Boolean to enable/disable keyword-based full-text search (default: `false` unless using hybrid). * `use_hybrid_search`: Boolean to enable hybrid search, combining semantic and full-text (default: `false`). Requires `hybrid_settings`. * `filters`: Apply complex filtering rules using MongoDB-like syntax (see "Advanced Filtering" below). * `limit`: Integer controlling the maximum number of results to return (default: `10`). * `hybrid_settings`: Object to configure weights (`semantic_weight`, `full_text_weight`), limits (`full_text_limit`), and fusion (`rrf_k`) for hybrid search. * `chunk_settings`: Object to fine-tune vector index parameters like `index_measure` (distance metric), `probes`, `ef_search`. * `search_strategy`: String to enable advanced RAG techniques like `"hyde"` or `"rag_fusion"` (default: `"vanilla"`). See [Advanced RAG](/documentation/advanced-rag). * `include_scores`: Boolean to include relevance scores in the results (default: `true`). * `include_metadatas`: Boolean to include metadata in the results (default: `true`). ## AI Powered Search (`/retrieval/search`) R2R offers powerful and highly configurable search capabilities. This endpoint returns raw search results without LLM generation. ### Basic Search Example This performs a search using default configurations or a specified mode. ```python # Uses default settings (likely semantic search in 'custom' mode) results = client.retrieval.search( query="What is DeepSeek R1?", ) # Explicitly using 'basic' mode results_basic = client.retrieval.search( query="What is DeepSeek R1?", search_mode="basic", ) ``` ```javascript // Uses default settings const results = await client.retrieval.search({ query: "What is DeepSeek R1?", }); // Explicitly using 'basic' mode const resultsBasic = await client.retrieval.search({ query: "What is DeepSeek R1?", searchMode: "basic", }); ``` ```bash # Uses default settings curl -X POST "https://api.sciphi.ai/v3/retrieval/search" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "query": "What is DeepSeek R1?" }' # Explicitly using 'basic' mode curl -X POST "https://api.sciphi.ai/v3/retrieval/search" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "query": "What is DeepSeek R1?", "search_mode": "basic" }' ``` **Response Structure (`WrappedSearchResponse`):** The search endpoint returns a `WrappedSearchResponse` containing an `AggregateSearchResult` object with fields like: * `results.chunk_search_results`: A list of relevant text `ChunkSearchResult` objects found (containing `id`, `document_id`, `text`, `score`, `metadata`). * `results.graph_search_results`: A list of relevant `GraphSearchResult` objects (entities, relationships, communities) if graph search is active and finds results. * `results.web_search_results`: A list of `WebSearchResult` objects (if web search was somehow enabled, though typically done via RAG/Agent). ```json // Simplified Example Structure { "results": { "chunk_search_results": [ { "score": 0.643, "text": "Document Title: DeepSeek_R1.pdf...", "id": "chunk-uuid-...", "document_id": "doc-uuid-...", "metadata": { ... } }, // ... more chunks ], "graph_search_results": [ // Example: An entity result if graph search ran { "id": "graph-entity-uuid...", "content": { "name": "DeepSeek-R1", "description": "A large language model...", "id": "entity-uuid..." }, "result_type": "ENTITY", "score": 0.95, "metadata": { ... } } // ... potentially relationships or communities ], "web_search_results": [] } } ``` ### Hybrid Search Example Combine keyword-based (full-text) search with vector search for potentially broader results. ```python hybrid_results = client.retrieval.search( query="What was Uber's profit in 2020?", search_settings={ "use_hybrid_search": True, "hybrid_settings": { "full_text_weight": 1.0, "semantic_weight": 5.0, "full_text_limit": 200, # How many full-text results to initially consider "rrf_k": 50, # Parameter for Reciprocal Rank Fusion }, "filters": {"metadata.title": {"$in": ["uber_2021.pdf"]}}, # Filter by metadata field "limit": 10 # Final number of results after fusion/ranking }, ) ``` ```javascript const hybridResults = await client.retrieval.search({ query: "What was Uber's profit in 2020?", searchSettings: { useHybridSearch: true, hybridSettings: { fullTextWeight: 1.0, semanticWeight: 5.0, fullTextLimit: 200, rrfK: 50 // Assuming camelCase mapping in JS SDK }, filters: {"metadata.title": {"$in": ["uber_2021.pdf"]}}, limit: 10 }, }); ``` ```bash curl -X POST "https://api.sciphi.ai/v3/retrieval/search" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "query": "What was Uber'\''s profit in 2020?", "search_settings": { "use_hybrid_search": true, "hybrid_settings": { "full_text_weight": 1.0, "semantic_weight": 5.0, "full_text_limit": 200, "rrf_k": 50 }, "filters": {"metadata.title": {"$in": ["uber_2021.pdf"]}}, "limit": 10, "chunk_settings": { "index_measure": "l2_distance" } } }' ``` ### Advanced Filtering Apply filters to narrow search results based on document properties or metadata. Supported operators include `$eq`, `$neq`, `$gt`, `$gte`, `$lt`, `$lte`, `$like`, `$ilike`, `$in`, `$nin`. You can combine filters using `$and` and `$or`. ```python filtered_results = client.retrieval.search( query="What are the effects of climate change?", search_settings={ "filters": { "$and":[ {"document_type": {"$eq": "pdf"}}, # Assuming 'document_type' is stored {"metadata.year": {"$gt": 2020}} # Access nested metadata fields ] }, "limit": 10 } ) ``` ```javascript const filteredResults = await client.retrieval.search({ query: "What are the effects of climate change?", searchSettings: { filters: { $and: [ {document_type: {$eq: "pdf"}}, {"metadata.year": {$gt: 2020}} ] }, limit: 10 } }); ``` ### Distance Measures for Vector Search Distance metrics for vector search, which can be configured through the `chunk_settings.index_measure` parameter. Choosing the right distance measure can significantly impact search quality depending on your embeddings and use case: * **`cosine_distance`** (Default): Measures the cosine of the angle between vectors, ignoring magnitude. Best for comparing documents regardless of their length. * **`l2_distance`** (Euclidean): Measures the straight-line distance between vectors. Useful when both direction and magnitude matter. * **`max_inner_product`**: Optimized for finding vectors with similar direction. Good for recommendation systems. * **`l1_distance`** (Manhattan): Measures the sum of absolute differences. Less sensitive to outliers than L2. * **`hamming_distance`**: Counts the positions at which vectors differ. Best for binary embeddings. * **`jaccard_distance`**: Measures dissimilarity between sample sets. Useful for sparse embeddings. ```python results = client.retrieval.search( query="What are the key features of quantum computing?", search_settings={ "chunk_settings": { "index_measure": "l2_distance" # Use Euclidean distance instead of default } } ) ``` For most text embedding models (e.g., OpenAI's models), cosine_distance is recommended. For specialized embeddings or specific use cases, experiment with different measures to find the optimal setting for your data. ## Knowledge Graph Enhanced Retrieval Beyond searching through text chunks, R2R can leverage knowledge graphs to enrich the retrieval process. This offers several benefits: * **Contextual Understanding:** Knowledge graphs store information as entities (like people, organizations, concepts) and relationships (like "works for", "is related to", "is a type of"). Searching the graph allows R2R to find connections and context that might be missed by purely text-based search. * **Relationship-Based Queries:** Answer questions that rely on understanding connections, such as "What projects is Person X involved in?" or "How does Concept A relate to Concept B?". * **Discovering Structure:** Graph search can reveal higher-level structures, such as communities of related entities or key connecting concepts within your data. * **Complementary Results:** Graph results (entities, relationships, community summaries) complement text chunks by providing structured information and broader context. When knowledge graph search is active within R2R, the `AggregateSearchResult` returned by the Search or RAG endpoints may include relevant items in the `graph_search_results` list, enhancing the context available for understanding or generation. ## Retrieval-Augmented Generation (RAG) (`/retrieval/rag`) R2R's RAG engine combines the search capabilities above (including text, vector, hybrid, and potentially graph results) with Large Language Models (LLMs) to generate contextually relevant responses grounded in your ingested documents and optional web search results. ### RAG Configuration (`rag_generation_config`) Control the LLM's generation process: * `model`: Specify the LLM to use (e.g., `"openai/gpt-4o-mini"`, `"anthropic/claude-3-haiku-20240307"`). Defaults are set in R2R config. * `stream`: Boolean (default `false`). Set to `true` for streaming responses. * `temperature`, `max_tokens`, `top_p`, etc.: Standard LLM generation parameters. ### Basic RAG Generate a response using retrieved context. Uses the same `search_mode` and `search_settings` as the search endpoint to find relevant information. ```python # Basic RAG call using default search and generation settings rag_response = client.retrieval.rag(query="What is DeepSeek R1?") ``` ```javascript // Basic RAG call using default settings const ragResponse = await client.retrieval.rag({ query: "What is DeepSeek R1?" }); ``` ```bash curl -X POST "https://api.sciphi.ai/v3/retrieval/rag" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "query": "What is DeepSeek R1?" }' ``` **Response Structure (`WrappedRAGResponse`):** The non-streaming RAG endpoint returns a `WrappedRAGResponse` containing an `RAGResponse` object with fields like: * `results.generated_answer`: The final synthesized answer from the LLM. * `results.search_results`: The `AggregateSearchResult` used to generate the answer (containing chunks, possibly graph results, and web results). * `results.citations`: A list of `Citation` objects linking parts of the answer to specific sources (`ChunkSearchResult`, `GraphSearchResult`, `WebSearchResult`, etc.) found in `search_results`. Each citation includes an `id` (short identifier used in the text like `[1]`) and a `payload` containing the source object. * `results.metadata`: LLM provider metadata about the generation call. ```json // Simplified Example Structure { "results": { "generated_answer": "DeepSeek-R1 is a model that... [1]. It excels in tasks... [2].", "search_results": { "chunk_search_results": [ { "id": "chunk-abc...", "text": "...", "score": 0.8 }, /* ... */ ], "graph_search_results": [ { /* Graph Entity/Relationship */ } ], "web_search_results": [ { "url": "...", "title": "...", "snippet": "..." }, /* ... */ ] }, "citations": [ { "id": "cit.1", // Corresponds to [1] in text "object": "citation", "payload": { /* ChunkSearchResult for chunk-abc... */ } }, { "id": "cit.2", // Corresponds to [2] in text "object": "citation", "payload": { /* WebSearchResult for relevant web page */ } } // ... more citations potentially linking to graph results too ], "metadata": { "model": "openai/gpt-4o-mini", ... } } } ``` ### RAG with Web Search Integration Enhance RAG responses with up-to-date information from the web by setting `include_web_search=True`. ```python web_rag_response = client.retrieval.rag( query="What are the latest developments with DeepSeek R1?", include_web_search=True ) ``` ```javascript const webRagResponse = await client.retrieval.rag({ query: "What are the latest developments with DeepSeek R1?", includeWebSearch: true // Use camelCase for JS SDK }); ``` ```bash curl -X POST "https://api.sciphi.ai/v3/retrieval/rag" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "query": "What are the latest developments with DeepSeek R1?", "include_web_search": true }' ``` When enabled, R2R performs a web search using the query, and the results are added to the context provided to the LLM alongside results from your documents or knowledge graph. ### RAG with Hybrid Search Combine hybrid search with RAG by configuring `search_settings`. ```python hybrid_rag_response = client.retrieval.rag( query="Who is Jon Snow?", search_settings={"use_hybrid_search": True} ) ``` ```javascript const hybridRagResponse = await client.retrieval.rag({ query: "Who is Jon Snow?", searchSettings: { useHybridSearch: true }, }); ``` ```bash # Correctly place use_hybrid_search in search_settings curl -X POST "https://api.sciphi.ai/v3/retrieval/rag" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "query": "Who is Jon Snow?", "search_settings": { "use_hybrid_search": true, "limit": 10 } }' ``` ### Streaming RAG Receive RAG responses as a stream of Server-Sent Events (SSE) by setting `stream: True` in `rag_generation_config`. This is ideal for real-time applications. **Event Types:** 1. `search_results`: Contains the initial `AggregateSearchResult` (sent once at the beginning). * `data`: The full `AggregateSearchResult` object (chunks, potentially graph results, web results). 2. `message`: Streams partial tokens of the response as they are generated. * `data.delta.content`: The text chunk being streamed. 3. `citation`: Indicates when a citation source is identified. Sent *once* per unique source when it's first referenced. * `data.id`: The short citation ID (e.g., `"cit.1"`). * `data.payload`: The full source object (`ChunkSearchResult`, `GraphSearchResult`, `WebSearchResult`, etc.). * `data.is_new`: True if this is the first time this citation ID is sent. * `data.span`: The start/end character indices in the *current* accumulated text where the citation marker (e.g., `[1]`) appears. 4. `final_answer`: Sent once at the end, containing the complete generated answer and structured citations. * `data.generated_answer`: The full final text. * `data.citations`: List of all citations, including their `id`, `payload`, and all `spans` where they appeared in the final text. ```python from r2r import ( CitationEvent, FinalAnswerEvent, MessageEvent, SearchResultsEvent, R2RClient, # Assuming ThinkingEvent is imported if needed, though not standard in basic RAG ) # Set stream=True in rag_generation_config result_stream = client.retrieval.rag( query="What is DeepSeek R1?", search_settings={"limit": 25}, rag_generation_config={"stream": True, "model": "openai/gpt-4o-mini"}, include_web_search=True, ) for event in result_stream: if isinstance(event, SearchResultsEvent): print(f"Search results received (Chunks: {len(event.data.data.chunk_search_results)}, Graph: {len(event.data.data.graph_search_results)}, Web: {len(event.data.data.web_search_results)})") elif isinstance(event, MessageEvent): # Access the actual text delta if event.data.delta and event.data.delta.content and event.data.delta.content[0].type == 'text' and event.data.delta.content[0].payload.value: print(event.data.delta.content[0].payload.value, end="", flush=True) elif isinstance(event, CitationEvent): # Payload is only sent when is_new is True if event.data.is_new: print(f"\n<<< New Citation Source Detected: ID={event.data.id} >>>") elif isinstance(event, FinalAnswerEvent): print("\n\n--- Final Answer ---") print(event.data.generated_answer) print("\n--- Citations Summary ---") for cit in event.data.citations: print(f" ID: {cit.id}, Spans: {cit.span}") ``` ```javascript // Set stream: true in ragGenerationConfig const resultStream = await client.retrieval.rag({ query: "What is DeepSeek R1?", searchSettings: { limit: 25 }, ragGenerationConfig: { stream: true, model: "openai/gpt-4o-mini" }, includeWebSearch: true, }); // Check if we got an async iterator (streaming) if (Symbol.asyncIterator in resultStream) { console.log("Starting stream processing..."); // Loop over each event from the server for await (const event of resultStream) { switch (event.event) { case "search_results": console.log(`\nSearch results received (Chunks: ${event.data.chunk_search_results?.length || 0}, Graph: ${event.data.graph_search_results?.length || 0}, Web: ${event.data.web_search_results?.length || 0})`); break; case "message": // Access the actual text delta if (event.data?.delta?.content?.[0]?.text?.value) { process.stdout.write(event.data.delta.content[0].text.value); } break; case "citation": // Payload only sent when is_new is true if (event.data?.is_new) { process.stdout.write(`\n<<< New Citation Source Detected: ID=${event.data.id} >>>`); // console.log(` Payload: ${JSON.stringify(event.data.payload)}`); // Can be verbose } else { // Citation already seen, no need to log payload again } break; case "final_answer": process.stdout.write("\n\n--- Final Answer ---\n"); console.log(event.data.generated_answer); console.log("\n--- Citations Summary ---"); event.data.citations?.forEach(cit => { console.log(` ID: ${cit.id}, Spans: ${JSON.stringify(cit.spans)}`); // console.log(` Payload: ${JSON.stringify(cit.payload)}`); // Can be verbose }); break; default: console.log("\nUnknown or unhandled event:", event.event); } } console.log("\nStream finished."); } else { // Handle non-streaming response if necessary (though we requested stream) console.log("Received non-streaming response:", resultStream); } ``` ### Customizing RAG Besides `search_settings`, you can customize RAG generation using `rag_generation_config`. Example of customizing the model with web search: ```python # Requires ANTHROPIC_API_KEY env var if using Anthropic models response = client.retrieval.rag( query="Who was Aristotle and what are his recent influences?", rag_generation_config={ "model":"anthropic/claude-3-haiku-20240307", "stream": False, # Get a single response object "temperature": 0.5 }, include_web_search=True ) print(response.results.generated_answer) ``` ```javascript // Requires ANTHROPIC_API_KEY env var if using Anthropic models const response = await client.retrieval.rag({ query: "Who was Aristotle and what are his recent influences?", ragGenerationConfig: { model: 'anthropic/claude-3-haiku-20240307', temperature: 0.5, stream: false // Get a single response object }, includeWebSearch: true }); console.log(response.results.generated_answer); ``` ```bash # Requires ANTHROPIC_API_KEY env var if using Anthropic models curl -X POST "https://api.sciphi.ai/v3/retrieval/rag" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "query": "Who was Aristotle and what are his recent influences?", "rag_generation_config": { "model": "anthropic/claude-3-haiku-20240307", "temperature": 0.5, "stream": false }, "include_web_search": true }' ``` ## Conclusion R2R's search and RAG capabilities provide flexible tools for finding and contextualizing information. Whether you need simple semantic search, advanced hybrid retrieval with filtering, or customizable RAG generation incorporating document chunks, knowledge graph insights, and web results via streaming or single responses, the system can be configured to meet your specific needs. ================================================ FILE: docs/introduction/guides/rag.md ================================================ # More about RAG **On this page** 1.

[How RAG works in R2R](#how-rag-works-in-r2r) 6. [Best Practices](#best-practices) RAG (Retrieval-Augmented Generation) combines the power of large language models with precise information retrieval from your own documents. When users ask questions, RAG first retrieves relevant information from your document collection, then uses this context to generate accurate, contextual responses. This ensures AI responses are both relevant and grounded in your specific knowledge base. ## Before you begin RAG in R2R has the following requirements: - A running R2R instance (local or deployed) - Access to an LLM provider (OpenAI, Anthropic, or local models) - Documents ingested into your R2R system - Basic configuration for document processing and embedding generation ## What is RAG? RAG operates in three main steps: 1. **Retrieval**: Finding relevant information from your documents 2. **Augmentation**: Adding this information as context for the AI 3. **Generation**: Creating responses using both the context and the AI's knowledge Benefits over traditional LLM applications: - More accurate responses based on your specific documents - Reduced hallucination by grounding answers in real content - Ability to work with proprietary or recent information - Better control over AI outputs ## Set up RAG with R2R To start using RAG in R2R: 1. Install and start R2R: ```bash pip install r2r r2r serve --docker ``` 2. Ingest your documents: ```bash r2r documents create --file-paths /path/to/your/documents ``` 3. Test basic RAG functionality: ```bash r2r retrieval rag --query="your question here" ``` ## Configure RAG settings R2R offers several ways to customize RAG behavior: ### Retrieval Settings ```python # Using hybrid search (combines semantic and keyword search) client.retrieval.rag( query="your question", vector_search_settings={"use_hybrid_search": True} ) # Adjusting number of retrieved chunks client.retrieval.rag( query="your question", vector_search_settings={"limit": 30} ) ``` ### Generation Settings ```python # Adjusting response style client.retrieval.rag( query="your question", rag_generation_config={ "temperature": 0.7, "model": "openai/gpt-4" } ) ``` ## How RAG works in R2R R2R's RAG implementation uses a sophisticated process: ### Document Processing - Documents are split into semantic chunks - Each chunk is embedded using AI models - Chunks are stored with metadata and relationships ### Retrieval Process - Queries are processed using hybrid search - Both semantic similarity and keyword matching are considered - Results are ranked by relevance scores ### Response Generation - Retrieved chunks are formatted as context - The LLM generates responses using this context - Citations and references can be included ### Advanced Features - GraphRAG for relationship-aware responses - Multi-step RAG for complex queries - Agent-based RAG for interactive conversations ## Best Practices ### Document Processing - Use appropriate chunk sizes (256-1024 tokens) - Maintain document metadata - Consider document relationships ### Query Optimization - Use hybrid search for better retrieval - Adjust relevance thresholds - Monitor and analyze search performance ### Response Generation - Balance temperature for creativity vs accuracy - Use system prompts for consistent formatting - Implement error handling and fallbacks ## Learn More For more detailed information, explore these resources: - [RAG Configuration Guide](../../self-hosting/configuration/retrieval/rag.md) - Advanced configuration options - [Search and RAG Documentation](../../documentation/retrieval/search-and-rag.md) - Complete search capabilities - [Quickstart Guide](../../documentation/getting-started/quickstart.md) - Get started with R2R - [System Architecture](../system.md) - Understand how RAG fits into R2R ================================================ FILE: docs/introduction/guides/what-is-r2r.md ================================================ # What is R2R? **On this page** 1.

The boys at the counter fell to sniggering. The innkeeper came down from the upper room, apparently on purpose to listen to the “funny fellow” and sat down at a little distance, yawning lazily, but with dignity. Evidently Marmeladov was a familiar figure here, and he had most likely acquired his weakness for high-flown speeches from the habit of frequently entering into conversation with strangers of all sorts in the tavern. This habit develops into a necessity in some drunkards, and especially in those who are looked after sharply and kept in order at home. Hence in the company of other drinkers they try to justify themselves and even if possible obtain consideration. “Funny fellow!” pronounced the innkeeper. “And why don’t you work, why aren’t you at your duty, if you are in the service?” “Why am I not at my duty, honoured sir,” Marmeladov went on, addressing himself exclusively to Raskolnikov, as though it had been he who put that question to him. “Why am I not at my duty? Does not my heart ache to think what a useless worm I am? A month ago when Mr. Lebeziatnikov beat my wife with his own hands, and I lay drunk, didn’t I suffer?

He went rapidly up the stairs, walked into his unlocked room and at once fastened the latch. Then in senseless terror he rushed to the corner, to that hole under the paper where he had put the things; put his hand in, and for some minutes felt carefully in the hole, in every crack and fold of the paper. Finding nothing, he got up and drew a deep breath. ================================================ FILE: js/sdk/examples/data/sonia.txt ================================================ On the canal bank near the bridge and not two houses away from the one where Sonia lodged, there was a crowd of people, consisting principally of gutter children. The hoarse broken voice of Katerina Ivanovna could be heard from the bridge, and it certainly was a strange spectacle likely to attract a street crowd. Katerina Ivanovna in her old dress with the green shawl, wearing a torn straw hat, crushed in a hideous way on one side, was really frantic. She was exhausted and breathless. Her wasted consumptive face looked more suffering than ever, and indeed out of doors in the sunshine a consumptive always looks worse than at home. But her excitement did not flag, and every moment her irritation grew more intense. She rushed at the children, shouted at them, coaxed them, told them before the crowd how to dance and what to sing, began explaining to them why it was necessary, and driven to desperation by their not understanding, beat them.... Then she would make a rush at the crowd; if she noticed any decently dressed person stopping to look, she immediately appealed to him to see what these children “from a genteel, one may say aristocratic, house” had been brought to. If she heard laughter or jeering in the crowd, she would rush at once at the scoffers and begin squabbling with them. Some people laughed, others shook their heads, but everyone felt curious at the sight of the madwoman with the frightened children. The frying-pan of which Lebeziatnikov had spoken was not there, at least Raskolnikov did not see it. But instead of rapping on the pan, Katerina Ivanovna began clapping her wasted hands, when she made Lida and Kolya dance and Polenka sing. She too joined in the singing, but broke down at the second note with a fearful cough, which made her curse in despair and even shed tears. What made her most furious was the weeping and terror of Kolya and Lida. Some effort had been made to dress the children up as street singers are dressed. The boy had on a turban made of something red and white to look like a Turk. There had been no costume for Lida; she simply had a red knitted cap, or rather a night cap that had belonged to Marmeladov, decorated with a broken piece of white ostrich feather, which had been Katerina Ivanovna’s grandmother’s and had been preserved as a family possession. Polenka was in her everyday dress; she looked in timid perplexity at her mother, and kept at her side, hiding her tears. She dimly realised her mother’s condition, and looked uneasily about her. She was terribly frightened of the street and the crowd. Sonia followed Katerina Ivanovna, weeping and beseeching her to return home, but Katerina Ivanovna was not to be persuaded. ================================================ FILE: js/sdk/examples/data/zametov.txt ================================================ “How he keeps on! Are you afraid of having let out some secret? Don’t worry yourself; you said nothing about a countess. But you said a lot about a bulldog, and about ear-rings and chains, and about Krestovsky Island, and some porter, and Nikodim Fomitch and Ilya Petrovitch, the assistant superintendent. And another thing that was of special interest to you was your own sock. You whined, ‘Give me my sock.’ Zametov hunted all about your room for your socks, and with his own scented, ring-bedecked fingers he gave you the rag. And only then were you comforted, and for the next twenty-four hours you held the wretched thing in your hand; we could not get it from you. It is most likely somewhere under your quilt at this moment. And then you asked so piteously for fringe for your trousers. We tried to find out what sort of fringe, but we could not make it out. Now to business! Here are thirty-five roubles; I take ten of them, and shall give you an account of them in an hour or two. I will let Zossimov know at the same time, though he ought to have been here long ago, for it is nearly twelve. And you, Nastasya, look in pretty often while I am away, to see whether he wants a drink or anything else. And I will tell Pashenka what is wanted myself.

[Conclusion](#conclusion-19) --- ## Introduction **R2R** (Retrieval to Riches) is an engine for building user-facing **Retrieval-Augmented Generation (RAG)** applications. It provides core services through an architecture of providers, services, and an integrated RESTful API. This documentation offers a detailed walkthrough of interacting with R2R, including installation, configuration, and leveraging its advanced features such as data ingestion, search, RAG, and knowledge graphs. For a deeper dive into the R2R system architecture, refer to the [R2R System Architecture](https://r2r-docs.sciphi.ai/introduction/system). --- ## Installation Before diving into R2R's features, ensure that you have completed the [installation instructions](https://r2r-docs.sciphi.ai/documentation/installation/overview). ### Prerequisites - **Python 3.8+**: Ensure Python is installed on your system. - **Docker**: Required for Docker-based installations. Install Docker from the [official Docker installation guide](https://docs.docker.com/engine/install/). - **pip**: Python package installer. ### Docker Installation This installation guide is for the **Full R2R**. For solo developers or teams prototyping, start with [R2R Light](https://r2r-docs.sciphi.ai/documentation/installation/light/local-system). #### Install the R2R CLI & Python SDK ```bash pip install r2r ``` > **Note**: A distinct CLI binary for R2R is under active development. For specific needs or feature requests, reach out to the R2R team. #### Start R2R with Docker The Full R2R installation uses a custom configuration (`full.toml`). Launch R2R with Docker: ```bash r2r serve --docker --config-path=full.toml ``` > This command pulls necessary Docker images and starts required containers, including R2R, Hatchet, and Postgres+pgvector. Access the live server at [http://localhost:7272](http://localhost:7272/). ### Google Cloud Platform Deployment Deploying R2R on Google Cloud Platform (GCP) involves setting up a Compute Engine instance, installing dependencies, and configuring port forwarding. #### Overview 1. **Creating a Google Compute Engine Instance** 2. **Installing Dependencies** 3. **Setting up R2R** 4. **Configuring Port Forwarding for Local Access** 5. **Exposing Ports for Public Access (Optional)** 6. **Security Considerations** #### Creating a Google Compute Engine Instance 1. **Log in** to the Google Cloud Console. 2.

The application is accessible locally via SSH tunneling and optionally publicly. Ensure proper security measures are in place before exposing R2R to the internet. For more details, refer to the [R2R Configuration Documentation](https://r2r-docs.sciphi.ai/documentation/configuration/overview). --- ## R2R Application Lifecycle R2R's application lifecycle encompasses customization, configuration, deployment, implementation, and interaction. The lifecycle is designed to provide flexibility and scalability for various use cases. ### Developer Workflow - **Customize**: Developers tailor R2R applications using R2RConfig and the R2R SDK. - **Configure**: Adjust settings via configuration files (`r2r.toml`) or runtime overrides. - **Deploy**: Launch R2R using Docker, cloud platforms, or local installations. - **Implement**: Integrate R2R into applications using provided APIs and SDKs. - **Interact**: Users engage with the R2R application through interfaces like dashboards or APIs to perform RAG queries or search documents. ### User Interaction - **Users** interact with the R2R application, typically over an HTTP interface, to run RAG queries or search documents. - Access the **R2R Dashboard** for managing documents, collections, and performing searches. ### Hello R2R (Code Example) **Python Example** at `core/examples/hello_r2r.py`: ```python from r2r import R2RClient client = R2RClient("http://localhost:7272") # Create a test document with open("test.txt", "w") as file: file.write("John is a person that works at Google.") client.documents.create(file_path="test.txt") # Call RAG directly rag_response = client.retrieval.rag( query="Who is John", rag_generation_config={"model": "openai/gpt-4.1-mini", "temperature": 0.0}, ) results = rag_response["results"] print(f"Search Results:\n{results['search_results']}") print(f"Completion:\n{results['completion']}") ``` **Sample Output:** ```json { "results": { "search_results": { "chunk_search_results": [ { "chunk_id": "b9f40dbd-2c8e-5c0a-8454-027ac45cb0ed", "document_id": "7c319fbe-ca61-5770-bae2-c3d0eaa8f45c", "score": 0.6847735847465275, "text": "John is a person that works at Google.", "metadata": { "version": "v0", "chunk_order": 0, "document_type": "txt", "associated_query": "Who is John" } } ], "kg_search_results": [] }, "completion": { "id": "chatcmpl-AV1Sc9DORfHvq7yrmukxfJPDV5dCB", "choices": [ { "finish_reason": "stop", "index": 0, "message": { "content": "John is a person that works at Google [1].", "role": "assistant" } } ], "created": 1731957146, "model": "gpt-4.1-mini", "object": "chat.completion", "usage": { "completion_tokens": 11, "prompt_tokens": 145, "total_tokens": 156 } } } } ``` This snippet: 1. Creates a file with simple text. 2. Ingests it to R2R. 3. Runs a **Retrieval-Augmented Generation** query. 4. Prints the context matched (“search_results”) and the generated answer (“completion”). --- ## Configuration R2R is highly configurable, allowing you to tailor its behavior to your specific needs. Configuration can be done at the server-side using configuration files (`r2r.toml`) or at runtime via API calls. ### Configuration Overview R2R configurations are divided into two primary levels: 1. **Server-Side Configuration**: Managed through the `r2r.toml` file and environment variables. 2. **Runtime Overrides**: Passed directly in API calls to adjust settings dynamically. ### Server-Side Configuration (`r2r.toml`) The `r2r.toml` file allows you to define server-side settings that govern the behavior of R2R. Below are the main configuration sections: #### Example: `r2r.toml` ```toml [completion] provider = "litellm" concurrent_request_limit = 16 [completion.generation_config] model = "openai/gpt-4.1" temperature = 0.5 [ingestion] provider = "r2r" chunking_strategy = "recursive" chunk_size = 1024 chunk_overlap = 512 excluded_parsers = [] [database] provider = "postgres" user = "your_postgres_user" password = "your_postgres_password" host = "your_postgres_host" port = "your_postgres_port" db_name = "your_database_name" project_name = "your_project_name" [embedding] provider = "litellm" base_model = "openai/text-embedding-3-small" base_dimension = 512 batch_size = 512 rerank_model = "BAAI/bge-reranker-v2-m3" concurrent_request_limit = 256 [auth] provider = "r2r" require_authentication = true require_email_verification = false default_admin_email = "admin@example.com" default_admin_password = "change_me_immediately" access_token_lifetime_in_minutes = 60 refresh_token_lifetime_in_days = 7 secret_key = "your-secret-key" [ingestion.chunk_enrichment_settings] enable_chunk_enrichment = true strategies = ["semantic", "neighborhood"] forward_chunks = 3 backward_chunks = 3 semantic_neighbors = 10 semantic_similarity_threshold = 0.7 generation_config = { model = "openai/gpt-4.1-mini" } [agent] rag_agent_static_prompt = "rag_agent" tools = ["search_file_knowledge", "web_search"] [database.graph_creation_settings] entity_types = [] relation_types = [] max_knowledge_triples = 100 fragment_merge_count = 4 generation_config = { model = "openai/gpt-4.1-mini" } [database.graph_enrichment_settings] max_description_input_length = 65536 max_summary_input_length = 65536 generation_config = { model = "openai/gpt-4.1-mini" } leiden_params = {} [database.graph_settings] generation_config = { model = "openai/gpt-4.1-mini" } ``` ### Runtime Overrides Runtime overrides allow you to adjust configurations dynamically without modifying the `r2r.toml` file. This is useful for temporary changes or testing different settings on the fly. **Example: Customizing RAG Query at Runtime** ```python rag_response = client.retrieval.rag( query="Who is Jon Snow?", rag_generation_config={ "model": "anthropic/claude-3-haiku-20240307", "temperature": 0.7 }, search_settings={ "use_semantic_search": True, "limit": 20, "use_hybrid_search": True } ) ``` ### Postgres Configuration R2R uses Postgres for relational and vector data storage, leveraging the `pgvector` extension for vector indexing. #### Example Configuration ```toml [database] provider = "postgres" user = "your_postgres_user" password = "your_postgres_password" host = "your_postgres_host" port = "your_postgres_port" db_name = "your_database_name" project_name = "your_project_name" ``` **Key Features:** - **pgvector**: Enables efficient vector operations. - **Full-Text Indexing**: Utilizes Postgres’s `ts_rank` for full-text search. - **JSONB**: Stores flexible metadata. ### Embedding Configuration R2R uses **LiteLLM** to manage embedding providers, allowing flexibility in selecting different LLM providers. #### Example Configuration ```toml [embedding] provider = "litellm" base_model = "openai/text-embedding-3-small" base_dimension = 512 batch_size = 512 rerank_model = "BAAI/bge-reranker-v2-m3" concurrent_request_limit = 256 ``` **Environment Variables:** - `OPENAI_API_KEY` - `HUGGINGFACE_API_KEY` - `ANTHROPIC_API_KEY` - `COHERE_API_KEY` - `OLLAMA_API_KEY` - etc. **Supported Providers:** - OpenAI - Azure - Anthropic - Cohere - Ollama - HuggingFace - Bedrock - Vertex AI - Voyage AI ### Auth & Users Configuration R2R’s authentication system supports secure user registration, login, session management, and access control. #### Example Configuration ```toml [auth] provider = "r2r" require_authentication = true require_email_verification = false default_admin_email = "admin@example.com" default_admin_password = "change_me_immediately" access_token_lifetime_in_minutes = 60 refresh_token_lifetime_in_days = 7 secret_key = "your-secret-key" ``` **Key Features:** - **JWT-Based Authentication**: Utilizes access and refresh tokens. - **Email Verification**: Optional, recommended for production. - **Superuser Management**: Default admin creation and superuser capabilities. ### Data Ingestion Configuration Configure how R2R ingests documents, including parsing, chunking, and embedding strategies. #### Example Configuration ```toml [ingestion] provider = "r2r" chunking_strategy = "recursive" chunk_size = 1024 chunk_overlap = 512 excluded_parsers = [] [ingestion.chunk_enrichment_settings] enable_chunk_enrichment = true strategies = ["semantic", "neighborhood"] forward_chunks = 3 backward_chunks = 3 semantic_neighbors = 10 semantic_similarity_threshold = 0.7 generation_config = { model = "openai/gpt-4.1-mini" } ``` **Modes:** - `fast`: Speed-oriented ingestion. - `hi-res`: Comprehensive, high-quality ingestion. - `custom`: Fine-grained control with a full `ingestion_config` dictionary. ### Retrieval Configuration Focuses on search settings, combining vector and knowledge-graph search capabilities. #### Example Configuration ```json { "search_settings": { "use_semantic_search": true, "limit": 20, "use_hybrid_search": true, "graph_search_settings": { "use_graph_search": true, "kg_search_type": "local" } } } ``` ### RAG Configuration Customize RAG (Retrieval-Augmented Generation) settings, including the language model's behavior. #### Example Configuration ```python rag_generation_config = { "model": "anthropic/claude-3-haiku-20240307", "temperature": 0.7, "top_p": 0.95, "max_tokens_to_sample": 1500, "stream": True } ``` ### Graphs Configuration Defines settings related to knowledge graph creation and enrichment. #### Example Configuration ```toml [database.graph_creation_settings] entity_types = [] relation_types = [] max_knowledge_triples = 100 fragment_merge_count = 4 generation_config = { model = "openai/gpt-4.1-mini" } [database.graph_enrichment_settings] max_description_input_length = 65536 max_summary_input_length = 65536 generation_config = { model = "openai/gpt-4.1-mini" } leiden_params = {} [database.graph_settings] generation_config = { model = "openai/gpt-4.1-mini" } ``` ### Prompts Configuration Manages prompt templates used for various tasks within R2R. #### Example Configuration Prompts are stored in Postgres and can be managed via the SDK. **Example: Adding a Prompt** ```python response = client.prompts.add_prompt( name="my_new_prompt", template="Hello, {name}! Welcome to {service}.", input_types={"name": "str", "service": "str"} ) ``` --- ## Data Ingestion ### Introduction R2R provides a powerful and flexible ingestion pipeline to process and manage various types of documents. It supports a wide range of file formats—text, documents, PDFs, images, audio, and video—and transforms them into searchable, analyzable content. The ingestion process includes parsing, chunking, embedding, and optionally extracting entities and relationships for knowledge graph construction. This section will guide you through: - Ingesting files, raw text, or pre-processed chunks - Choosing an ingestion mode (`fast`, `hi-res`, or `custom`) - Updating and deleting documents and chunks For more on configuring ingestion, see the [Ingestion Configuration Overview](https://r2r-docs.sciphi.ai/documentation/configuration/ingestion) and [Parsing & Chunking](https://r2r-docs.sciphi.ai/documentation/configuration/ingestion/parsing_and_chunking). ### Ingestion Modes R2R offers three primary ingestion modes to tailor the process to your requirements: | Mode | Description | |---------|----------------------------------------------------------------------------------------------------------------------| | `fast` | Speed-oriented ingestion that prioritizes rapid processing with minimal enrichment. Ideal for quickly processing large volumes of documents. | | `hi-res`| Comprehensive, high-quality ingestion that may leverage multimodal foundation models for parsing complex documents and PDFs. Suitable for documents requiring detailed analysis. | | `custom`| Advanced mode offering fine-grained control. Users provide a full `ingestion_config` dict or object to specify parser options, chunking strategy, character limits, and more. | **Example Usage:** ```python file_path = 'path/to/file.txt' metadata = {'key1': 'value1'} # hi-res mode for thorough extraction ingest_response = client.documents.create( file_path=file_path, metadata=metadata, ingestion_mode="hi-res" ) # fast mode for quick processing ingest_response = client.documents.create( file_path=file_path, ingestion_mode="fast" ) # custom mode for full control ingest_response = client.documents.create( file_path=file_path, ingestion_mode="custom", ingestion_config={ "provider": "unstructured_local", "strategy": "auto", "chunking_strategy": "by_title", "new_after_n_chars": 256, "max_characters": 512, "combine_under_n_chars": 64, "overlap": 100, } ) ``` ### Ingesting Documents A `Document` represents ingested content in R2R. When you ingest a file, text, or chunks: 1. **Parsing**: Converts source files into text. 2. **Chunking**: Breaks text into manageable units. 3. **Embedding**: Generates embeddings for semantic search. 4. **Storing**: Persists chunks and embeddings for retrieval. 5. **Knowledge Graph Integration**: Optionally extracts entities and relationships. In a **full** R2R installation, ingestion is asynchronous. Monitor ingestion status and confirm when documents are ready: ```bash r2r documents list ``` **Example Response:** ```json { "id": "9fbe403b-c11c-5aae-8ade-ef22980c3ad1", "title": "file.txt", "user_id": "2acb499e-8428-543b-bd85-0d9098718220", "type": "txt", "created_at": "2024-09-05T18:20:47.921933Z", "updated_at": "2024-09-05T18:20:47.921938Z", "ingestion_status": "success", "restructuring_status": "pending", "version": "v0", "summary": "The document contains a ....", "collection_ids": [], "metadata": {"version": "v0"} } ``` An `ingestion_status` of `"success"` confirms the document is fully ingested. Also, check the R2R dashboard at [http://localhost:7273](http://localhost:7273/) for ingestion progress and status. For more details on creating documents, refer to the [Create Document API](https://r2r-docs.sciphi.ai/api-and-sdks/documents/create-document). ### Ingesting Pre-Processed Chunks If you have pre-processed chunks from your own pipeline, ingest them directly. Useful if content is already divided into logical segments. **Example:** ```python chunks = ["This is my first parsed chunk", "This is my second parsed chunk"] ingest_response = client.documents.create( chunks=chunks, ingestion_mode="fast" # use fast for quick chunk ingestion ) print(ingest_response) # {'results': [{'message': 'Document created and ingested successfully.', 'document_id': '7a0dad00-b041-544e-8028-bc9631a0a527'}]} ``` For more on ingesting chunks, see the [Create Chunks API](https://r2r-docs.sciphi.ai/api-and-sdks/chunks/create-chunks). ### Deleting Documents and Chunks To remove documents or chunks, use their respective `delete` methods. **Delete a Document:** ```bash curl -X DELETE http://localhost:7272/v3/documents/9fbe403b-c11c-5aae-8ade-ef22980c3ad1 \ -H "Content-Type: application/json" ``` **Sample Output:** ```json {"results": {"success": true}} ``` **Key Features of Deletion:** 1. **Deletion by Document ID**: Remove specific documents. 2. **Cascading Deletion**: Deletes associated chunks and metadata. 3. **Deletion by Filter**: Delete documents based on criteria like text match or user ID using `documents/by-filter`. This mechanism ensures precise control over document management within R2R. For advanced document management and user authentication details, refer to the [User Auth Cookbook](https://r2r-docs.sciphi.ai/cookbooks/user-auth). ### Additional Configuration & Concepts - **Light vs. Full Deployments**: - **Light**: Uses R2R’s built-in parser and supports synchronous ingestion. - **Full**: Orchestrates ingestion tasks asynchronously and integrates with complex providers like `unstructured_local`. - **Provider Configuration**: - Settings in `r2r.toml` or at runtime (`ingestion_config`) adjust parsing and chunking strategies. - `fast` and `hi-res` modes influenced by strategies like `"auto"` or `"hi_res"`. - `custom` mode allows overriding chunk size, overlap, excluded parsers, and more at runtime. For detailed configuration options, see: - [Data Ingestion Configuration](https://r2r-docs.sciphi.ai/documentation/configuration/ingestion) - [Parsing & Chunking Configuration](https://r2r-docs.sciphi.ai/documentation/configuration/ingestion/parsing_and_chunking) ### Conclusion R2R’s ingestion pipeline is flexible and efficient, allowing you to tailor ingestion to your needs: - Use `fast` for quick processing. - Use `hi-res` for high-quality, multimodal analysis. - Use `custom` for advanced, granular control. Easily ingest documents or pre-processed chunks, update their content, and delete them when no longer needed. Combined with powerful retrieval and knowledge graph capabilities, R2R enables seamless integration of advanced document management into your applications. --- ## Contextual Enrichment Enhance your RAG system chunks with rich contextual information to address the challenge of context loss in individual chunks. ### The Challenge of Context Loss During ingestion, large documents are broken down into smaller chunks for efficient processing. However, isolated chunks may lack broader context, leading to incomplete or unclear responses. **Example:** Using Lyft’s 2021 annual report: - **Original Chunk:** ``` storing unrented and returned vehicles. These impacts to the demand for and operations of the different rental programs have and may continue to adversely affect our business, financial condition and results of operation. ``` - **Questions Raised:** - What specific impacts are being discussed? - Which rental programs are affected? - What’s the broader context of these business challenges? ### Introducing Contextual Enrichment Contextual enrichment enhances chunks with relevant information from surrounding or semantically related content, giving each chunk a “memory” of related information. ### Enabling Enrichment Configure your `r2r.toml` file with the following settings: ```toml [ingestion.chunk_enrichment_settings] enable_chunk_enrichment = true # disabled by default strategies = ["semantic", "neighborhood"] forward_chunks = 3 # Look ahead 3 chunks backward_chunks = 3 # Look behind 3 chunks semantic_neighbors = 10 # Find 10 semantically similar chunks semantic_similarity_threshold = 0.7 # Minimum similarity score generation_config = { model = "openai/gpt-4.1-mini" } ``` ### Enrichment Strategies Explained R2R implements two strategies for chunk enrichment: #### 1. Neighborhood Strategy - **Forward Looking**: Captures upcoming context (default: 3 chunks). - **Backward Looking**: Incorporates previous context (default: 3 chunks). - **Use Case**: Effective for narrative documents with linear context flow. #### 2. Semantic Strategy - **Vector Similarity**: Identifies chunks with similar meanings regardless of location. - **Configurable Neighbors**: Customizable number of similar chunks. - **Similarity Threshold**: Ensures relevance by setting minimum similarity scores. - **Use Case**: Ideal for documents with recurring themes across sections. ### The Enrichment Process R2R uses a prompt to guide the Language Model (LLM) during enrichment: **Task:** Enrich and refine the given chunk of text using information from the provided context chunks. The goal is to make the chunk more precise and self-contained. **Context Chunks:** ``` {context_chunks} ``` **Chunk to Enrich:** ``` {chunk} ``` **Instructions:** 1. Rewrite the chunk in third person. 2. Replace all common nouns with appropriate proper nouns. 3. Use information from the context chunks to enhance clarity. 4. Ensure the enriched chunk remains independent and self-contained. 5. Maintain original scope without bleeding information. 6. Focus on precision and informativeness. 7. Preserve original meaning while improving clarity. 8. Output only the enriched chunk. **Enriched Chunk:** ``` [Enriched Chunk Output] ``` ### Implementation and Results To process documents with enrichment: ```bash r2r documents create --file_path path/to/lyft_2021.pdf ``` #### Viewing Enriched Results Access enriched chunks through the API: ```bash curl -X GET http://localhost:7272/v3/document/{document_id}/chunks ``` **Before Enrichment:** ``` storing unrented and returned vehicles. These impacts to the demand for and operations of the different rental programs have and may continue to adversely affect our business, financial condition and results of operation. ``` **After Enrichment:** ``` The impacts of the COVID-19 pandemic on the demand for and operations of the various vehicle rental programs, including Lyft Rentals and the Express Drive program, have resulted in challenges regarding the storage of unrented and returned vehicles. These adverse conditions are anticipated to continue affecting Lyft's overall business performance, financial condition, and operational results. ``` **Enhancements in Enriched Chunk:** - Specifies the cause (COVID-19 pandemic). - Names specific programs (Lyft Rentals, Express Drive). - Provides clearer context about the business impact. - Maintains professional, third-person tone. ### Metadata and Storage R2R maintains both enriched and original versions: ```json { "results": [ { "text": "enriched_version", "metadata": { "original_text": "original_version", "chunk_enrichment_status": "success" // ... additional metadata ... } } ] } ``` This dual storage ensures transparency and allows for version comparison when needed. ### Best Practices 1. **Tune Your Parameters**: Adjust `forward_chunks`, `backward_chunks`, and `semantic_neighbors` based on document structure. 2. **Monitor Enrichment Quality**: Regularly review enriched chunks to ensure accuracy. 3. **Consider Document Type**: Different documents may benefit from different enrichment strategies. 4. **Balance Context Size**: More context isn’t always better; find the optimal size for your use case. --- ## AI Powered Search R2R supports advanced search capabilities, including vector search, hybrid search (keyword + vector), and knowledge graph-enhanced search. This section covers the understanding of search modes, configuration, and best practices. ### Introduction R2R’s hybrid search blends keyword-based full-text search with semantic vector search, delivering results that are both contextually relevant and precise. This unified approach excels at handling complex queries where both exact terms and overall meaning matter. ### Understanding Search Modes R2R supports multiple search modes to simplify or customize your search configuration: | Mode | Description | |-----------|----------------------------------------------------------------------------------------------------------------------| | `basic` | Primarily semantic search. Suitable for straightforward scenarios where semantic understanding is key. | | `advanced`| Combines semantic and full-text search by default, enabling hybrid search with well-tuned default parameters. | | `custom` | Allows full control over search settings, including toggling semantic and full-text search independently. | - **`advanced` Mode**: Automatically configures hybrid search with balanced parameters. - **`custom` Mode**: Manually set `use_hybrid_search=True` or enable both `use_semantic_search` and `use_fulltext_search` for a hybrid setup. ### How R2R Hybrid Search Works 1. **Full-Text Search**: - Utilizes Postgres’s `ts_rank_cd` and `websearch_to_tsquery` for exact term matches. 2. **Semantic Search**: - Employs vector embeddings to locate contextually related documents, even without exact keyword matches. 3. **Reciprocal Rank Fusion (RRF)**: - Merges results from both full-text and semantic searches using a formula to ensure balanced ranking. 4. **Result Ranking**: - Orders results based on the combined RRF score, providing balanced and meaningful search outcomes. ### Vector Search Vector search leverages semantic embeddings to find documents that are contextually similar to the query, even if they don't contain the exact keywords. **Example:** ```bash curl -X POST http://localhost:7272/v3/retrieval/search \ -H "Content-Type: application/json" \ -d '{ "query": "What was Uber'\''s profit in 2020?", "search_settings": { "use_semantic_search": true, "search_settings": { "chunk_settings": { "index_measure": "l2_distance", "limit": 10 } } } }' ``` **Sample Output:** Includes chunk-based results with text, metadata, etc. ### Hybrid Search Hybrid search combines keyword-based full-text search with semantic vector search to deliver more relevant results. **Example:** ```bash curl -X POST http://localhost:7272/v3/retrieval/search \ -H "Content-Type: application/json" \ -d '{ "query": "What was Uber'\''s profit in 2020?", "search_settings": { "use_hybrid_search": true, "hybrid_settings": { "full_text_weight": 1.0, "semantic_weight": 5.0, "full_text_limit": 200, "rrf_k": 50 }, "filters": { "title": { "$in": ["lyft_2021.pdf", "uber_2021.pdf"] } }, "limit": 10, "chunk_settings": { "index_measure": "l2_distance", "probes": 25, "ef_search": 100 } } }' ``` ### Knowledge Graph Search Knowledge graph search enhances retrieval by leveraging relationships and entities extracted from documents. **Example:** ```bash curl -X POST http://localhost:7272/v3/retrieval/search \ -H "Content-Type: application/json" \ -d '{ "query": "Who was Aristotle?", "graph_search_settings": { "use_graph_search": true, "kg_search_type": "local" } }' ``` ### Reciprocal Rank Fusion (RRF) RRF is a technique used to merge results from different search strategies, ensuring balanced and relevant ranking. ### Result Ranking Results are ranked based on the combined RRF score, providing a balanced mix of exact term matches and semantic relevance. ### Configuration **Choosing a Search Mode:** | Mode | Description | Example Configuration | |-----------|-----------------------------------------------------------|-----------------------------------------------------------------------| | `basic` | Semantic-only search | `search_mode = "basic"` | | `advanced`| Hybrid search with well-tuned defaults | `search_mode = "advanced"` | | `custom` | Manually configure hybrid search settings | ```python
search_mode = "custom"
search_settings = {
"use_semantic_search": True,
"use_fulltext_search": True,
"hybrid_settings": {
"full_text_weight": 1.0,
"semantic_weight": 5.0,
"full_text_limit": 200,
"rrf_k": 50
}
}``` | For detailed runtime configuration and combining `search_mode` with custom `search_settings`, refer to the [Search API Documentation](https://r2r-docs.sciphi.ai/api-and-sdks/retrieval/search-app). ### Best Practices 1. **Optimize Database and Embeddings**: - Ensure Postgres indexing and vector store configurations are optimized for performance. 2. **Adjust Weights and Limits**: - Tweak `full_text_weight`, `semantic_weight`, and `rrf_k` values in `custom` mode. 3. **Regular Updates**: - Keep embeddings and indexes up-to-date to maintain search quality. 4. **Choose Appropriate Embeddings**: - Select an embedding model that fits your content domain for the best semantic results. ### Conclusion R2R’s hybrid search delivers robust, context-aware retrieval by merging semantic and keyword-driven approaches. Whether you choose `basic` mode for simplicity, `advanced` mode for out-of-the-box hybrid search, or `custom` mode for granular control, R2R ensures you can tailor the search experience to your unique needs. --- ## Retrieval-Augmented Generation (RAG) R2R couples its powerful retrieval capabilities with large language models (LLMs) to provide comprehensive Q&A and content generation based on ingested documents. ### Basic RAG **Example:** ```bash curl -X POST http://localhost:7272/v3/retrieval/rag \ -H "Content-Type: application/json" \ -d '{ "query": "What was Uber'\''s profit in 2020?" }' ``` **Sample Output:** ```json { "results": [ "ChatCompletion(...)" ] } ``` ### RAG with Hybrid Search Combine hybrid search logic with RAG for enhanced results. **Example:** ```bash curl -X POST http://localhost:7272/v3/retrieval/rag \ -H "Content-Type: application/json" \ -d '{ "query": "Who is Jon Snow?", "search_settings": { "use_hybrid_search": true, "limit": 10 } }' ``` ### Streaming RAG Stream RAG responses in real-time, providing partial results as they are generated. **Example:** ```bash r2r retrieval rag --query="who was aristotle" --use-hybrid-search=True --stream ``` It streams real-time tokens. ### Customizing RAG You can control various aspects of RAG, including search settings, generation config, and LLM providers. **Example:** ```bash curl -X POST http://localhost:7272/v3/retrieval/rag \ -H "Content-Type: application/json" \ -d '{ "query": "Who is Jon Snow?", "rag_generation_config": { "model": "claude-3-haiku-20240307", "temperature": 0.7 } }' ``` ### Advanced RAG Techniques R2R supports advanced RAG techniques, currently in beta, including HyDE and RAG-Fusion. #### HyDE (Hypothetical Document Embeddings) HyDE enhances retrieval by generating and embedding hypothetical documents based on the query. **Workflow:** 1. **Query Expansion**: Generates hypothetical answers or documents using an LLM. 2. **Enhanced Embedding**: Embeds these hypothetical documents to create a richer semantic search space. 3. **Similarity Search**: Uses the embeddings to find the most relevant actual documents in the database. 4. **Informed Generation**: Combines retrieved documents and the original query to generate the final response. **Python Example:** ```python from r2r import R2RClient client = R2RClient() hyde_response = client.retrieval.rag( "What are the main themes in Shakespeare's plays?", search_settings={ "search_strategy": "hyde", "limit": 10 } ) print('hyde_response = ', hyde_response) ``` **Sample Output:** ```json { "results": { "completion": "...", "search_results": { "chunk_search_results": [ { "score": 0.7715058326721191, "text": "## Paragraph from the Chapter...", "metadata": { "associated_query": "The fundamental theorem of calculus..." } } ] } } } ``` #### RAG-Fusion RAG-Fusion improves retrieval quality by combining results from multiple search iterations. **Workflow:** 1. **Query Expansion**: Generates multiple related queries. 2. **Multiple Retrievals**: Each query retrieves relevant documents. 3. **Reciprocal Rank Fusion (RRF)**: Re-ranks documents using RRF. 4. **Enhanced RAG**: Uses re-ranked documents to generate the final response. **Python Example:** ```python from r2r import R2RClient client = R2RClient() rag_fusion_response = client.retrieval.rag( "Explain the theory of relativity", search_settings={ "search_strategy": "rag_fusion", "limit": 20 } ) print('rag_fusion_response = ', rag_fusion_response) ``` **Sample Output:** ```json { "results": { "completion": "...", "search_results": { "chunk_search_results": [ { "score": 0.04767399003253049, "text": "18. The theory of relativity, proposed by Albert Einstein in 1905...", "metadata": { "associated_queries": ["What is the theory of relativity?", ...] } } ] } } } ``` ### Combining with Other Settings You can combine advanced RAG techniques with other search and RAG settings for enhanced performance. **Example:** ```python custom_rag_response = client.retrieval.rag( "Describe the impact of climate change on biodiversity", search_settings={ "search_strategy": "hyde", "limit": 15, "use_hybrid_search": True }, rag_generation_config={ "model": "anthropic/claude-3-opus-20240229", "temperature": 0.7 } ) ``` ### Customization and Server-Side Defaults While R2R allows runtime configuration of advanced techniques, server-side defaults can also be modified for consistent behavior. This includes updating prompts used for techniques like HyDE and RAG-Fusion. - **General Configuration**: Refer to the [R2R Configuration Documentation](https://r2r-docs.sciphi.ai/documentation/configuration/overview). - **Customizing Prompts**: Learn about customizing prompts [here](https://r2r-docs.sciphi.ai/documentation/configuration/retrieval/prompts). **Example:** ```toml [rag_generation_config] model = "anthropic/claude-3-opus-20240229" temperature = 0.7 ``` ### Conclusion By leveraging advanced RAG techniques and customizing their underlying prompts, you can significantly enhance the quality and relevance of your retrieval and generation processes. Experiment with different strategies, settings, and prompt variations to find the optimal configuration for your specific use case. R2R's flexibility allows iterative improvement and adaptation to changing requirements. --- ## Knowledge Graphs in R2R Knowledge graphs enhance search accuracy and context understanding by extracting and connecting information from your documents. R2R uses a two-level architecture: 1. **Document Level**: Entities and relationships are first extracted and stored with their source documents. 2. **Collection Level**: Collections act as soft containers that include documents and maintain corresponding graphs. ### Overview R2R supports robust knowledge graph functionality to enhance document understanding and retrieval. By extracting entities and relationships from documents and organizing them into collections, R2R enables advanced graph-based analysis and search capabilities. **Note**: Refer to the [Knowledge Graph Cookbook](https://r2r-docs.sciphi.ai/cookbooks/knowledge-graphs) and [GraphRAG Cookbook](https://r2r-docs.sciphi.ai/cookbooks/graphrag) for detailed guides. ### System Architecture ``` Collection (Soft Container) | Documents |--> Extracted Entities & Relationships Knowledge Graph | Permissions | User ``` **Collections Provide:** - Flexible document organization (documents can belong to multiple collections) - Access control and sharing - Graph synchronization and updates ### Getting Started #### Document-Level Extraction Extract entities and relationships from documents. **Python Example:** ```python from r2r import R2RClient client = R2RClient("http://localhost:7272") # Extract entities and relationships document_id = "your-document-id" extract_response = client.documents.extract(document_id) # View extracted knowledge entities = client.documents.list_entities(document_id) relationships = client.documents.list_relationships(document_id) ``` #### Creating Collection Graphs Each collection maintains its own graph. **Python Example:** ```python # Create collection collection = client.collections.create( "Research Papers", "ML research papers with knowledge graph analysis" ) collection_id = collection["results"]["id"] # Add documents to collection client.collections.add_document(collection_id, document_id) # Generate description for the collection client.collections.update( collection_id, generate_description=True ) # Pull document knowledge into collection graph client.graphs.pull(collection_id) ``` #### Managing Collection Graphs **Python Example:** ```python # List entities in collection graph entities = client.graphs.list_entities(collection_id) # List relationships in collection graph relationships = client.graphs.list_relationships(collection_id) ``` **Example Output:** - **Entity:** ```json { "name": "DEEP_LEARNING", "description": "A subset of machine learning using neural networks", "category": "CONCEPT", "id": "ce46e955-ed77-4c17-8169-e878baf3fbb9" } ``` - **Relationship:** ```json { "subject": "DEEP_LEARNING", "predicate": "IS_SUBSET_OF", "object": "MACHINE_LEARNING", "description": "Deep learning is a specialized branch of machine learning" } ``` ### Graph-Collection Relationship - Each collection has an associated graph. - The `pull` operation syncs the graph with the collection. - Allows experimental modifications without affecting the base data. ### Knowledge Graph Workflow 1. **Extract Document Knowledge**: ```bash curl -X POST http://localhost:7272/v3/documents/${document_id}/extract ``` 2. **Initialize and Populate Graph**: ```bash curl -X POST http://localhost:7272/v3/graphs/${collection_id}/pull ``` 3. **View Entities and Relationships**: ```bash curl -X GET http://localhost:7272/v3/graphs/${collection_id}/entities curl -X GET http://localhost:7272/v3/graphs/${collection_id}/relationships ``` 4. **Build Graph Communities**: ```bash curl -X POST http://localhost:7272/v3/graphs/${collection_id}/communities/build curl -X GET http://localhost:7272/v3/graphs/${collection_id}/communities ``` 5. **KG-Enhanced Search**: ```bash curl -X POST http://localhost:7272/v3/retrieval/search \ -H "Content-Type: application/json" \ -d '{ "query": "who was aristotle?", "graph_search_settings": { "use_graph_search": true, "kg_search_type": "local" } }' ``` 6. **Reset Graph**: ```bash curl -X POST http://localhost:7272/v3/graphs/${collection_id}/reset ``` ### Graph Synchronization #### Document Updates When documents change: ```python # Update document client.documents.update(document_id, new_content) # Re-extract knowledge client.documents.extract(document_id) # Update collection graphs client.graphs.pull(collection_id) ``` #### Cross-Collection Updates Documents can belong to multiple collections: ```python # Add document to multiple collections client.collections.add_document(document_id, collection_id_1) client.collections.add_document(document_id, collection_id_2) # Update all relevant graphs client.graphs.pull(collection_id_1) client.graphs.pull(collection_id_2) ``` ### Access Control Manage access to graphs through collection permissions. **Python Example:** ```python # Give user access to collection and its graph client.collections.add_user(user_id, collection_id) # Remove access client.collections.remove_user(user_id, collection_id) # List users with access users = client.collections.list_users(collection_id) ``` ### Using Knowledge Graphs #### Search Integration Graphs automatically enhance search for collection members. **Curl Example:** ```bash curl -X POST http://localhost:7272/v3/retrieval/search \ -H "Content-Type: application/json" \ -d '{ "query": "What is deep learning?", "graph_search_settings": { "use_graph_search": true, "kg_search_type": "local" } }' ``` #### RAG Integration Knowledge graphs enhance RAG responses. **Python Example:** ```python response = client.retrieval.rag( "Explain deep learning's relationship to ML", graph_search_settings={ "enabled": True } ) ``` ### Best Practices #### Document Management - Extract knowledge after document updates. - Monitor extraction quality at the document level. - Extractions stay with source documents. - Consider document size and complexity when extracting. #### Collection Management - Keep collections focused on related documents. - Use meaningful collection names and descriptions. - Documents can belong to multiple collections. - Pull changes when document extractions update. #### Performance Optimization - Start with small document sets to test extraction. - Use collection-level operations for bulk processing. - Monitor graph size and complexity. - Consider using [orchestration](https://r2r-docs.sciphi.ai/cookbooks/orchestration) for large collections. #### Access Control - Plan collection structure around sharing needs. - Review access permissions regularly. - Document collection purposes and access patterns. - Use collection metadata to track graph usage. ### Troubleshooting **Common Issues and Solutions:** 1. **Missing Extractions**: - Verify document extraction completed successfully. - Check document format and content. - Ensure collection graph was pulled after extraction. 2. **Graph Sync Issues**: - Confirm all documents are properly extracted. - Check collection membership. - Try resetting and re-pulling collection graph. 3. **Performance Problems**: - Monitor collection size. - Check extraction batch sizes. - Consider splitting large collections. - Use pagination for large result sets. ### Conclusion R2R’s knowledge graph capabilities enhance document understanding and improve search and RAG operations by providing structured and interconnected information from your documents. ### Next Steps -

This approach provides richer context and more comprehensive answers by understanding how information is clustered and connected across your documents. ### Overview GraphRAG enhances RAG by integrating community detection and summarization within knowledge graphs, enabling more contextual and clustered information retrieval. #### Architecture ``` User Query | QueryTransformPipe | MultiSearchPipe | VectorSearchPipe | RAG-Fusion Process | Reciprocal Rank Fusion | RAG Generation | Knowledge Graph DB ``` ### Understanding Communities **Communities** are automatically detected clusters of related information in your knowledge graph, providing: 1. **Higher-Level Understanding**: Grasp document themes. 2. **Summarized Context**: Concise summaries for related concepts. 3. **Improved Retrieval**: Topic-based organization enhances search relevance. **Example Communities:** | Domain | Community Examples | |------------------|--------------------------------------------------------| | Scientific Papers| Research methods, theories, research teams | | News Articles | World events, industry sectors, key figures | | Technical Docs | System components, APIs, user workflows | | Legal Documents | Case types, jurisdictions, legal principles | ### Implementation Guide #### Prerequisites Ensure you have: - Documents ingested into a collection. - Entities and relationships extracted. - Graph synchronized. **Python Example:** ```python from r2r import R2RClient client = R2RClient("http://localhost:7272") # Setup collection and extract knowledge collection_id = "your-collection-id" client.collections.extract(collection_id) client.graphs.pull(collection_id) ``` #### Building Communities **Python Example:** ```python # Generate a description for the collection client.collections.update( collection_id, generate_description=True ) # Build communities for your collection's graph build_response = client.graphs.build(collection_id) ``` **Build Process Includes:** 1. Analyzes graph connectivity. 2. Identifies dense subgraphs. 3. Generates community summaries. 4. Creates findings and insights. #### Using GraphRAG Once communities are built, they integrate into search and RAG. **Python Example:** ```python # Search across all levels search_response = client.retrieval.search( "What are the key theories?", search_settings={ "graph_settings": { "enabled": True, } } ) # RAG with community context rag_response = client.retrieval.rag( "Explain the relationships between theories", graph_search_settings={ "enabled": True } ) ``` ### Understanding Results GraphRAG returns three types of results: #### 1. Document Chunks ```json { "chunk_id": "70c96e8f-e5d3-5912-b79b-13c5793f17b5", "text": "Example document text...", "score": 0.78, "metadata": { "document_type": "txt", "associated_query": "query text" } } ``` #### 2. Graph Elements ```json { "content": { "name": "CONCEPT_NAME", "description": "Entity description..." }, "result_type": "entity", "score": 0.74 } ``` #### 3. Communities ```json { "content": { "name": "Community Name", "summary": "High-level community description...", "findings": [ "Key insight 1 with supporting evidence...", "Key insight 2 with supporting evidence..." ], "rating": 9.0, "rating_explanation": "Explanation of importance..." }, "result_type": "community", "score": 0.57 } ``` ### Scaling GraphRAG #### Using Orchestration For large collections, utilize R2R’s orchestration capabilities via Hatchet UI. **Access Hatchet UI:** - **URL**: [http://localhost:7274](http://localhost:7274) - **Login Credentials**: - **Email**: admin@example.com - **Password**: Admin123!! **Features:** - Monitor document extraction progress. - Track community detection status. - Handle errors and workflow retries. **Example Diagram:** ![Monitoring GraphRAG workflows in Hatchet](https://files.buildwithfern.com/https://sciphi.docs.buildwithfern.com/2024-12-13T18:29:49.890Z/images/hatchet_workflow.png) ### Best Practices 1. **Development**: - Start with small document sets. - Test with single documents first. - Scale gradually to larger collections. 2. **Performance**: - Monitor community size and complexity. - Use pagination for large result sets. - Consider breaking very large collections. 3. **Quality**: - Review community summaries. - Validate findings accuracy. - Monitor retrieval relevance. ### Troubleshooting **Common Issues and Solutions:** 1. **Poor Community Quality**: - Check entity extraction quality. - Review relationship connections. - Adjust collection scope. 2. **Performance Issues**: - Monitor graph size. - Check community complexity. - Use orchestration for large graphs. 3. **Integration Problems**: - Verify extraction completion. - Check collection synchronization. - Review API configurations. ### Next Steps - Explore [hybrid search](https://r2r-docs.sciphi.ai/cookbooks/hybrid-search) integration. - Learn about [collection management](https://r2r-docs.sciphi.ai/cookbooks/collections). - Discover more about [observability](https://r2r-docs.sciphi.ai/cookbooks/observability). ### Conclusion GraphRAG enhances R2R’s RAG capabilities by integrating community detection and summarization within knowledge graphs. This results in richer, more contextualized responses, improving the overall quality of information retrieval and generation. --- ## Agent R2R’s agentic capabilities allow for intelligent systems that formulate their own questions, search for information, and provide informed responses based on retrieved context. Agents can be customized on the fly to suit various tasks. **Note**: Agents in R2R are in beta. Feedback is encouraged at [founders@sciphi.ai](mailto:founders@sciphi.ai). ### Understanding R2R’s RAG Agent R2R’s RAG agent combines large language models with search capabilities over ingested documents to provide powerful, context-aware responses. When initializing an R2R application, it automatically creates a RAG assistant ready for use. **Planned Extensions:** - Multiple tool support (e.g., code interpreter, file search) - Persistent conversation threads - Complete end-to-end observability of agent interactions - Local RAG capabilities for offline AI agents ### Configuration The RAG agent is configured through the `r2r.toml` file. By default, it uses local search. **Default Configuration:** ```toml [agent] rag_agent_static_prompt = "rag_agent" tools = ["search_file_knowledge"] ``` **Enable Web Search:** ```toml [agent] rag_agent_static_prompt = "rag_agent" tools = ["search_file_knowledge", "web_search"] ``` ### Using the RAG Agent Access the agent through the R2R API via the `agent` endpoint. **Python Example:** ```python from r2r import R2RClient # Initialize the client client = R2RClient("http://localhost:7272") # Make a simple query first_reply = client.retrieval.agent( message={"role": "user", "content": "Who was Aristotle?"}, search_settings={"limit": 5, "filters": {}}, ) # Save the conversation ID for continued interaction conversation_id = first_reply["results"]["conversation_id"] # Make a follow-up query using the conversation context second_reply = client.retrieval.agent( message={"role": "user", "content": "What were his contributions to philosophy?"}, search_settings={"limit": 5, "filters": {}}, conversation_id=conversation_id, ) ``` **Streaming Responses:** ```python streaming_response = client.agent( message={"role": "user", "content": "Who was Aristotle?"}, search_settings={"limit": 5, "filters": {}}, rag_generation_config={"max_tokens": 300, "stream": True}, conversation_id=conversation_id, ) print("Streaming RAG Assistant Response:") for chunk in streaming_response: print(chunk, end="", flush=True) ``` ### Context-Aware Responses The agent maintains conversation context, enabling it to handle follow-up questions intelligently based on conversation history. ### Working with Files The Conversation API allows the agent to be aware of specific files within a conversation. **Python Example:** ```python # Create a new conversation conversation = client.conversations.create("results") # Inform the agent about available files client.conversations.add_message( conversation_id=conversation["id"], role="system", content="You have access to the following file: {document_info['title']}" ) # Query with file context response = client.retrieval.agent( message={ "role": "user", "content": "Summarize the main points of the document" }, search_settings={"limit": 5, "filters": {}}, conversation_id=conversation["id"] ) ``` ### Advanced Features #### Combined Search Capabilities When both local and web search are enabled, the agent can: - Search through your local document store. - Perform web searches for additional context. - Maintain conversation context. - Synthesize information from multiple sources. **Example:** ```python response = client.retrieval.agent( message={ "role": "user", "content": "Compare historical and modern interpretations" }, search_settings={ "limit": 5, "filters": {}, "use_web_search": True # requires `Serper` API key }, conversation_id=conversation_id ) ``` #### Custom Search Settings Customize search behavior using the `search_settings` parameter. **Example:** ```python response = client.retrieval.agent( message={"role": "user", "content": "Query"}, search_settings={ "limit": 5, # Number of results to return "filters": { "date": "2023", # Example filter "category": "technology" } } ) ``` ### Best Practices 1. **Conversation Management**: - Maintain conversation IDs for related queries. - Use the system role to provide context about available files. - Clear conversation context when starting new topics. 2. **Search Optimization**: - Adjust the `limit` parameter based on needed context. - Use filters to narrow search scope. - Consider enabling web search for broader context. 3. **Response Handling**: - Use streaming for long responses. - Process response chunks appropriately in streaming mode. - Check for error messages in responses. ### Error Handling The agent may return error messages in the response. Always check for errors. **Python Example:** ```python from r2r import R2RException try: await client.retrieval.agent(...) except R2RException as e: if e.status_code == 401: print("Invalid credentials") elif e.status_code == 400: print("Email not verified") ``` ### Limitations - **Beta Feature**: The agent is currently in beta. - **Web Search Requirements**: Requires additional configuration. - **Streaming Response Structure**: May differ from non-streaming responses. - **Offline Mode Limitations**: Some features may not be available offline. ### Future Developments R2R plans to enhance the agent system with: - Enhanced tool integration. - Improved conversation management. - Better search capabilities. - More customization options. Stay updated with the latest developments by checking the R2R documentation regularly. ### Conclusion R2R’s agent system provides powerful, context-aware interactions by combining LLMs with advanced search capabilities. By leveraging these features, you can create intelligent assistants that offer comprehensive and accurate responses based on your document corpus. --- ## Orchestration Orchestration in R2R is managed using [Hatchet](https://docs.hatchet.run/home), a distributed, fault-tolerant task queue that handles complex workflows such as ingestion and knowledge graph construction. ### Key Concepts | Concept | Description | |------------------|-----------------------------------------------------------------------------| | **Workflows** | Sets of functions executed in response to external triggers. | | **Workers** | Long-running processes that execute workflow functions. | | **Managed Queue**| Low-latency queue for handling real-time tasks. | ### Orchestration in R2R #### Benefits of Orchestration 1. **Scalability**: Efficiently handles large-scale tasks. 2. **Fault Tolerance**: Built-in retry mechanisms and error handling. 3. **Flexibility**: Easy to add or modify workflows as R2R’s capabilities expand. #### Workflows in R2R 1. **IngestFilesWorkflow**: Handles file ingestion, parsing, chunking, and embedding. 2. **UpdateFilesWorkflow**: Manages updating existing files. 3. **KgExtractAndStoreWorkflow**: Extracts and stores knowledge graph information. 4. **CreateGraphWorkflow**: Orchestrates knowledge graph creation. 5. **EnrichGraphWorkflow**: Handles graph enrichment processes like node creation and clustering. ### Orchestration GUI Access the Hatchet front-end application at [http://localhost:7274](http://localhost:7274). #### Login Use the following credentials to log in: - **Email**: admin@example.com - **Password**: Admin123!! ![Logging into Hatchet](https://files.buildwithfern.com/https://sciphi.docs.buildwithfern.com/2024-12-13T18:29:49.890Z/images/hatchet_login.png) #### Running Tasks After initiating tasks like `r2r documents create-samples`, view running workflows: ![Running Workflows](https://files.buildwithfern.com/https://sciphi.docs.buildwithfern.com/2024-12-13T18:29:49.890Z/images/hatchet_running.png) #### Inspecting a Workflow Inspect and manage individual workflows, including retrying failed jobs: ![Inspecting a Workflow](https://files.buildwithfern.com/https://sciphi.docs.buildwithfern.com/2024-12-13T18:29:49.890Z/images/hatchet_workflow.png) #### Long Running Tasks Hatchet supports long-running tasks, essential for processes like graph construction. ![Long Running Tasks](https://files.buildwithfern.com/https://sciphi.docs.buildwithfern.com/2024-12-13T18:29:49.890Z/images/hatchet_long_running.png) ### Coming Soon Details about upcoming orchestration features will be available soon. ### Best Practices 1. **Development**: - Start with small document sets. - Test with single documents first. - Scale gradually to larger collections. 2. **Performance**: - Monitor community size and complexity. - Use pagination for large result sets. - Consider breaking very large collections. 3. **Quality**: - Review community summaries. - Validate findings accuracy. - Monitor retrieval relevance. ### Troubleshooting **Common Issues and Solutions:** 1. **Unable to Create/Modify Collections**: - Ensure the user has superuser privileges. 2. **User Not Seeing Collection Content**: - Verify that the user is correctly added to the collection. - Ensure documents are properly assigned. 3. **Performance Issues with Large Collections**: - Use pagination when retrieving users or documents. - Consider splitting large collections. ### Conclusion Orchestration via Hatchet enables R2R to handle complex and large-scale workflows efficiently. By leveraging workflows and monitoring tools, you can ensure smooth and scalable operations within your R2R deployment. --- ## Maintenance & Scaling Effective maintenance and scaling are crucial for ensuring R2R operates optimally, especially as data volumes grow. ### Vector Indices #### Do You Need Vector Indices? Vector indices are **not necessary for all deployments**, particularly in multi-user applications where queries are typically filtered by `user_id`, reducing the number of vectors searched. **Consider implementing vector indices when:** - Users search across hundreds of thousands of documents. - Query latency becomes a bottleneck even with user-specific filtering. - Supporting cross-user search functionality at scale. For development or smaller deployments, the overhead of maintaining vector indices often outweighs their benefits. #### Vector Index Management R2R supports multiple indexing methods, with HNSW (Hierarchical Navigable Small World) being recommended for most use cases. **Python Example: Creating and Deleting a Vector Index** ```python from r2r import R2RClient client = R2RClient() # Create vector index create_response = client.indices.create( { "table_name": "vectors", "index_method": "hnsw", "index_measure": "cosine_distance", "index_arguments": { "m": 16, # Number of connections per element "ef_construction": 64 # Size of dynamic candidate list }, } ) # List existing indices indices = client.indices.list() # Delete an index delete_response = client.indices.delete( index_name="ix_vector_cosine_ops_hnsw__20241021211541", table_name="vectors", ) print('delete_response = ', delete_response) ``` #### Important Considerations 1. **Pre-warming Requirement**: - New indices start “cold” and require warming for optimal performance. - Initial queries will be slower until the index is loaded into memory. - Implement explicit pre-warming in production. - Warming must be repeated after system restarts. 2. **Resource Usage**: - Index creation is CPU and memory intensive. - Memory usage scales with dataset size and the `m` parameter. - Create indices during off-peak hours. 3. **Performance Tuning**: - **HNSW Parameters**: - `m`: 16-64 (higher = better quality, more memory) - `ef_construction`: 64-100 (higher = better quality, longer build time) - **Distance Measures**: - `cosine_distance`: Best for normalized vectors (most common) - `l2_distance`: Better for absolute distances - `max_inner_product`: Optimized for dot product similarity ### System Updates and Maintenance #### Version Management **Check Current R2R Version:** ```bash r2r version ``` #### Update Process 1. **Prepare for Update** ```bash # Check current versions r2r version r2r db current # Generate system report (optional) r2r generate-report ``` 2. **Stop Running Services** ```bash r2r docker-down ``` 3. **Update R2R** ```bash r2r update ``` 4. **Update Database** ```bash r2r db upgrade ``` 5. **Restart Services** ```bash r2r serve --docker [additional options] ``` #### Database Migration Management R2R uses database migrations to manage schema changes. **Check Current Migration:** ```bash r2r db current ``` **Apply Migrations:** ```bash r2r db upgrade ``` ### Managing Multiple Environments Use different project names and schemas for different environments. **Example:** ```bash # Development export R2R_PROJECT_NAME=r2r_dev r2r serve --docker --project-name r2r-dev # Staging export R2R_PROJECT_NAME=r2r_staging r2r serve --docker --project-name r2r-staging # Production export R2R_PROJECT_NAME=r2r_prod r2r serve --docker --project-name r2r-prod ``` ### Troubleshooting If issues occur: 1. **Generate a System Report** ```bash r2r generate-report ``` 2. **Check Container Health** ```bash r2r docker-down r2r serve --docker ``` 3. **Review Database State** ```bash r2r db current r2r db history ``` 4. **Roll Back if Needed** ```bash r2r db downgrade --revision ``` ### Scaling Strategies #### Horizontal Scaling For applications serving many users: 1. **Load Balancing** - Deploy multiple R2R instances behind a load balancer. - Each instance handles a subset of users. 2. **Sharding** - Shard by `user_id` for large multi-user deployments. - Each shard handles a subset of users, maintaining performance with millions of documents. #### Vertical Scaling For applications requiring large single-user searches: 1. **Cloud Provider Solutions** - **AWS RDS**: Supports up to 1 billion vectors per instance. - **Example Instance Types**: - `db.r6g.16xlarge`: Suitable for up to 100M vectors. - `db.r6g.metal`: Can handle 1B+ vectors. 2. **Memory Optimization** ```python # Optimize for large vector collections client.indices.create( table_name="vectors", index_method="hnsw", index_arguments={ "m": 32, # Increased for better performance "ef_construction": 80 # Balanced for large collections } ) ``` #### Multi-User Considerations 1. **Filtering Optimization** ```python # Efficient per-user search response = client.retrieval.search( "query", search_settings={ "filters": { "user_id": {"$eq": "current_user_id"} } } ) ``` 2. **Collection Management** - Group related documents into collections. - Enable efficient access control. - Optimize search scope. 3. **Resource Allocation** - Monitor per-user resource usage. - Implement usage quotas if needed. - Consider dedicated instances for power users. #### Performance Monitoring Monitor the following metrics to inform scaling decisions: 1. **Query Performance** - Average query latency per user. - Number of vectors searched per query. - Cache hit rates. 2. **System Resources** - Memory usage per instance. - CPU utilization. - Storage growth rate. 3. **User Patterns** - Number of active users. - Query patterns and peak usage times. - Document count per user. ### Performance Considerations When configuring embeddings in R2R, consider these optimization strategies: 1. **Batch Size Optimization**: - Larger batch sizes improve throughput but increase latency. - Consider provider-specific rate limits when setting batch size. - Balance memory usage with processing speed. 2. **Concurrent Requests**: - Adjust `concurrent_request_limit` based on provider capabilities. - Monitor API usage and adjust limits accordingly. - Implement local caching for frequently embedded texts. 3. **Model Selection**: - Balance embedding dimension size with accuracy requirements. - Consider cost per token for different providers. - Evaluate multilingual requirements when choosing models. 4. **Resource Management**: - Monitor memory usage with large batch sizes. - Implement appropriate error handling and retry strategies. - Consider implementing local model fallbacks for critical systems. ### Additional Resources -

This guide covers basic usage, advanced features, security considerations, and troubleshooting. For detailed configuration, refer to the [Authentication Configuration Documentation](https://r2r-docs.sciphi.ai/documentation/configuration/auth) and the [User API Reference](https://r2r-docs.sciphi.ai/api-and-sdks/users/users). **Default Behavior**: When `require_authentication` is set to `false` (default in `r2r.toml`), unauthenticated requests use default admin credentials. Use caution in production environments. ### Basic Usage #### User Registration and Login **Python Example:** ```python from r2r import R2RClient client = R2RClient("http://localhost:7272") # Replace with your R2R deployment URL # Register a new user user_result = client.users.create("user1@test.com", "password123") print(user_result) # {'results': {'email': 'user1@test.com', 'id': 'bf417057-f104-4e75-8579-c74d26fcbed3', ...}} # Login immediately (assuming email verification is disabled) login_result = client.users.login("user1@test.com", "password123") print(login_result) # {'results': {'access_token': {...}, 'refresh_token': {...}}} ``` #### Email Verification (Optional) If email verification is enabled: ```python # Verify email verify_result = client.users.verify_email("verification_code_here") print(verify_result) # {"results": {"message": "Email verified successfully"}} ``` #### Token Refresh Refresh an expired access token: ```python refresh_result = client.users.refresh_access_token("YOUR_REFRESH_TOKEN") print(refresh_result) # {'access_token': {...}, 'refresh_token': {...}} ``` #### User-Specific Search Authenticated searches are filtered based on the user's permissions. **Curl Example:** ```bash curl -X POST http://localhost:7272/v3/retrieval/search \ -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \ -H "Content-Type: application/json" \ -d '{ "query": "Who was Aristotle" }' ``` **Sample Output:** ```json { "results": { "chunk_search_results": [], "kg_search_results": [] } } ``` > *Search results are empty for a new user.* #### User Logout Invalidate the current access token. **Curl Example:** ```bash curl -X POST http://localhost:7272/v3/users/logout \ -H "Authorization: Bearer YOUR_ACCESS_TOKEN" ``` **Sample Output:** ```json { "results": {"message": "Logged out successfully"} } ``` ### Advanced Authentication Features #### Password Management Users can change their passwords and request password resets. **Python Example:** ```python # Change password change_password_result = client.users.change_password("password123", "new_password") print(change_password_result) # {"results": {"message": "Password changed successfully"}} # Request password reset reset_request_result = client.users.request_password_reset("user@example.com") print(reset_request_result) # {"results": {"message": "If the email exists, a reset link has been sent"}} # Confirm password reset reset_confirm_result = client.users.confirm_password_reset("reset_token_here", "new_password") print(reset_confirm_result) # {"results": {"message": "Password reset successfully"}} ``` #### User Profile Management Users can view and update their profiles. **Python Example:** ```python # Update user profile (requires login) update_result = client.users.update_user(name="John Doe", bio="R2R enthusiast") print(update_result) # {'results': {'email': 'user1@test.com', 'id': '76eea168-9f98-4672-af3b-2c26ec92d7f8', ...}} ``` #### Account Deletion Users can delete their accounts. **Python Example:** ```python # Delete account (requires password confirmation) user_id = register_response["results"]["id"] # Use the actual user ID delete_result = client.delete_user(user_id, "password123") print(delete_result) # {'results': {'message': 'User account deleted successfully'}} ``` #### Logout To end a user session: ```python # Logout logout_result = client.users.logout() print(f"Logout Result:\n{logout_result}") # {'results': {'message': 'Logged out successfully'}} ``` ### Superuser Capabilities and Default Admin Creation #### Superuser Capabilities Superusers have elevated privileges, enabling them to: 1. **User Management**: View, modify, and delete user accounts. 2. **System-wide Document Access**: Access and manage all documents. 3. **Analytics and Observability**: Access system-wide analytics and logs. 4. **Configuration Management**: Modify system configurations and settings. #### Default Admin Creation R2R automatically creates a default admin user during initialization via the `R2RAuthProvider` class. **Configuration:** ```toml [auth] provider = "r2r" access_token_lifetime_in_minutes = 60 refresh_token_lifetime_in_days = 7 require_authentication = true require_email_verification = false default_admin_email = "admin@example.com" default_admin_password = "change_me_immediately" ``` - **`require_authentication`**: Set to `false` for development/testing; `true` for production. - **`require_email_verification`**: Set to `false` by default; consider enabling for production. #### Accessing Superuser Features Authenticate as the default admin or another superuser to access superuser features. **Python Example:** ```python from r2r import R2RClient client = R2RClient("http://localhost:7272") # Login as admin login_result = client.users.login("admin@example.com", "change_me_immediately") # Access superuser features users_overview = client.users.list() print(users_overview) # Access system-wide logs logs = client.logs() print(logs) # Perform analytics analytics_result = client.analytics( {"all_latencies": "search_latency"}, {"search_latencies": ["basic_statistics", "search_latency"]} ) print(analytics_result) ``` ### Security Considerations for Superusers When using superuser capabilities: 1. **Limit Superuser Access**: Only grant to trusted individuals. 2. **Use Strong Passwords**: Ensure superuser accounts use strong, unique passwords. 3. **Enable Authentication and Verification**: Set `require_authentication` and `require_email_verification` to `true` in production. 4. **Audit Superuser Actions**: Regularly review logs of superuser activities. 5. **Rotate Credentials**: Periodically update superuser credentials, including the default admin password. ### Security Considerations When implementing user authentication, consider the following security best practices: 1. **Use HTTPS**: Always use HTTPS in production to encrypt data in transit. 2. **Implement Rate Limiting**: Protect against brute-force attacks by limiting login attempts. 3. **Use Secure Password Hashing**: R2R uses bcrypt for password hashing by default. 4. **Implement Multi-Factor Authentication (MFA)**: Add MFA for an extra layer of security. 5. **Regular Security Audits**: Conduct regular security audits of your authentication system. ### Customizing Authentication R2R’s authentication system is flexible and can be customized to fit your specific needs: 1. **Custom User Fields**: Extend the User model to include additional fields. 2. **OAuth Integration**: Integrate with third-party OAuth providers for social login. 3. **Custom Password Policies**: Implement custom password strength requirements. 4. **User Roles and Permissions**: Implement a role-based access control system. ### Troubleshooting **Common Issues and Solutions:** 1. **Login Fails After Registration**: - Ensure email verification is completed if enabled. 2. **Token Refresh Fails**: - Check if the refresh token has expired; the user may need to log in again. 3. **Unable to Change Password**: - Verify that the current password is correct. ### Conclusion R2R provides a comprehensive set of user authentication and management features, allowing developers to implement secure and user-friendly applications. By leveraging these capabilities, you can implement robust user authentication, document management, and access control in your R2R-based projects. For more advanced use cases or custom implementations, refer to the R2R documentation or reach out to the community for support. --- ## Collections ### Introduction A **collection** in R2R is a logical grouping of users and documents that allows for efficient access control and organization. Collections enable you to manage permissions and access to documents at a group level, rather than individually. R2R provides robust document collection management, allowing developers to implement efficient access control and organization of users and documents. **Note**: Collection permissioning in R2R is under development and may continue evolving in future releases. ### Basic Usage #### Collection CRUD Operations **Creating a Collection:** ```python from r2r import R2RClient client = R2RClient("http://localhost:7272") # Replace with your R2R deployment URL # Create a new collection collection_result = client.collections.create("Marketing Team", "Collection for marketing department") print(f"Collection creation result: {collection_result}") # {'results': {'collection_id': '123e4567-e89b-12d3-a456-426614174000', 'name': 'Marketing Team', 'description': 'Collection for marketing department', ...}} ``` **Retrieving Collection Details:** ```python collection_id = '123e4567-e89b-12d3-a456-426614174000' # Use the actual collection_id collection_details = client.collections.retrieve(collection_id) print(f"Collection details: {collection_details}") # {'results': {'collection_id': '123e4567-e89b-12d3-a456-426614174000', 'name': 'Marketing Team', 'description': 'Collection for marketing department', ...}} ``` **Updating a Collection:** ```python update_result = client.collections.update( collection_id, name="Updated Marketing Team", description="New description for marketing team" ) print(f"Collection update result: {update_result}") # {'results': {'collection_id': '123e4567-e89b-12d3-a456-426614174000', 'name': 'Updated Marketing Team', 'description': 'New description for marketing team', ...}} ``` **Deleting a Collection:** ```python client.collections.delete(collection_id) ``` ### User Management in Collections #### Adding a User to a Collection ```python user_id = '456e789f-g01h-34i5-j678-901234567890' # Valid user ID collection_id = '123e4567-e89b-12d3-a456-426614174000' # Valid collection ID add_user_result = client.collections.add_user(user_id, collection_id) print(f"Add user to collection result: {add_user_result}") # {'results': {'message': 'User successfully added to the collection'}} ``` #### Removing a User from a Collection ```python remove_user_result = client.collections.remove_user(user_id, collection_id) print(f"Remove user from collection result: {remove_user_result}") # {'results': None} ``` #### Listing Users in a Collection ```python users_in_collection = client.collections.list_users(collection_id) print(f"Users in collection: {users_in_collection}") # {'results': [{'user_id': '456e789f-g01h-34i5-j678-901234567890', 'email': 'user@example.com', 'name': 'John Doe', ...}, ...]} ``` #### Getting Collections for a User ```python user_collections = client.user.list_collections(user_id) print(f"User's collections: {user_collections}") # {'results': [{'collection_id': '123e4567-e89b-12d3-a456-426614174000', 'name': 'Updated Marketing Team', ...}, ...]} ``` ### Document Management in Collections #### Assigning a Document to a Collection ```python document_id = '789g012j-k34l-56m7-n890-123456789012' # Valid document ID assign_doc_result = client.collections.add_document(collection_id, document_id) print(f"Assign document to collection result: {assign_doc_result}") # {'results': {'message': 'Document successfully assigned to the collection'}} ``` #### Removing a Document from a Collection ```python remove_doc_result = client.collections.remove_document(collection_id, document_id) print(f"Remove document from collection result: {remove_doc_result}") # {'results': {'message': 'Document successfully removed from the collection'}} ``` #### Listing Documents in a Collection ```python docs_in_collection = client.collections.list_documents(collection_id) print(f"Documents in collection: {docs_in_collection}") # {'results': [{'document_id': '789g012j-k34l-56m7-n890-123456789012', 'title': 'Marketing Strategy 2024', ...}, ...]} ``` #### Getting Collections for a Document ```python document_collections = client.documents.list_collections(document_id) print(f"Document's collections: {document_collections}") # {'results': [{'collection_id': '123e4567-e89b-12d3-a456-426614174000', 'name': 'Updated Marketing Team', ...}, ...]} ``` ### Advanced Collection Management #### Generating Synthetic Descriptions Generate a description for a collection using an LLM. ```python update_result = client.collections.update( collection_id, generate_description=True ) print(f"Collection update result: {update_result}") # {'results': {'collection_id': '123e4567-e89b-12d3-a456-426614174000', 'name': 'Updated Marketing Team', 'description': 'A rich description...', ...}} ``` #### Collection Overview Get an overview of collections, including user and document counts. ```python collections_list = client.collections.list() print(f"Collections overview: {collections_list}") # {'results': [{'collection_id': '123e4567-e89b-12d3-a456-426614174000', 'name': 'Updated Marketing Team', 'description': 'New description...', 'user_count': 5, 'document_count': 10, ...}, ...]} ``` ### Pagination and Filtering Many collection-related methods support pagination and filtering. **Examples:** ```python # List collections with pagination paginated_collections = client.collections.list(offset=10, limit=20) # Get users in a collection with pagination paginated_users = client.collections.list_users(collection_id, offset=5, limit=10) # Get documents in a collection with pagination paginated_docs = client.collections.list_documents(collection_id, offset=0, limit=50) # Get specific collections by IDs specific_collections = client.collections.list(collection_ids=['id1', 'id2', 'id3']) ``` ### Security Considerations When implementing collection permissions, consider the following security best practices: 1. **Least Privilege Principle**: Assign minimum necessary permissions to users and collections. 2. **Regular Audits**: Periodically review collection memberships and document assignments. 3. **Access Control**: Ensure only authorized users (e.g., admins) can perform collection management operations. 4. **Logging and Monitoring**: Implement comprehensive logging for all collection-related actions. ### Customizing Collection Permissions While R2R’s current collection system follows a flat hierarchy, you can build more complex permission structures: 1. **Custom Roles**: Implement application-level roles within collections (e.g., collection admin, editor, viewer). 2. **Hierarchical Collections**: Create a hierarchy by establishing parent-child relationships between collections in your application logic. 3. **Permission Inheritance**: Implement rules for permission inheritance based on collection memberships. ### Troubleshooting **Common Issues and Solutions:** 1. **Unable to Create/Modify Collections**: - Ensure the user has superuser privileges. 2. **User Not Seeing Collection Content**: - Verify that the user is correctly added to the collection. - Ensure documents are properly assigned. 3. **Performance Issues with Large Collections**: - Use pagination when retrieving users or documents. - Consider splitting large collections. ### Conclusion R2R’s collection permissioning system provides a foundation for implementing sophisticated access control in your applications. As the feature set evolves, more advanced capabilities will become available. Regularly update your practices based on the latest R2R documentation. ### Next Steps - Explore [GraphRAG](https://r2r-docs.sciphi.ai/cookbooks/graphrag) for advanced features. - Learn about [hybrid search](https://r2r-docs.sciphi.ai/cookbooks/hybrid-search) integration. - Discover more about [observability](https://r2r-docs.sciphi.ai/cookbooks/observability). - Set up [orchestration](https://r2r-docs.sciphi.ai/cookbooks/orchestration) for large-scale processing. --- ## Telemetry R2R uses telemetry to collect **anonymous** usage information.

This data helps understand how R2R is used, prioritize new features and bug fixes, and improve overall performance and stability. ### Disabling Telemetry To opt out of telemetry, set an environment variable: ```bash export TELEMETRY_ENABLED=false ``` **Valid Values**: `false`, `0`, `f` When telemetry is disabled, no events are captured. ### Collected Information Our telemetry system collects basic, anonymous information such as: - **Feature Usage**: Which features are being used and their frequency. - **Performance Metrics**: Query latencies, system resource usage. - **Error Logs**: Information about errors and exceptions. ### Telemetry Data Storage *Details about telemetry data storage are not provided in the original document.* ### Why We Collect Telemetry Telemetry data helps us: 1. Understand which features are most valuable to users. 2. Identify areas for improvement. 3. Prioritize development efforts. 4. Enhance R2R’s overall performance and stability. We appreciate your participation in our telemetry program, as it directly contributes to making R2R better for everyone. ### Conclusion Telemetry in R2R provides valuable insights into system usage and performance, enabling continuous improvement. Users concerned about privacy can easily disable telemetry by setting the appropriate environment variable. --- ## Embedding ### Embedding System R2R uses embeddings as the foundation for semantic search and similarity matching capabilities. The embedding system converts text into high-dimensional vectors that capture semantic meaning, enabling powerful search and retrieval operations. R2R leverages **LiteLLM** to route embedding requests due to their provider flexibility. Read more about [LiteLLM here](https://docs.litellm.ai/). ### Embedding Configuration Customize the embedding system through the `embedding` section in your `r2r.toml` file, along with corresponding environment variables for sensitive information. **Example: `r2r.toml`** ```toml [embedding] provider = "litellm" # defaults to "litellm" base_model = "openai/text-embedding-3-small" # defaults to "openai/text-embedding-3-large" base_dimension = 512 # defaults to 3072 batch_size = 512 # defaults to 128 rerank_model = "BAAI/bge-reranker-v2-m3" # defaults to None concurrent_request_limit = 256 # defaults to 256 ``` **Environment Variables:** - `OPENAI_API_KEY` - `OPENAI_API_BASE` - `HUGGINGFACE_API_KEY` - `HUGGINGFACE_API_BASE` - `ANTHROPIC_API_KEY` - `COHERE_API_KEY` - `OLLAMA_API_KEY` - `BEDROCK_API_KEY` - `VERTEX_AI_API_KEY` - `VOYAGE_AI_API_KEY` ### Advanced Embedding Features in R2R #### Batched Processing R2R implements intelligent batching for embedding operations to optimize throughput and, in some cases, cost. **Python Example:** ```python class EmbeddingProvider: async def embed_texts(self, texts: List[str]) -> List[List[float]]: batches = [texts[i:i + self.batch_size] for i in range(0, len(texts), self.batch_size)] embeddings = [] for batch in batches: batch_embeddings = await self._process_batch(batch) embeddings.extend(batch_embeddings) return embeddings ``` #### Concurrent Request Management The system manages requests with rate limiting and concurrency control. 1. **Rate Limiting**: Prevents API throttling through intelligent request scheduling. 2. **Concurrent Processing**: Manages multiple embedding requests efficiently. 3. **Error Handling**: Implements retry logic with exponential backoff. ### Performance Considerations When configuring embeddings in R2R, consider these optimization strategies: 1. **Batch Size Optimization**: - Larger batch sizes improve throughput but increase latency. - Consider provider-specific rate limits when setting batch size. - Balance memory usage with processing speed. 2. **Concurrent Requests**: - Adjust `concurrent_request_limit` based on provider capabilities. - Monitor API usage and adjust limits accordingly. - Implement local caching for frequently embedded texts. 3. **Model Selection**: - Balance embedding dimension size with accuracy requirements. - Consider cost per token for different providers. - Evaluate multilingual requirements when choosing models. 4. **Resource Management**: - Monitor memory usage with large batch sizes. - Implement appropriate error handling and retry strategies. - Consider implementing local model fallbacks for critical systems. ### Supported LiteLLM Providers R2R supports multiple LiteLLM providers: - **OpenAI** - **Azure** - **Anthropic** - **Cohere** - **Ollama** - **HuggingFace** - **Bedrock** - **Vertex AI** - **Voyage AI** **Example Configuration:** ```toml [embedding] provider = "litellm" base_model = "openai/text-embedding-3-small" base_dimension = 512 # Environment Variables export OPENAI_API_KEY=your_openai_key # Set other environment variables as needed ``` **Supported Models:** - `openai/text-embedding-3-small` - `openai/text-embedding-3-large` - `openai/text-embedding-ada-002` ### Performance Considerations 1. **Batch Size Optimization**: - Larger batches improve throughput but may increase latency. - Balance batch size with memory and processing speed. 2. **Concurrent Requests**: - Adjust based on provider capabilities. - Monitor and optimize based on API usage. 3. **Model Selection**: - Choose models that fit your domain and accuracy needs. - Consider cost implications of different models. ### Conclusion R2R’s embedding system, powered by LiteLLM, offers flexible and powerful semantic search capabilities. By optimizing batch sizes, managing concurrent requests, and selecting appropriate models, you can ensure efficient and accurate embeddings tailored to your application's needs. --- ## Prompts ### Prompt Management in R2R R2R provides a flexible system for managing prompts, allowing you to create, update, retrieve, and delete prompts dynamically. This system is crucial for customizing the behavior of language models and ensuring consistent interactions across your application. ### Default Prompts R2R comes with a set of default prompts loaded from YAML files located in the [`py/core/providers/database/prompts`](https://github.com/SciPhi-AI/R2R/tree/main/py/core/providers/database/prompts) directory. These prompts serve as starting points for various tasks. **Example: `rag.yaml`** ```yaml rag: template: > ## Task: Answer the query given immediately below given the context which follows later. Use line item references like [1], [2], ... to refer to specifically numbered items in the provided context.

This leverages both a Postgres database and YAML files for flexibility and persistence. **Key Features:** 1. **Database Storage**: Prompts are stored in a Postgres table for efficient querying and updates. 2. **YAML File Support**: Prompts can be loaded from YAML files, facilitating version control and distribution. 3. **In-Memory Cache**: Prompts are kept in memory for fast access during runtime. ### Prompt Structure Each prompt in R2R consists of: - **Name**: A unique identifier for the prompt. - **Template**: The actual text of the prompt, which may include placeholders for dynamic content. - **Input Types**: A dictionary specifying the expected types for any dynamic inputs to the prompt. ### Managing Prompts R2R provides several endpoints and SDK methods for managing prompts: #### Adding a Prompt ```python from r2r import R2RClient client = R2RClient() response = client.prompts.add_prompt( name="my_new_prompt", template="Hello, {name}! Welcome to {service}.", input_types={"name": "str", "service": "str"} ) ``` #### Updating a Prompt ```python response = client.prompts.update_prompt( name="my_existing_prompt", template="Updated template: {variable}", input_types={"variable": "str"} ) ``` #### Retrieving a Prompt ```python response = client.prompts.get_prompt( prompt_name="my_prompt", inputs={"variable": "example"}, prompt_override="Optional override text" ) ``` Refer to the [Prompt API Reference](https://r2r-docs.sciphi.ai/api-and-sdks/prompts) for more details. ### Security Considerations Access to prompt management functions is restricted to superusers to prevent unauthorized modifications to system prompts. Ensure only trusted administrators have superuser access to your R2R deployment. ### Conclusion R2R’s prompt management system offers powerful and flexible control over language model behavior. By effectively managing prompts, you can create dynamic, context-aware, and maintainable AI-powered features tailored to your application's needs. --- ## RAG ### RAG Customization RAG (Retrieval-Augmented Generation) in R2R can be extensively customized to suit various use cases. The main components for customization are: 1. **Generation Configuration**: Control the language model’s behavior. 2. **Search Settings**: Fine-tune the retrieval process. 3. **Task Prompt Override**: Customize the system prompt for specific tasks. #### LLM Provider Configuration Refer to the [LLM Configuration](https://r2r-docs.sciphi.ai/documentation/configuration/llm) page for detailed information. #### Retrieval Configuration Refer to the [Retrieval Configuration](https://r2r-docs.sciphi.ai/documentation/configuration/retrieval/overview) page for detailed information. ### Combining LLM and Retrieval Configuration for RAG The `rag_generation_config` parameter allows you to customize the language model’s behavior. Default settings are set on the server-side using `r2r.toml`. These settings can be overridden at runtime. **Python Example:** ```python from r2r import R2RClient client = R2RClient() response = client.retrieval.rag( "Who was Aristotle?", rag_generation_config={ "model": "anthropic/claude-3-haiku-20240307", "temperature": 0.7, }, search_settings={ "use_semantic_search": True, "limit": 20, "use_hybrid_search": True } ) ``` ### RAG Prompt Override For specialized tasks, override the default RAG task prompt at runtime. **Python Example:** ```python task_prompt_override = """You are an AI assistant specializing in quantum computing. Your task is to provide a concise summary of the latest advancements in the field, focusing on practical applications and breakthroughs from the past year.""" response = client.retrieval.rag( "What are the latest advancements in quantum computing?", rag_generation_config=rag_generation_config, task_prompt_override=task_prompt_override ) ``` ### Agent-based Interaction R2R supports multi-turn conversations and complex query processing through its agent endpoint. **Python Example:** ```python from r2r import R2RClient client = R2RClient("http://localhost:7272") messages = [ {"role": "system", "content": "You are a helpful AI assistant."}, {"role": "user", "content": "What are the key differences between quantum and classical computing?"} ] response = client.retrieval.agent( messages=messages, vector_search_settings=vector_search_settings, graph_settings=graph_settings, rag_generation_config=rag_generation_config, ) ``` ### Conclusion By leveraging R2R’s RAG customization options, you can fine-tune retrieval and generation processes to best suit your specific use case and requirements, enhancing the overall performance and relevance of your AI-powered features. --- ## Graphs ### Graphs R2R supports robust knowledge graph functionality to enhance document understanding and retrieval.

You can use the `.env` file method described earlier. ```bash cp .env.example .env # Edit the .env file with your specific configurations nano .env ``` > **Tip**: Use a text editor of your choice (e.g., `vim`, `nano`) to edit the `.env` file. ### **Step 3: Build Docker Images** Build the Docker images using the provided `Dockerfile` and `Dockerfile.unstructured`. ```bash # Build the R2R application image docker build -t r2r-app -f Dockerfile . # Build the Unstructured service image docker build -t unstructured-service -f Dockerfile.unstructured . ``` > **Note**: Ensure Docker is running before executing these commands. The build process may take several minutes. ### **Step 4: Deploy Services with Docker Compose** Use Docker Compose to deploy all services as defined in `compose.full_with_replicas.yaml`. ```bash docker-compose -f compose.full_with_replicas.yaml up -d ``` > **Flags Explained**: > - `-f compose.full_with_replicas.yaml`: Specifies the Docker Compose file to use. > - `up`: Builds, (re)creates, starts, and attaches to containers for a service. > - `-d`: Runs containers in the background (detached mode). > **Monitoring Deployment**: > You can monitor the status of your services using: > ```bash > docker-compose -f compose.full_with_replicas.yaml ps > ``` --- ## **Initial Setup Steps** After deploying the services, perform the following initial setup steps to configure Hatchet and R2R. ### **Creating the Hatchet API Token** The `setup-token` service is responsible for generating the Hatchet API token, which R2R uses to communicate with Hatchet. 1. **Ensure `setup-token` Service is Running** The `setup-token` service should have already been started by Docker Compose. Verify its status: ```bash docker-compose -f compose.full_with_replicas.yaml ps ``` 2. **Verify Token Generation** The token is stored in the `hatchet_api_key` volume. To retrieve the token: ```bash docker exec -it cat /hatchet_api_key/api_key.txt ``` Replace `` with the actual container name, which can be found using: ```bash docker-compose -f compose.full_with_replicas.yaml ps ``` 3. **Set Hatchet API Token Environment Variable** Ensure that the `HATCHET_CLIENT_TOKEN` environment variable is correctly set in the `r2r` service. This is handled automatically by the `r2r` service command, which reads the token from the `hatchet_api_key` volume. --- ## **Accessing R2R and Hatchet Dashboard** ### **R2R API** - **URL**: `http://:7272` - **Health Check Endpoint**: `http://:7272/v3/health` ### **Hatchet Dashboard** - **URL**: `http://:7274` ### **R2R Dashboard** - **URL**: `http://:7273` ### **Nginx Reverse Proxy** - **URL**: `http://:7280` > **Note**: Replace `` with your server's actual IP address or domain name. Ensure that the specified ports are open and accessible. --- ## **Configuring Nginx as a Reverse Proxy** Nginx serves as a reverse proxy, directing incoming traffic to the appropriate services based on the configuration in `nginx.conf`. ### **Sample `nginx.conf`** Ensure you have an `nginx.conf` file in your project root with appropriate proxy settings. Here's a basic example: ```nginx worker_processes 1; events { worker_connections 1024; } http { server { listen 80; location /api/ { proxy_pass http://r2r:7272/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } location /dashboard/ { proxy_pass http://r2r-dashboard:3000/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } location /hatchet-dashboard/ { proxy_pass http://hatchet-dashboard:80/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } location / { proxy_pass http://nginx:80/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } } } ``` > **Customization**: Modify `nginx.conf` according to your routing needs. Ensure that service names in `proxy_pass` match the service names defined in Docker Compose. ### **Reloading Nginx Configuration** After updating `nginx.conf`, reload Nginx to apply changes: ```bash docker-compose -f compose.full_with_replicas.yaml exec nginx nginx -s reload ``` --- ## **Configuring R2R** R2R's behavior is controlled via the `r2r.toml` file. Ensure this file is correctly configured before starting the services. ### **Sample `r2r.toml`** Below is a sample `r2r.toml` with essential configurations: ```toml [app] default_max_documents_per_user = 100 default_max_chunks_per_user = 10000 default_max_collections_per_user = 10 [agent] rag_agent_static_prompt = "rag_agent" tools = ["search_file_knowledge"] [agent.generation_config] model = "openai/gpt-4.1" [auth] provider = "r2r" access_token_lifetime_in_minutes = 60 refresh_token_lifetime_in_days = 7 require_authentication = false require_email_verification = false default_admin_email = "admin@example.com" default_admin_password = "change_me_immediately" [completion] provider = "litellm" concurrent_request_limit = 64 [completion.generation_config] model = "openai/gpt-4.1" temperature = 0.1 top_p = 1 max_tokens_to_sample = 1024 stream = false add_generation_kwargs = { } [crypto] provider = "bcrypt" [database] provider = "postgres" default_collection_name = "Default" default_collection_description = "Your default collection." batch_size = 256 [database.graph_creation_settings] graph_entity_description_prompt = "graph_entity_description" entity_types = [] relation_types = [] fragment_merge_count = 1 max_knowledge_relationships = 100 max_description_input_length = 65536 generation_config = { model = "openai/gpt-4.1-mini" } [database.graph_enrichment_settings] max_summary_input_length = 65536 generation_config = { model = "openai/gpt-4.1-mini" } leiden_params = {} [database.graph_search_settings] generation_config = { model = "openai/gpt-4.1-mini" } [database.limits] global_per_min = 300 monthly_limit = 10000 [database.route_limits] "/v3/retrieval/search" = { route_per_min = 120 } "/v3/retrieval/rag" = { route_per_min = 30 } [embedding] provider = "litellm" base_model = "openai/text-embedding-3-small" base_dimension = 512 batch_size = 128 concurrent_request_limit = 256 quantization_settings = { quantization_type = "FP32" } [file] provider = "postgres" [ingestion] provider = "r2r" chunking_strategy = "recursive" chunk_size = 1024 chunk_overlap = 512 excluded_parsers = [] document_summary_model = "openai/gpt-4.1-mini" [ingestion.chunk_enrichment_settings] enable_chunk_enrichment = false strategies = ["semantic", "neighborhood"] forward_chunks = 3 backward_chunks = 3 semantic_neighbors = 10 semantic_similarity_threshold = 0.7 generation_config = { model = "openai/gpt-4.1-mini" } [ingestion.extra_parsers] pdf = "zerox" [orchestration] provider = "simple" [prompt] provider = "r2r" [email] provider = "console_mock" ``` ### **Key Configuration Sections** - **[app]**: Sets default limits for documents, chunks, and collections per user. - **[agent]**: Configures the RAG agent, specifying tools and generation models. - **[auth]**: Authentication settings, including token lifetimes and default admin credentials. - **[completion]**: Settings for text completion, including provider and generation configurations. - **[crypto]**: Cryptographic provider. - **[database]**: PostgreSQL settings, knowledge graph configurations, and rate limits. - **[embedding]**: Embedding provider configurations. - **[file]**: File storage provider. - **[ingestion]**: Data ingestion settings, including chunking strategies and enrichment configurations. - **[logging]**: Logging provider and tables. - **[orchestration]**: Orchestration provider settings. - **[prompt]**: Prompt management provider. - **[email]**: Email provider settings. > **Customization**: Adjust the `r2r.toml` file according to your specific requirements. Ensure that all paths, models, and service URLs match your deployment environment. --- ## **Maintenance and Scaling** ### **Vector Indices** **Do You Need Vector Indices?** Vector indices enhance search capabilities but are not necessary for all deployments, especially in multi-user environments with user-specific filtering. **When to Implement Vector Indices:** - Large-scale searches across hundreds of thousands of documents. - When query latency becomes a bottleneck. - Supporting cross-user search functionalities. **Vector Index Management:** R2R supports various indexing methods, with HNSW (Hierarchical Navigable Small World) recommended for most use cases. **Example: Creating and Deleting a Vector Index** ```python from r2r import R2RClient client = R2RClient() # Create vector index create_response = client.indices.create( { "table_name": "vectors", "index_method": "hnsw", "index_measure": "cosine_distance", "index_arguments": { "m": 16, "ef_construction": 64 }, } ) # List existing indices indices = client.indices.list() # Delete an index delete_response = client.indices.delete( index_name="ix_vector_cosine_ops_hnsw__20241021211541", table_name="vectors", ) print('delete_response = ', delete_response) ``` **Important Considerations:** 1. **Pre-warming**: New indices start "cold" and require warming for optimal performance. 2. **Resource Usage**: Index creation is CPU and memory-intensive. Perform during off-peak hours. 3. **Performance Tuning**: - **HNSW Parameters**: - `m`: 16-64 (higher = better quality, more memory) - `ef_construction`: 64-100 (higher = better quality, longer build time) - **Distance Measures**: - `cosine_distance`: Best for normalized vectors. - `l2_distance`: Better for absolute distances. - `max_inner_product`: Optimized for dot product similarity. ### **System Updates and Maintenance** **Version Management** Check the current R2R version: ```bash docker-compose -f compose.full_with_replicas.yaml exec r2r r2r version ``` **Update Process** 1. **Prepare for Update** ```bash docker-compose -f compose.full_with_replicas.yaml exec r2r r2r version docker-compose -f compose.full_with_replicas.yaml exec r2r r2r db current docker-compose -f compose.full_with_replicas.yaml exec r2r r2r generate-report ``` 2. **Stop Running Services** ```bash docker-compose -f compose.full_with_replicas.yaml down ``` 3. **Update R2R** ```bash docker-compose -f compose.full_with_replicas.yaml pull docker-compose -f compose.full_with_replicas.yaml up -d --build ``` 4. **Update Database** ```bash docker-compose -f compose.full_with_replicas.yaml exec r2r r2r db upgrade ``` 5. **Restart Services** ```bash docker-compose -f compose.full_with_replicas.yaml up -d ``` **Database Migration Management** Check current migration: ```bash docker-compose -f compose.full_with_replicas.yaml exec r2r r2r db current ``` Apply migrations: ```bash docker-compose -f compose.full_with_replicas.yaml exec r2r r2r db upgrade ``` Rollback if necessary: ```bash docker-compose -f compose.full_with_replicas.yaml exec r2r r2r db downgrade --revision ``` ### **Managing Multiple Environments** Use different project names and schemas for development, staging, and production environments. **Example:** ```bash # Development export R2R_PROJECT_NAME=r2r_dev docker-compose -f compose.full_with_replicas.yaml up -d # Staging export R2R_PROJECT_NAME=r2r_staging docker-compose -f compose.full_with_replicas.yaml up -d # Production export R2R_PROJECT_NAME=r2r_prod docker-compose -f compose.full_with_replicas.yaml up -d ``` --- ## **Security Considerations** Ensuring the security of your deployment is paramount. Follow these best practices to secure your R2R deployment. 1. **Secure Environment Variables** - Store sensitive information like API keys and passwords securely. - Avoid hardcoding secrets in configuration files. Use environment variables or secret management tools. 2. **Use HTTPS** - Configure Nginx to use HTTPS with valid SSL certificates to encrypt data in transit. - Update `nginx.conf` to include SSL configurations. 3. **Restrict Access to Services** - Limit access to PostgreSQL and RabbitMQ to only necessary services. - Use firewall rules to restrict external access to sensitive ports. 4. **Strong Passwords** - Use strong, unique passwords for all services, especially for PostgreSQL and RabbitMQ. - Regularly update and rotate passwords. 5. **Enable Authentication and Verification** - In `r2r.toml`, set `require_authentication = true` and `require_email_verification = true` for production environments. - Update default admin credentials immediately after deployment. 6. **Rate Limiting** - Configure rate limits in `r2r.toml` to prevent abuse: ```toml [database.route_limits] "/v3/retrieval/search" = { route_per_min = 120 } "/v3/retrieval/rag" = { route_per_min = 30 } ``` 7. **Regular Security Audits** - Periodically review logs and monitor for suspicious activities. - Keep all services and dependencies updated with the latest security patches. 8. **Secure Nginx Configuration** - Ensure Nginx is properly configured to prevent vulnerabilities like open redirects and XSS attacks. - Implement security headers: ```nginx add_header X-Content-Type-Options nosniff; add_header X-Frame-Options DENY; add_header X-XSS-Protection "1; mode=block"; add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always; ``` --- ## **Troubleshooting** Deployments can encounter issues. Below are common problems and their solutions. 1. **Service Not Starting** - **Check Logs**: ```bash docker-compose -f compose.full_with_replicas.yaml logs ``` - **Example**: ```bash docker-compose -f compose.full_with_replicas.yaml logs r2r ``` 2. **Database Connection Issues** - **Verify Environment Variables**: Ensure `R2R_POSTGRES_HOST`, `R2R_POSTGRES_PORT`, `R2R_POSTGRES_USER`, and `R2R_POSTGRES_PASSWORD` are correct. - **Check Service Status**: ```bash docker-compose -f compose.full_with_replicas.yaml ps ``` 3. **Healthchecks Failing** - **Inspect Health Status**: ```bash docker inspect --format='{{json .State.Health}}' ``` - **Restart Services**: ```bash docker-compose -f compose.full_with_replicas.yaml restart ``` 4. **API Not Responding** - **Ensure R2R is Running**: ```bash docker-compose -f compose.full_with_replicas.yaml ps ``` - **Check Network Connectivity**: ```bash docker-compose -f compose.full_with_replicas.yaml exec r2r ping postgres ``` 5. **Token Generation Issues** - **Verify `setup-token` Service Logs**: ```bash docker-compose -f compose.full_with_replicas.yaml logs setup-token ``` - **Ensure `hatchet_api_key` Volume is Mounted Correctly** 6. **Nginx Proxy Issues** - **Check Nginx Configuration**: Ensure `nginx.conf` correctly routes traffic. - **Reload Nginx**: ```bash docker-compose -f compose.full_with_replicas.yaml exec nginx nginx -s reload ``` 7. **Unstructured Service Failures** - **Check Dependencies**: Ensure all system dependencies are installed. - **Inspect Logs**: ```bash docker-compose -f compose.full_with_replicas.yaml logs unstructured ``` --- ## **Conclusion** Deploying R2R involves orchestrating multiple services to work seamlessly together. By following this guide, you should be able to set up a robust and secure R2R deployment tailored to your needs. Remember to regularly update your services, monitor performance, and enforce security best practices to maintain the integrity and efficiency of your R2R application.

================================================ ================================================ FILE: py/core/examples/data/aristotle.txt ================================================ Aristotle[A] (Greek: Ἀριστοτέλης Aristotélēs, pronounced [aristotélɛːs]; 384–322 BC) was an Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science. Little is known about Aristotle's life. He was born in the city of Stagira in northern Greece during the Classical period. His father, Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At 17 or 18, he joined Plato's Academy in Athens and remained there until the age of 37 (c. 347 BC). Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored his son Alexander the Great beginning in 343 BC. He established a library in the Lyceum, which helped him to produce many of his hundreds of books on papyrus scrolls. Though Aristotle wrote many elegant treatises and dialogues for publication, only around a third of his original output has survived, none of it intended for publication. Aristotle provided a complex synthesis of the various philosophies existing prior to him. His teachings and methods of inquiry have had a significant impact across the world, and remain a subject of contemporary philosophical discussion. Aristotle's views profoundly shaped medieval scholarship. The influence of his physical science extended from late antiquity and the Early Middle Ages into the Renaissance, and was not replaced systematically until the Enlightenment and theories such as classical mechanics were developed. He influenced Judeo-Islamic philosophies during the Middle Ages, as well as Christian theology, especially the Neoplatonism of the Early Church and the scholastic tradition of the Catholic Church. Aristotle was revered among medieval Muslim scholars as "The First Teacher", and among medieval Christians like Thomas Aquinas as simply "The Philosopher", while the poet Dante called him "the master of those who know". His works contain the earliest known formal study of logic, and were studied by medieval scholars such as Peter Abelard and Jean Buridan. Aristotle's influence on logic continued well into the 19th century. In addition, his ethics, although always influential, gained renewed interest with the modern advent of virtue ethics. Life In general, the details of Aristotle's life are not well-established. The biographies written in ancient times are often speculative and historians only agree on a few salient points.[B] Aristotle was born in 384 BC[C] in Stagira, Chalcidice,[2] about 55 km (34 miles) east of modern-day Thessaloniki.[3][4] His father, Nicomachus, was the personal physician to King Amyntas of Macedon. While he was young, Aristotle learned about biology and medical information, which was taught by his father.[5] Both of Aristotle's parents died when he was about thirteen, and Proxenus of Atarneus became his guardian.[6] Although little information about Aristotle's childhood has survived, he probably spent some time within the Macedonian palace, making his first connections with the Macedonian monarchy.[7] School of Aristotle in Mieza, Macedonia, Greece. At the age of seventeen or eighteen, Aristotle moved to Athens to continue his education at Plato's Academy.[8] He probably experienced the Eleusinian Mysteries as he wrote when describing the sights one viewed at the Eleusinian Mysteries, "to experience is to learn" [παθείν μαθεĩν].[9] Aristotle remained in Athens for nearly twenty years before leaving in 348/47 BC. The traditional story about his departure records that he was disappointed with the Academy's direction after control passed to Plato's nephew Speusippus, although it is possible that he feared the anti-Macedonian sentiments in Athens at that time and left before Plato died.[10] Aristotle then accompanied Xenocrates to the court of his friend Hermias of Atarneus in Asia Minor. After the death of Hermias, Aristotle travelled with his pupil Theophrastus to the island of Lesbos, where together they researched the botany and zoology of the island and its sheltered lagoon. While in Lesbos, Aristotle married Pythias, either Hermias's adoptive daughter or niece. They had a daughter, whom they also named Pythias. In 343 BC, Aristotle was invited by Philip II of Macedon to become the tutor to his son Alexander.[11][12] "Aristotle tutoring Alexander" by Jean Leon Gerome Ferris. Aristotle was appointed as the head of the royal Academy of Macedon. During Aristotle's time in the Macedonian court, he gave lessons not only to Alexander but also to two other future kings: Ptolemy and Cassander.[13] Aristotle encouraged Alexander toward eastern conquest, and Aristotle's own attitude towards Persia was unabashedly ethnocentric. In one famous example, he counsels Alexander to be "a leader to the Greeks and a despot to the barbarians, to look after the former as after friends and relatives, and to deal with the latter as with beasts or plants".[13] By 335 BC, Aristotle had returned to Athens, establishing his own school there known as the Lyceum. Aristotle conducted courses at the school for the next twelve years. While in Athens, his wife Pythias died and Aristotle became involved with Herpyllis of Stagira. They had a son whom Aristotle named after his father, Nicomachus. If the Suda – an uncritical compilation from the Middle Ages – is accurate, he may also have had an erômenos, Palaephatus of Abydus.[14] Portrait bust of Aristotle; an Imperial Roman (1st or 2nd century AD) copy of a lost bronze sculpture made by Lysippos. This period in Athens, between 335 and 323 BC, is when Aristotle is believed to have composed many of his works.[12] He wrote many dialogues, of which only fragments have survived. Those works that have survived are in treatise form and were not, for the most part, intended for widespread publication; they are generally thought to be lecture aids for his students. His most important treatises include Physics, Metaphysics, Nicomachean Ethics, Politics, On the Soul and Poetics. Aristotle studied and made significant contributions to "logic, metaphysics, mathematics, physics, biology, botany, ethics, politics, agriculture, medicine, dance, and theatre."[15] Near the end of his life, Alexander and Aristotle became estranged over Alexander's relationship with Persia and Persians. A widespread tradition in antiquity suspected Aristotle of playing a role in Alexander's death, but the only evidence of this is an unlikely claim made some six years after the death.[16] Following Alexander's death, anti-Macedonian sentiment in Athens was rekindled. In 322 BC, Demophilus and Eurymedon the Hierophant reportedly denounced Aristotle for impiety,[17] prompting him to flee to his mother's family estate in Chalcis, on Euboea, at which occasion he was said to have stated: "I will not allow the Athenians to sin twice against philosophy"[18][19][20] – a reference to Athens's trial and execution of Socrates. He died in Chalcis, Euboea[2][21][15] of natural causes later that same year, having named his student Antipater as his chief executor and leaving a will in which he asked to be buried next to his wife.[22] Theoretical philosophy Logic Main article: Term logic Further information: Non-Aristotelian logic With the Prior Analytics, Aristotle is credited with the earliest study of formal logic,[23] and his conception of it was the dominant form of Western logic until 19th-century advances in mathematical logic.[24] Kant stated in the Critique of Pure Reason that with Aristotle, logic reached its completion.[25] Organon Main article: Organon Plato (left) and Aristotle in Raphael's 1509 fresco, The School of Athens. Aristotle holds his Nicomachean Ethics and gestures to the earth, representing his view in immanent realism, whilst Plato gestures to the heavens, indicating his Theory of Forms, and holds his Timaeus.[26][27] Most of Aristotle's work is probably not in its original form, because it was most likely edited by students and later lecturers. The logical works of Aristotle were compiled into a set of six books called the Organon around 40 BC by Andronicus of Rhodes or others among his followers.[28] The books are: Categories On Interpretation Prior Analytics Posterior Analytics Topics On Sophistical Refutations The order of the books (or the teachings from which they are composed) is not certain, but this list was derived from analysis of Aristotle's writings. It goes from the basics, the analysis of simple terms in the Categories, the analysis of propositions and their elementary relations in On Interpretation, to the study of more complex forms, namely, syllogisms (in the Analytics)[29][30] and dialectics (in the Topics and Sophistical Refutations). The first three treatises form the core of the logical theory stricto sensu: the grammar of the language of logic and the correct rules of reasoning. The Rhetoric is not conventionally included, but it states that it relies on the Topics.[31] One of Aristotle's types of syllogism[D] In words In terms[E] In equations[F] All men are mortal. All Greeks are men. ∴ All Greeks are mortal. M a P S a M S a P What is today called Aristotelian logic with its types of syllogism (methods of logical argument),[32] Aristotle himself would have labelled "analytics". The term "logic" he reserved to mean dialectics. Metaphysics Main article: Metaphysics (Aristotle) The word "metaphysics" appears to have been coined by the first century AD editor who assembled various small selections of Aristotle's works to the treatise we know by the name Metaphysics.[34] Aristotle called it "first philosophy", and distinguished it from mathematics and natural science (physics) as the contemplative (theoretikē) philosophy which is "theological" and studies the divine. He wrote in his Metaphysics (1026a16): if there were no other independent things besides the composite natural ones, the study of nature would be the primary kind of knowledge; but if there is some motionless independent thing, the knowledge of this precedes it and is first philosophy, and it is universal in just this way, because it is first. And it belongs to this sort of philosophy to study being as being, both what it is and what belongs to it just by virtue of being.[35] Substance Further information: Hylomorphism Aristotle examines the concepts of substance (ousia) and essence (to ti ên einai, "the what it was to be") in his Metaphysics (Book VII), and he concludes that a particular substance is a combination of both matter and form, a philosophical theory called hylomorphism. In Book VIII, he distinguishes the matter of the substance as the substratum, or the stuff of which it is composed. For example, the matter of a house is the bricks, stones, timbers, etc., or whatever constitutes the potential house, while the form of the substance is the actual house, namely 'covering for bodies and chattels' or any other differentia that let us define something as a house. The formula that gives the components is the account of the matter, and the formula that gives the differentia is the account of the form.[36][34] Immanent realism Main article: Aristotle's theory of universals Plato's forms exist as universals, like the ideal form of an apple. For Aristotle, both matter and form belong to the individual thing (hylomorphism). Like his teacher Plato, Aristotle's philosophy aims at the universal. Aristotle's ontology places the universal (katholou) in particulars (kath' hekaston), things in the world, whereas for Plato the universal is a separately existing form which actual things imitate. For Aristotle, "form" is still what phenomena are based on, but is "instantiated" in a particular substance.[34] Plato argued that all things have a universal form, which could be either a property or a relation to other things. When one looks at an apple, for example, one sees an apple, and one can also analyse a form of an apple. In this distinction, there is a particular apple and a universal form of an apple. Moreover, one can place an apple next to a book, so that one can speak of both the book and apple as being next to each other. Plato argued that there are some universal forms that are not a part of particular things. For example, it is possible that there is no particular good in existence, but "good" is still a proper universal form. Aristotle disagreed with Plato on this point, arguing that all universals are instantiated at some period of time, and that there are no universals that are unattached to existing things. In addition, Aristotle disagreed with Plato about the location of universals. Where Plato spoke of the forms as existing separately from the things that participate in them, Aristotle maintained that universals exist within each thing on which each universal is predicated. So, according to Aristotle, the form of apple exists within each apple, rather than in the world of the forms.[34][37] Potentiality and actuality Concerning the nature of change (kinesis) and its causes, as he outlines in his Physics and On Generation and Corruption (319b–320a), he distinguishes coming-to-be (genesis, also translated as 'generation') from: growth and diminution, which is change in quantity; locomotion, which is change in space; and alteration, which is change in quality. Aristotle argued that a capability like playing the flute could be acquired – the potential made actual – by learning. Coming-to-be is a change where the substrate of the thing that has undergone the change has itself changed. In that particular change he introduces the concept of potentiality (dynamis) and actuality (entelecheia) in association with the matter and the form. Referring to potentiality, this is what a thing is capable of doing or being acted upon if the conditions are right and it is not prevented by something else. For example, the seed of a plant in the soil is potentially (dynamei) a plant, and if it is not prevented by something, it will become a plant. Potentially, beings can either 'act' (poiein) or 'be acted upon' (paschein), which can be either innate or learned. For example, the eyes possess the potentiality of sight (innate – being acted upon), while the capability of playing the flute can be possessed by learning (exercise – acting). Actuality is the fulfilment of the end of the potentiality. Because the end (telos) is the principle of every change, and potentiality exists for the sake of the end, actuality, accordingly, is the end. Referring then to the previous example, it can be said that an actuality is when a plant does one of the activities that plants do.[34] For that for the sake of which (to hou heneka) a thing is, is its principle, and the becoming is for the sake of the end; and the actuality is the end, and it is for the sake of this that the potentiality is acquired. For animals do not see in order that they may have sight, but they have sight that they may see.[38] In summary, the matter used to make a house has potentiality to be a house and both the activity of building and the form of the final house are actualities, which is also a final cause or end. Then Aristotle proceeds and concludes that the actuality is prior to potentiality in formula, in time and in substantiality. With this definition of the particular substance (i.e., matter and form), Aristotle tries to solve the problem of the unity of the beings, for example, "what is it that makes a man one"? Since, according to Plato there are two Ideas: animal and biped, how then is man a unity? However, according to Aristotle, the potential being (matter) and the actual one (form) are one and the same.[34][39] Epistemology Aristotle's immanent realism means his epistemology is based on the study of things that exist or happen in the world, and rises to knowledge of the universal, whereas for Plato epistemology begins with knowledge of universal Forms (or ideas) and descends to knowledge of particular imitations of these.[31] Aristotle uses induction from examples alongside deduction, whereas Plato relies on deduction from a priori principles.[31] Natural philosophy Aristotle's "natural philosophy" spans a wide range of natural phenomena including those now covered by physics, biology and other natural sciences.[40] In Aristotle's terminology, "natural philosophy" is a branch of philosophy examining the phenomena of the natural world, and includes fields that would be regarded today as physics, biology and other natural sciences. Aristotle's work encompassed virtually all facets of intellectual inquiry. Aristotle makes philosophy in the broad sense coextensive with reasoning, which he also would describe as "science". However, his use of the term science carries a different meaning than that covered by the term "scientific method". For Aristotle, "all science (dianoia) is either practical, poetical or theoretical" (Metaphysics 1025b25). His practical science includes ethics and politics; his poetical science means the study of fine arts including poetry; his theoretical science covers physics, mathematics and metaphysics.[40] Physics The four classical elements (fire, air, water, earth) of Empedocles and Aristotle illustrated with a burning log. The log releases all four elements as it is destroyed. Main article: Aristotelian physics Five elements Main article: Classical element In his On Generation and Corruption, Aristotle related each of the four elements proposed earlier by Empedocles, earth, water, air, and fire, to two of the four sensible qualities, hot, cold, wet, and dry. In the Empedoclean scheme, all matter was made of the four elements, in differing proportions. Aristotle's scheme added the heavenly aether, the divine substance of the heavenly spheres, stars and planets.[41] Aristotle's elements[41] Element Hot/Cold Wet/Dry Motion Modern state of matter Earth Cold Dry Down Solid Water Cold Wet Down Liquid Air Hot Wet Up Gas Fire Hot Dry Up Plasma Aether (divine substance) — Circular (in heavens) Vacuum Motion Further information: History of classical mechanics Aristotle describes two kinds of motion: "violent" or "unnatural motion", such as that of a thrown stone, in the Physics (254b10), and "natural motion", such as of a falling object, in On the Heavens (300a20). In violent motion, as soon as the agent stops causing it, the motion stops also: in other words, the natural state of an object is to be at rest,[42][G] since Aristotle does not address friction.[43] With this understanding, it can be observed that, as Aristotle stated, heavy objects (on the ground, say) require more force to make them move; and objects pushed with greater force move faster.[44][H] This would imply the equation[44] 𝐹 = 𝑚 𝑣 {\displaystyle F=mv}, incorrect in modern physics.[44] Natural motion depends on the element concerned: the aether naturally moves in a circle around the heavens,[I] while the 4 Empedoclean elements move vertically up (like fire, as is observed) or down (like earth) towards their natural resting places.[45][43][J] Aristotle's laws of motion. In Physics he states that objects fall at a speed proportional to their weight and inversely proportional to the density of the fluid they are immersed in.[43] This is a correct approximation for objects in Earth's gravitational field moving in air or water.[45] In the Physics (215a25), Aristotle effectively states a quantitative law, that the speed, v, of a falling body is proportional (say, with constant c) to its weight, W, and inversely proportional to the density,[K] ρ, of the fluid in which it is falling:;[45][43] 𝑣 = 𝑐 𝑊 𝜌{\displaystyle v=c{\frac {W}{\rho }}} Aristotle implies that in a vacuum the speed of fall would become infinite, and concludes from this apparent absurdity that a vacuum is not possible.[45][43] Opinions have varied on whether Aristotle intended to state quantitative laws. Henri Carteron held the "extreme view"[43] that Aristotle's concept of force was basically qualitative,[46] but other authors reject this.[43] Archimedes corrected Aristotle's theory that bodies move towards their natural resting places; metal boats can float if they displace enough water; floating depends in Archimedes' scheme on the mass and volume of the object, not, as Aristotle thought, its elementary composition.[45] Aristotle's writings on motion remained influential until the Early Modern period. John Philoponus (in Late antiquity) and Galileo (in Early modern period) are said to have shown by experiment that Aristotle's claim that a heavier object falls faster than a lighter object is incorrect.[40] A contrary opinion is given by Carlo Rovelli, who argues that Aristotle's physics of motion is correct within its domain of validity, that of objects in the Earth's gravitational field immersed in a fluid such as air. In this system, heavy bodies in steady fall indeed travel faster than light ones (whether friction is ignored, or not[45]), and they do fall more slowly in a denser medium.[44][L] Newton's "forced" motion corresponds to Aristotle's "violent" motion with its external agent, but Aristotle's assumption that the agent's effect stops immediately it stops acting (e.g., the ball leaves the thrower's hand) has awkward consequences: he has to suppose that surrounding fluid helps to push the ball along to make it continue to rise even though the hand is no longer acting on it, resulting in the Medieval theory of impetus.[45] Four causes Main article: Four causes Aristotle argued by analogy with woodwork that a thing takes its form from four causes: in the case of a table, the wood used (material cause), its design (formal cause), the tools and techniques used (efficient cause), and its decorative or practical purpose (final cause).[47] Aristotle suggested that the reason for anything coming about can be attributed to four different types of simultaneously active factors. His term aitia is traditionally translated as "cause", but it does not always refer to temporal sequence; it might be better translated as "explanation", but the traditional rendering will be employed here.[48][49] Material cause describes the material out of which something is composed. Thus the material cause of a table is wood. It is not about action. It does not mean that one domino knocks over another domino.[48] The formal cause is its form, i.e., the arrangement of that matter. It tells one what a thing is, that a thing is determined by the definition, form, pattern, essence, whole, synthesis or archetype. It embraces the account of causes in terms of fundamental principles or general laws, as the whole (i.e., macrostructure) is the cause of its parts, a relationship known as the whole-part causation. Plainly put, the formal cause is the idea in the mind of the sculptor that brings the sculpture into being. A simple example of the formal cause is the mental image or idea that allows an artist, architect, or engineer to create a drawing.[48] The efficient cause is "the primary source", or that from which the change under consideration proceeds. It identifies 'what makes of what is made and what causes change of what is changed' and so suggests all sorts of agents, non-living or living, acting as the sources of change or movement or rest. Representing the current understanding of causality as the relation of cause and effect, this covers the modern definitions of "cause" as either the agent or agency or particular events or states of affairs. In the case of two dominoes, when the first is knocked over it causes the second also to fall over.[48] In the case of animals, this agency is a combination of how it develops from the egg, and how its body functions.[50] The final cause (telos) is its purpose, the reason why a thing exists or is done, including both purposeful and instrumental actions and activities. The final cause is the purpose or function that something is supposed to serve. This covers modern ideas of motivating causes, such as volition.[48] In the case of living things, it implies adaptation to a particular way of life.[50] Optics Further information: History of optics Aristotle describes experiments in optics using a camera obscura in Problems, book 15. The apparatus consisted of a dark chamber with a small aperture that let light in. With it, he saw that whatever shape he made the hole, the sun's image always remained circular. He also noted that increasing the distance between the aperture and the image surface magnified the image.[51] Chance and spontaneity Further information: Accident (philosophy) According to Aristotle, spontaneity and chance are causes of some things, distinguishable from other types of cause such as simple necessity. Chance as an incidental cause lies in the realm of accidental things, "from what is spontaneous". There is also more a specific kind of chance, which Aristotle names "luck", that only applies to people's moral choices.[52][53] Astronomy Further information: History of astronomy In astronomy, Aristotle refuted Democritus's claim that the Milky Way was made up of "those stars which are shaded by the earth from the sun's rays," pointing out partly correctly that if "the size of the sun is greater than that of the earth and the distance of the stars from the earth many times greater than that of the sun, then... the sun shines on all the stars and the earth screens none of them."[54] He also wrote descriptions of comets, including the Great Comet of 371 BC.[55] Geology and natural sciences Further information: History of geology Aristotle noted that the ground level of the Aeolian islands changed before a volcanic eruption. Aristotle was one of the first people to record any geological observations. He stated that geological change was too slow to be observed in one person's lifetime.[56][57] The geologist Charles Lyell noted that Aristotle described such change, including "lakes that had dried up" and "deserts that had become watered by rivers", giving as examples the growth of the Nile delta since the time of Homer, and "the upheaving of one of the Aeolian islands, previous to a volcanic eruption."'[58] Meteorologica lends its name to the modern study of meteorology, but its modern usage diverges from the content of Aristotle's ancient treatise on meteors. The ancient Greeks did use the term for a range of atmospheric phenomena, but also for earthquakes and volcanic eruptions. Aristotle proposed that the cause of earthquakes was a gas or vapor (anathymiaseis) that was trapped inside the earth and trying to escape, following other Greek authors Anaxagoras, Empedocles and Democritus.[59] Aristotle also made many observations about the hydrologic cycle. For example, he made some of the earliest observations about desalination: he observed early – and correctly – that when seawater is heated, freshwater evaporates and that the oceans are then replenished by the cycle of rainfall and river runoff ("I have proved by experiment that salt water evaporated forms fresh and the vapor does not when it condenses condense into sea water again.")[60] Biology Main article: Aristotle's biology Among many pioneering zoological observations, Aristotle described the reproductive hectocotyl arm of the octopus (bottom left). Empirical research Aristotle was the first person to study biology systematically,[61] and biology forms a large part of his writings. He spent two years observing and describing the zoology of Lesbos and the surrounding seas, including in particular the Pyrrha lagoon in the centre of Lesbos.[62][63] His data in History of Animals, Generation of Animals, Movement of Animals, and Parts of Animals are assembled from his own observations,[64] statements given by people with specialized knowledge, such as beekeepers and fishermen, and less accurate accounts provided by travellers from overseas.[65] His apparent emphasis on animals rather than plants is a historical accident: his works on botany have been lost, but two books on plants by his pupil Theophrastus have survived.[66] Aristotle reports on the sea-life visible from observation on Lesbos and the catches of fishermen. He describes the catfish, electric ray, and frogfish in detail, as well as cephalopods such as the octopus and paper nautilus. His description of the hectocotyl arm of cephalopods, used in sexual reproduction, was widely disbelieved until the 19th century.[67] He gives accurate descriptions of the four-chambered fore-stomachs of ruminants,[68] and of the ovoviviparous embryological development of the hound shark.[69] He notes that an animal's structure is well matched to function so birds like the heron (which live in marshes with soft mud and live by catching fish) have a long neck, long legs, and a sharp spear-like beak, whereas ducks that swim have short legs and webbed feet.[70] Darwin, too, noted these sorts of differences between similar kinds of animal, but unlike Aristotle used the data to come to the theory of evolution.[71] Aristotle's writings can seem to modern readers close to implying evolution, but while Aristotle was aware that new mutations or hybridizations could occur, he saw these as rare accidents. For Aristotle, accidents, like heat waves in winter, must be considered distinct from natural causes. He was thus critical of Empedocles's materialist theory of a "survival of the fittest" origin of living things and their organs, and ridiculed the idea that accidents could lead to orderly results.[72] To put his views into modern terms, he nowhere says that different species can have a common ancestor, or that one kind can change into another, or that kinds can become extinct.[73] Scientific style Aristotle inferred growth laws from his observations on animals, including that brood size decreases with body mass, whereas gestation period increases. He was correct in these predictions, at least for mammals: data are shown for mouse and elephant. Aristotle did not do experiments in the modern sense.[74] He used the ancient Greek term pepeiramenoi to mean observations, or at most investigative procedures like dissection.[75] In Generation of Animals, he finds a fertilized hen's egg of a suitable stage and opens it to see the embryo's heart beating inside.[76][77] Instead, he practiced a different style of science: systematically gathering data, discovering patterns common to whole groups of animals, and inferring possible causal explanations from these.[78][79] This style is common in modern biology when large amounts of data become available in a new field, such as genomics. It does not result in the same certainty as experimental science, but it sets out testable hypotheses and constructs a narrative explanation of what is observed. In this sense, Aristotle's biology is scientific.[78] From the data he collected and documented, Aristotle inferred quite a number of rules relating the life-history features of the live-bearing tetrapods (terrestrial placental mammals) that he studied. Among these correct predictions are the following. Brood size decreases with (adult) body mass, so that an elephant has fewer young (usually just one) per brood than a mouse. Lifespan increases with gestation period, and also with body mass, so that elephants live longer than mice, have a longer period of gestation, and are heavier. As a final example, fecundity decreases with lifespan, so long-lived kinds like elephants have fewer young in total than short-lived kinds like mice.[80] Classification of living things Further information: Scala naturae Aristotle recorded that the embryo of a dogfish was attached by a cord to a kind of placenta (the yolk sac), like a higher animal; this formed an exception to the linear scale from highest to lowest.[81] Aristotle distinguished about 500 species of animals,[82][83] arranging these in the History of Animals in a graded scale of perfection, a nonreligious version of the scala naturae, with man at the top. His system had eleven grades of animal, from highest potential to lowest, expressed in their form at birth: the highest gave live birth to hot and wet creatures, the lowest laid cold, dry mineral-like eggs. Animals came above plants, and these in turn were above minerals.[84][85] He grouped what the modern zoologist would call vertebrates as the hotter "animals with blood", and below them the colder invertebrates as "animals without blood". Those with blood were divided into the live-bearing (mammals), and the egg-laying (birds, reptiles, fish). Those without blood were insects, crustacea (non-shelled – cephalopods, and shelled) and the hard-shelled molluscs (bivalves and gastropods). He recognised that animals did not exactly fit into a linear scale, and noted various exceptions, such as that sharks had a placenta like the tetrapods. To a modern biologist, the explanation, not available to Aristotle, is convergent evolution.[86] Philosophers of science have generally concluded that Aristotle was not interested in taxonomy,[87][88] but zoologists who studied this question in the early 21st century think otherwise.[89][90][91] He believed that purposive final causes guided all natural processes; this teleological view justified his observed data as an expression of formal design.[92] Aristotle's Scala naturae (highest to lowest) Group Examples (given by Aristotle) Blood Legs Souls (Rational, Sensitive, Vegetative) Qualities (Hot–Cold, Wet–Dry) Man Man with blood 2 legs R, S, V Hot, Wet Live-bearing tetrapods Cat, hare with blood 4 legs S, V Hot, Wet Cetaceans Dolphin, whale with blood none S, V Hot, Wet Birds Bee-eater, nightjar with blood 2 legs S, V Hot, Wet, except Dry eggs Egg-laying tetrapods Chameleon, crocodile with blood 4 legs S, V Cold, Wet except scales, eggs Snakes Water snake, Ottoman viper with blood none S, V Cold, Wet except scales, eggs Egg-laying fishes Sea bass, parrotfish with blood none S, V Cold, Wet, including eggs (Among the egg-laying fishes): placental selachians Shark, skate with blood none S, V Cold, Wet, but placenta like tetrapods Crustaceans Shrimp, crab without many legs S, V Cold, Wet except shell Cephalopods Squid, octopus without tentacles S, V Cold, Wet Hard-shelled animals Cockle, trumpet snail without none S, V Cold, Dry (mineral shell) Larva-bearing insects Ant, cicada without 6 legs S, V Cold, Dry Spontaneously generating Sponges, worms without none S, V Cold, Wet or Dry, from earth Plants Fig without none V Cold, Dry Minerals Iron without none none Cold, Dry Psychology Soul Further information: On the Soul Aristotle proposed a three-part structure for souls of plants, animals, and humans, making humans unique in having all three types of soul. Aristotle's psychology, given in his treatise On the Soul (peri psychēs), posits three kinds of soul ("psyches"): the vegetative soul, the sensitive soul, and the rational soul. Humans have all three. The vegetative soul is concerned with growth and nourishment. The sensitive soul experiences sensations and movement. The unique part of the human, rational soul is its ability to receive forms of other things and to compare them using the nous (intellect) and logos (reason).[93] For Aristotle, the soul is the form of a living being. Because all beings are composites of form and matter, the form of living beings is that which endows them with what is specific to living beings, e.g. the ability to initiate movement (or in the case of plants, growth and transformations, which Aristotle considers types of movement).[11] In contrast to earlier philosophers, but in accordance with the Egyptians, he placed the rational soul in the heart, rather than the brain.[94] Notable is Aristotle's division of sensation and thought, which generally differed from the concepts of previous philosophers, with the exception of Alcmaeon.[95] In On the Soul, Aristotle famously criticizes Plato's theory of the soul and develops his own in response. The first criticism is against Plato's view of the soul in the Timaeus that the soul takes up space and is able to come into physical contact with bodies.[96] 20th-century scholarship overwhelmingly opposed Aristotle's interpretation of Plato and maintained that he had misunderstood him.[97] Today's scholars have tended to re-assess Aristotle's interpretation and been more positive about it.[98] Aristotle's other criticism is that Plato's view of reincarnation entails that it is possible for a soul and its body to be mis-matched; in principle, Aristotle alleges, any soul can go with any body, according to Plato's theory.[99] Aristotle's claim that the soul is the form of a living being eliminates that possibility and thus rules out reincarnation.[100] Memory According to Aristotle in On the Soul, memory is the ability to hold a perceived experience in the mind and to distinguish between the internal "appearance" and an occurrence in the past.[101] In other words, a memory is a mental picture (phantasm) that can be recovered. Aristotle believed an impression is left on a semi-fluid bodily organ that undergoes several changes in order to make a memory. A memory occurs when stimuli such as sights or sounds are so complex that the nervous system cannot receive all the impressions at once. These changes are the same as those involved in the operations of sensation, Aristotelian 'common sense', and thinking.[102][103] Aristotle uses the term 'memory' for the actual retaining of an experience in the impression that can develop from sensation, and for the intellectual anxiety that comes with the impression because it is formed at a particular time and processing specific contents. Memory is of the past, prediction is of the future, and sensation is of the present. Retrieval of impressions cannot be performed suddenly. A transitional channel is needed and located in past experiences, both for previous experience and present experience.[104] Because Aristotle believes people receive all kinds of sense perceptions and perceive them as impressions, people are continually weaving together new impressions of experiences. To search for these impressions, people search the memory itself.[105] Within the memory, if one experience is offered instead of a specific memory, that person will reject this experience until they find what they are looking for. Recollection occurs when one retrieved experience naturally follows another. If the chain of "images" is needed, one memory will stimulate the next. When people recall experiences, they stimulate certain previous experiences until they reach the one that is needed.[106] Recollection is thus the self-directed activity of retrieving the information stored in a memory impression.[107] Only humans can remember impressions of intellectual activity, such as numbers and words. Animals that have perception of time can retrieve memories of their past observations. Remembering involves only perception of the things remembered and of the time passed.[108] Senses, perception, memory, dreams, action in Aristotle's psychology. Impressions are stored in the sensorium (the heart), linked by his laws of association (similarity, contrast, and contiguity). Aristotle believed the chain of thought, which ends in recollection of certain impressions, was connected systematically in relationships such as similarity, contrast, and contiguity, described in his laws of association. Aristotle believed that past experiences are hidden within the mind. A force operates to awaken the hidden material to bring up the actual experience. According to Aristotle, association is the power innate in a mental state, which operates upon the unexpressed remains of former experiences, allowing them to rise and be recalled.[109][110] Dreams Further information: Dream § Other Aristotle describes sleep in On Sleep and Wakefulness.[111] Sleep takes place as a result of overuse of the senses[112] or of digestion,[113] so it is vital to the body.[112] While a person is asleep, the critical activities, which include thinking, sensing, recalling and remembering, do not function as they do during wakefulness. Since a person cannot sense during sleep, they cannot have desire, which is the result of sensation. However, the senses are able to work during sleep,[114] albeit differently,[111] unless they are weary.[112] Dreams do not involve actually sensing a stimulus. In dreams, sensation is still involved, but in an altered manner.[112] Aristotle explains that when a person stares at a moving stimulus such as the waves in a body of water, and then looks away, the next thing they look at appears to have a wavelike motion. When a person perceives a stimulus and the stimulus is no longer the focus of their attention, it leaves an impression.[111] When the body is awake and the senses are functioning properly, a person constantly encounters new stimuli to sense and so the impressions of previously perceived stimuli are ignored.[112] However, during sleep the impressions made throughout the day are noticed as there are no new distracting sensory experiences.[111] So, dreams result from these lasting impressions. Since impressions are all that are left and not the exact stimuli, dreams do not resemble the actual waking experience.[115] During sleep, a person is in an altered state of mind. Aristotle compares a sleeping person to a person who is overtaken by strong feelings toward a stimulus. For example, a person who has a strong infatuation with someone may begin to think they see that person everywhere because they are so overtaken by their feelings. Since a person sleeping is in a suggestible state and unable to make judgements, they become easily deceived by what appears in their dreams, like the infatuated person.[111] This leads the person to believe the dream is real, even when the dreams are absurd in nature.[111] In De Anima iii 3, Aristotle ascribes the ability to create, to store, and to recall images in the absence of perception to the faculty of imagination, phantasia.[11] One component of Aristotle's theory of dreams disagrees with previously held beliefs. He claimed that dreams are not foretelling and not sent by a divine being. Aristotle reasoned naturalistically that instances in which dreams do resemble future events are simply coincidences.[116] Aristotle claimed that a dream is first established by the fact that the person is asleep when they experience it. If a person had an image appear for a moment after waking up or if they see something in the dark it is not considered a dream because they were awake when it occurred. Secondly, any sensory experience that is perceived while a person is asleep does not qualify as part of a dream. For example, if, while a person is sleeping, a door shuts and in their dream they hear a door is shut, this sensory experience is not part of the dream. Lastly, the images of dreams must be a result of lasting impressions of waking sensory experiences.[115] Practical philosophy Aristotle's practical philosophy covers areas such as ethics, politics, economics, and rhetoric.[40] Virtues and their accompanying vices[15] Too little Virtuous mean Too much Humbleness High-mindedness Vainglory Lack of purpose Right ambition Over-ambition Spiritlessness Good temper Irascibility Rudeness Civility Obsequiousness Cowardice Courage Rashness Insensibility Self-control Intemperance Sarcasm Sincerity Boastfulness Boorishness Wit Buffoonery Shamelessness Modesty Shyness Callousness Just resentment Spitefulness Pettiness Generosity Vulgarity Meanness Liberality Wastefulness Ethics Main article: Aristotelian ethics Aristotle considered ethics to be a practical rather than theoretical study, i.e., one aimed at becoming good and doing good rather than knowing for its own sake. He wrote several treatises on ethics, most notably including the Nicomachean Ethics.[117] Aristotle taught that virtue has to do with the proper function (ergon) of a thing. An eye is only a good eye in so much as it can see, because the proper function of an eye is sight. Aristotle reasoned that humans must have a function specific to humans, and that this function must be an activity of the psuchē (soul) in accordance with reason (logos). Aristotle identified such an optimum activity (the virtuous mean, between the accompanying vices of excess or deficiency[15]) of the soul as the aim of all human deliberate action, eudaimonia, generally translated as "happiness" or sometimes "well-being". To have the potential of ever being happy in this way necessarily requires a good character (ēthikē aretē), often translated as moral or ethical virtue or excellence.[118] Aristotle taught that to achieve a virtuous and potentially happy character requires a first stage of having the fortune to be habituated not deliberately, but by teachers, and experience, leading to a later stage in which one consciously chooses to do the best things. When the best people come to live life this way their practical wisdom (phronesis) and their intellect (nous) can develop with each other towards the highest possible human virtue, the wisdom of an accomplished theoretical or speculative thinker, or in other words, a philosopher.[119] Politics Main article: Politics (Aristotle) In addition to his works on ethics, which address the individual, Aristotle addressed the city in his work titled Politics. Aristotle considered the city to be a natural community. Moreover, he considered the city to be prior in importance to the family, which in turn is prior to the individual, "for the whole must of necessity be prior to the part".[120] He famously stated that "man is by nature a political animal" and argued that humanity's defining factor among others in the animal kingdom is its rationality.[121] Aristotle conceived of politics as being like an organism rather than like a machine, and as a collection of parts none of which can exist without the others. Aristotle's conception of the city is organic, and he is considered one of the first to conceive of the city in this manner.[122] Aristotle's classifications of political constitutions. The common modern understanding of a political community as a modern state is quite different from Aristotle's understanding. Although he was aware of the existence and potential of larger empires, the natural community according to Aristotle was the city (polis) which functions as a political "community" or "partnership" (koinōnia). The aim of the city is not just to avoid injustice or for economic stability, but rather to allow at least some citizens the possibility to live a good life, and to perform beautiful acts: "The political partnership must be regarded, therefore, as being for the sake of noble actions, not for the sake of living together." This is distinguished from modern approaches, beginning with social contract theory, according to which individuals leave the state of nature because of "fear of violent death" or its "inconveniences".[M] In Protrepticus, the character 'Aristotle' states:[123] For we all agree that the most excellent man should rule, i.e., the supreme by nature, and that the law rules and alone is authoritative; but the law is a kind of intelligence, i.e. a discourse based on intelligence. And again, what standard do we have, what criterion of good things, that is more precise than the intelligent man? For all that this man will choose, if the choice is based on his knowledge, are good things and their contraries are bad. And since everybody chooses most of all what conforms to their own proper dispositions (a just man choosing to live justly, a man with bravery to live bravely, likewise a self-controlled man to live with self-control), it is clear that the intelligent man will choose most of all to be intelligent; for this is the function of that capacity. Hence it's evident that, according to the most authoritative judgment, intelligence is supreme among goods.[123] As Plato's disciple Aristotle was rather critical concerning democracy and, following the outline of certain ideas from Plato's Statesman, he developed a coherent theory of integrating various forms of power into a so-called mixed state: It is … constitutional to take … from oligarchy that offices are to be elected, and from democracy that this is not to be on a property-qualification. This then is the mode of the mixture; and the mark of a good mixture of democracy and oligarchy is when it is possible to speak of the same constitution as a democracy and as an oligarchy. — Aristotle. Politics, Book 4, 1294b.10–18 Aristotle's views on women influenced later Western philosophers, who quoted him as an authority until the end of the Middle Ages, but these views have been controversial in modern times. Aristotle's analysis of procreation describes an active, ensouling masculine element bringing life to an inert, passive female element. The biological differences are a result of the fact that the female body is well-suited for reproduction, which changes her body temperature, which in turn makes her, in Aristotle's view, incapable of participating in political life.[124] On this ground, proponents of feminist metaphysics have accused Aristotle of misogyny[125] and sexism.[126] However, Aristotle gave equal weight to women's happiness as he did to men's, and commented in his Rhetoric that the things that lead to happiness need to be in women as well as men.[N] Economics Main article: Politics (Aristotle) Aristotle made substantial contributions to economic thought, especially to thought in the Middle Ages.[128] In Politics, Aristotle addresses the city, property, and trade. His response to criticisms of private property, in Lionel Robbins's view, anticipated later proponents of private property among philosophers and economists, as it related to the overall utility of social arrangements.[128] Aristotle believed that although communal arrangements may seem beneficial to society, and that although private property is often blamed for social strife, such evils in fact come from human nature. In Politics, Aristotle offers one of the earliest accounts of the origin of money.[128] Money came into use because people became dependent on one another, importing what they needed and exporting the surplus. For the sake of convenience, people then agreed to deal in something that is intrinsically useful and easily applicable, such as iron or silver.[129] Aristotle's discussions on retail and interest was a major influence on economic thought in the Middle Ages. He had a low opinion of retail, believing that contrary to using money to procure things one needs in managing the household, retail trade seeks to make a profit. It thus uses goods as a means to an end, rather than as an end unto itself. He believed that retail trade was in this way unnatural. Similarly, Aristotle considered making a profit through interest unnatural, as it makes a gain out of the money itself, and not from its use.[129] Aristotle gave a summary of the function of money that was perhaps remarkably precocious for his time. He wrote that because it is impossible to determine the value of every good through a count of the number of other goods it is worth, the necessity arises of a single universal standard of measurement. Money thus allows for the association of different goods and makes them "commensurable".[129] He goes on to state that money is also useful for future exchange, making it a sort of security. That is, "if we do not want a thing now, we shall be able to get it when we do want it".[129] Rhetoric Part of a series on Rhetoric History Concepts Genres Criticism Rhetoricians Works Subfields Related vte Main article: Rhetoric (Aristotle) Aristotle's Rhetoric proposes that a speaker can use three basic kinds of appeals to persuade his audience: ethos (an appeal to the speaker's character), pathos (an appeal to the audience's emotion), and logos (an appeal to logical reasoning).[130] He also categorizes rhetoric into three genres: epideictic (ceremonial speeches dealing with praise or blame), forensic (judicial speeches over guilt or innocence), and deliberative (speeches calling on an audience to make a decision on an issue).[131] Aristotle also outlines two kinds of rhetorical proofs: enthymeme (proof by syllogism) and paradeigma (proof by example).[132] Poetics Main article: Poetics (Aristotle) Aristotle writes in his Poetics that epic poetry, tragedy, comedy, dithyrambic poetry, painting, sculpture, music, and dance are all fundamentally acts of mimesis ("imitation"), each varying in imitation by medium, object, and manner.[133][134] He applies the term mimesis both as a property of a work of art and also as the product of the artist's intention[133] and contends that the audience's realisation of the mimesis is vital to understanding the work itself.[133] Aristotle states that mimesis is a natural instinct of humanity that separates humans from animals[133][135] and that all human artistry "follows the pattern of nature".[133] Because of this, Aristotle believed that each of the mimetic arts possesses what Stephen Halliwell calls "highly structured procedures for the achievement of their purposes."[136] For example, music imitates with the media of rhythm and harmony, whereas dance imitates with rhythm alone, and poetry with language. The forms also differ in their object of imitation. Comedy, for instance, is a dramatic imitation of men worse than average; whereas tragedy imitates men slightly better than average. Lastly, the forms differ in their manner of imitation – through narrative or character, through change or no change, and through drama or no drama.[137] The Blind Oedipus Commending his Children to the Gods (1784) by Bénigne Gagneraux. In his Poetics, Aristotle uses the tragedy Oedipus Tyrannus by Sophocles as an example of how the perfect tragedy should be structured, with a generally good protagonist who starts the play prosperous, but loses everything through some hamartia (fault).[138] While it is believed that Aristotle's Poetics originally comprised two books – one on comedy and one on tragedy – only the portion that focuses on tragedy has survived. Aristotle taught that tragedy is composed of six elements: plot-structure, character, style, thought, spectacle, and lyric poetry.[139] The characters in a tragedy are merely a means of driving the story; and the plot, not the characters, is the chief focus of tragedy. Tragedy is the imitation of action arousing pity and fear, and is meant to effect the catharsis of those same emotions. Aristotle concludes Poetics with a discussion on which, if either, is superior: epic or tragic mimesis. He suggests that because tragedy possesses all the attributes of an epic, possibly possesses additional attributes such as spectacle and music, is more unified, and achieves the aim of its mimesis in shorter scope, it can be considered superior to epic.[140] Aristotle was a keen systematic collector of riddles, folklore, and proverbs; he and his school had a special interest in the riddles of the Delphic Oracle and studied the fables of Aesop.[141] Transmission Further information: List of writers influenced by Aristotle More than 2300 years after his death, Aristotle remains one of the most influential people who ever lived.[142][143][144] He contributed to almost every field of human knowledge then in existence, and he was the founder of many new fields. According to the philosopher Bryan Magee, "it is doubtful whether any human being has ever known as much as he did".[145] Among countless other achievements, Aristotle was the founder of formal logic,[146] pioneered the study of zoology, and left every future scientist and philosopher in his debt through his contributions to the scientific method.[2][147][148] Taneli Kukkonen, observes that his achievement in founding two sciences is unmatched, and his reach in influencing "every branch of intellectual enterprise" including Western ethical and political theory, theology, rhetoric, and literary analysis is equally long. As a result, Kukkonen argues, any analysis of reality today "will almost certainly carry Aristotelian overtones ... evidence of an exceptionally forceful mind."[148] Jonathan Barnes wrote that "an account of Aristotle's intellectual afterlife would be little less than a history of European thought".[149] Aristotle has been called the father of logic, biology, political science, zoology, embryology, natural law, scientific method, rhetoric, psychology, realism, criticism, individualism, teleology, and meteorology.[151] The scholar Taneli Kukkonen notes that "in the best 20th-century scholarship Aristotle comes alive as a thinker wrestling with the full weight of the Greek philosophical tradition."[148] What follows is an overview of the transmission and influence of his texts and ideas into the modern era. His successor, Theophrastus Main articles: Theophrastus and Historia Plantarum (Theophrastus) Frontispiece to a 1644 version of Theophrastus's Historia Plantarum, originally written around 300 BC. Aristotle's pupil and successor, Theophrastus, wrote the History of Plants, a pioneering work in botany. Some of his technical terms remain in use, such as carpel from carpos, fruit, and pericarp, from pericarpion, seed chamber.[152] Theophrastus was much less concerned with formal causes than Aristotle was, instead pragmatically describing how plants functioned.[153][154] Later Greek philosophy Further information: Peripatetic school The immediate influence of Aristotle's work was felt as the Lyceum grew into the Peripatetic school. Aristotle's students included Aristoxenus, Dicaearchus, Demetrius of Phalerum, Eudemos of Rhodes, Harpalus, Hephaestion, Mnason of Phocis, Nicomachus, and Theophrastus. Aristotle's influence over Alexander the Great is seen in the latter's bringing with him on his expedition a host of zoologists, botanists, and researchers. He had also learned a great deal about Persian customs and traditions from his teacher. Although his respect for Aristotle was diminished as his travels made it clear that much of Aristotle's geography was clearly wrong, when the old philosopher released his works to the public, Alexander complained "Thou hast not done well to publish thy acroamatic doctrines; for in what shall I surpass other men if those doctrines wherein I have been trained are to be all men's common property?"[155] Hellenistic science Further information: Ancient Greek medicine After Theophrastus, the Lyceum failed to produce any original work. Though interest in Aristotle's ideas survived, they were generally taken unquestioningly.[156] It is not until the age of Alexandria under the Ptolemies that advances in biology can be again found. The first medical teacher at Alexandria, Herophilus of Chalcedon, corrected Aristotle, placing intelligence in the brain, and connected the nervous system to motion and sensation. Herophilus also distinguished between veins and arteries, noting that the latter pulse while the former do not.[157] Though a few ancient atomists such as Lucretius challenged the teleological viewpoint of Aristotelian ideas about life, teleology (and after the rise of Christianity, natural theology) would remain central to biological thought essentially until the 18th and 19th centuries. Ernst Mayr states that there was "nothing of any real consequence in biology after Lucretius and Galen until the Renaissance."[158] Revival In the slumbering centuries following the decline of the Roman Empire, Aristotle's vast philosophical and scientific corpus lay largely dormant in the West. But in the burgeoning intellectual heartland of the Abbasid Caliphate, his works underwent a remarkable revival.[159] Translated into Arabic alongside other Greek classics, Aristotle's logic, ethics, and natural philosophy ignited the minds of early Islamic scholars.[160] Through meticulous commentaries and critical engagements, figures like Al-Farabi and Ibn Sina (Avicenna) breathed new life into Aristotle's ideas. They harmonized his logic with Islamic theology, employed his scientific methodologies to explore the natural world, and even reinterpreted his ethics within the framework of Islamic morality. This revival was not mere imitation. Islamic thinkers embraced Aristotle's rigorous methods while simultaneously challenging his conclusions where they diverged from their own religious beliefs.[161] Byzantine scholars See also: Commentaries on Aristotle and Byzantine Aristotelianism Greek Christian scribes played a crucial role in the preservation of Aristotle by copying all the extant Greek language manuscripts of the corpus. The first Greek Christians to comment extensively on Aristotle were Philoponus, Elias, and David in the sixth century, and Stephen of Alexandria in the early seventh century.[162] John Philoponus stands out for having attempted a fundamental critique of Aristotle's views on the eternity of the world, movement, and other elements of Aristotelian thought.[163] Philoponus questioned Aristotle's teaching of physics, noting its flaws and introducing the theory of impetus to explain his observations.[164] After a hiatus of several centuries, formal commentary by Eustratius and Michael of Ephesus reappeared in the late eleventh and early twelfth centuries, apparently sponsored by Anna Comnena.[165] Medieval Islamic world Further information: Logic in Islamic philosophy and Transmission of the Greek Classics Islamic portrayal of Aristotle (right) in the Kitāb naʿt al-ḥayawān, c. 1220.[166] Aristotle was one of the most revered Western thinkers in early Islamic theology. Most of the still extant works of Aristotle,[167] as well as a number of the original Greek commentaries, were translated into Arabic and studied by Muslim philosophers, scientists and scholars. Averroes, Avicenna and Alpharabius, who wrote on Aristotle in great depth, also influenced Thomas Aquinas and other Western Christian scholastic philosophers. Alkindus greatly admired Aristotle's philosophy,[168] and Averroes spoke of Aristotle as the "exemplar" for all future philosophers.[169] Medieval Muslim scholars regularly described Aristotle as the "First Teacher".[167] The title was later used by Western philosophers (as in the famous poem of Dante) who were influenced by the tradition of Islamic philosophy.[170] Medieval Europe Further information: Aristotelianism and Syllogism § Medieval With the loss of the study of ancient Greek in the early medieval Latin West, Aristotle was practically unknown there from c. CE 600 to c. 1100 except through the Latin translation of the Organon made by Boethius. In the twelfth and thirteenth centuries, interest in Aristotle revived and Latin Christians had translations made, both from Arabic translations, such as those by Gerard of Cremona,[171] and from the original Greek, such as those by James of Venice and William of Moerbeke. After the Scholastic Thomas Aquinas wrote his Summa Theologica, working from Moerbeke's translations and calling Aristotle "The Philosopher",[172] the demand for Aristotle's writings grew, and the Greek manuscripts returned to the West, stimulating a revival of Aristotelianism in Europe that continued into the Renaissance.[173] These thinkers blended Aristotelian philosophy with Christianity, bringing the thought of Ancient Greece into the Middle Ages. Scholars such as Boethius, Peter Abelard, and John Buridan worked on Aristotelian logic.[174] According to scholar Roger Theodore Lafferty, Dante built up the philosophy of the Comedy with the works of Aristotle as a foundation, just as the scholastics used Aristotle as the basis for their thinking. Dante knew Aristotle directly from Latin translations of his works and indirectly through quotations in the works of Albert Magnus.[175] Dante even acknowledges Aristotle's influence explicitly in the poem, specifically when Virgil justifies the Inferno's structure by citing the Nicomachean Ethics.[176] Dante famously refers to him as "he / Who is acknowledged Master of those who know".[177][178] Medieval Judaism Moses Maimonides (considered to be the foremost intellectual figure of medieval Judaism)[179] adopted Aristotelianism from the Islamic scholars and based his Guide for the Perplexed on it and that became the basis of Jewish scholastic philosophy. Maimonides also considered Aristotle to be the greatest philosopher that ever lived, and styled him as the "chief of the philosophers".[180][181][182] Also, in his letter to Samuel ibn Tibbon, Maimonides observes that there is no need for Samuel to study the writings of philosophers who preceded Aristotle because the works of the latter are "sufficient by themselves and [superior] to all that were written before them. His intellect, Aristotle's is the extreme limit of human intellect, apart from him upon whom the divine emanation has flowed forth to such an extent that they reach the level of prophecy, there being no level higher".[183] Early Modern science William Harvey's De Motu Cordis, 1628, showed that the blood circulated, contrary to classical era thinking. In the Early Modern period, scientists such as William Harvey in England and Galileo Galilei in Italy reacted against the theories of Aristotle and other classical era thinkers like Galen, establishing new theories based to some degree on observation and experiment. Harvey demonstrated the circulation of the blood, establishing that the heart functioned as a pump rather than being the seat of the soul and the controller of the body's heat, as Aristotle thought.[184] Galileo used more doubtful arguments to displace Aristotle's physics, proposing that bodies all fall at the same speed whatever their weight.[185] 18th and 19th-century science The English mathematician George Boole fully accepted Aristotle's logic, but decided "to go under, over, and beyond" it with his system of algebraic logic in his 1854 book The Laws of Thought. This gives logic a mathematical foundation with equations, enables it to solve equations as well as check validity, and allows it to handle a wider class of problems by expanding propositions of any number of terms, not just two.[186] Charles Darwin regarded Aristotle as the most important contributor to the subject of biology. In an 1882 letter he wrote that "Linnaeus and Cuvier have been my two gods, though in very different ways, but they were mere schoolboys to old Aristotle".[187][188] Also, in later editions of the book "On the Origin of Species', Darwin traced evolutionary ideas as far back as Aristotle;[189] the text he cites is a summary by Aristotle of the ideas of the earlier Greek philosopher Empedocles.[190] Present science The philosopher Bertrand Russell claims that "almost every serious intellectual advance has had to begin with an attack on some Aristotelian doctrine". Russell calls Aristotle's ethics "repulsive", and labelled his logic "as definitely antiquated as Ptolemaic astronomy". Russell states that these errors make it difficult to do historical justice to Aristotle, until one remembers what an advance he made upon all of his predecessors.[191] The Dutch historian of science Eduard Jan Dijksterhuis writes that Aristotle and his predecessors showed the difficulty of science by "proceed[ing] so readily to frame a theory of such a general character" on limited evidence from their senses.[192] In 1985, the biologist Peter Medawar could still state in "pure seventeenth century"[193] tones that Aristotle had assembled "a strange and generally speaking rather tiresome farrago of hearsay, imperfect observation, wishful thinking and credulity amounting to downright gullibility".[193][194] Zoologists have frequently mocked Aristotle for errors and unverified secondhand reports. However, modern observation has confirmed several of his more surprising claims.[195][196][197] Aristotle's work remains largely unknown to modern scientists, though zoologists sometimes mention him as the father of biology[150] or in particular of marine biology.[198] Practising zoologists are unlikely to adhere to Aristotle's chain of being, but its influence is still perceptible in the use of the terms "lower" and "upper" to designate taxa such as groups of plants.[199] The evolutionary biologist Armand Marie Leroi has reconstructed Aristotle's biology,[200] while Niko Tinbergen's four questions, based on Aristotle's four causes, are used to analyse animal behaviour; they examine function, phylogeny, mechanism, and ontogeny.[201][202] The concept of homology began with Aristotle;[203] the evolutionary developmental biologist Lewis I. Held commented that he would be interested in the concept of deep homology.[204] Surviving works Corpus Aristotelicum Main article: Works of Aristotle First page of a 1566 edition of the Nicomachean Ethics in Greek and Latin. The works of Aristotle that have survived from antiquity through medieval manuscript transmission are collected in the Corpus Aristotelicum. These texts, as opposed to Aristotle's lost works, are technical philosophical treatises from within Aristotle's school.[205] Reference to them is made according to the organization of Immanuel Bekker's Royal Prussian Academy edition (Aristotelis Opera edidit Academia Regia Borussica, Berlin, 1831–1870), which in turn is based on ancient classifications of these works.[206] Loss and preservation Further information: Transmission of the Greek Classics Aristotle wrote his works on papyrus scrolls, the common writing medium of that era.[O] His writings are divisible into two groups: the "exoteric", intended for the public, and the "esoteric", for use within the Lyceum school.[208][P][209] Aristotle's "lost" works stray considerably in characterization from the surviving Aristotelian corpus. Whereas the lost works appear to have been originally written with a view to subsequent publication, the surviving works mostly resemble lecture notes not intended for publication.[210][208] Cicero's description of Aristotle's literary style as "a river of gold" must have applied to the published works, not the surviving notes.[Q] A major question in the history of Aristotle's works is how the exoteric writings were all lost, and how the ones now possessed came to be found.[212] The consensus is that Andronicus of Rhodes collected the esoteric works of Aristotle's school which existed in the form of smaller, separate works, distinguished them from those of Theophrastus and other Peripatetics, edited them, and finally compiled them into the more cohesive, larger works as they are known today.[213][214] According to Strabo and Plutarch, after Aristotle's death, his library and writings went to Theophrastus (Aristotle's successor as head of the Lycaeum and the Peripatetic school).[215] After the death of Theophrastus, the peripatetic library went to Neleus of Scepsis.[216]: 5  Some time later, the Kingdom of Pergamon began conscripting books for a royal library, and the heirs of Neleus hid their collection in a cellar to prevent it from being seized for that purpose. The library was stored there for about a century and a half, in conditions that were not ideal for document preservation. On the death of Attalus III, which also ended the royal library ambitions, the existence of Aristotelian library was disclosed, and it was purchased by Apellicon and returned to Athens in about 100 BC.[216]: 5–6  Apellicon sought to recover the texts, many of which were seriously degraded at this point due to the conditions in which they were stored. He had them copied out into new manuscripts, and used his best guesswork to fill in the gaps where the originals were unreadable.[216]: 5–6  When Sulla seized Athens in 86 BC, he seized the library and transferred it to Rome. There, Andronicus of Rhodes organized the texts into the first complete edition of Aristotle's works (and works attributed to him).[217] The Aristotelian texts we have today are based on these.[216]: 6–8  Depictions in art Paintings Aristotle has been depicted by major artists including Lucas Cranach the Elder,[218] Justus van Gent, Raphael, Paolo Veronese, Jusepe de Ribera,[219] Rembrandt,[220] and Francesco Hayez over the centuries. Among the best-known depictions is Raphael's fresco The School of Athens, in the Vatican's Apostolic Palace, where the figures of Plato and Aristotle are central to the image, at the architectural vanishing point, reflecting their importance.[221] Rembrandt's Aristotle with a Bust of Homer, too, is a celebrated work, showing the knowing philosopher and the blind Homer from an earlier age: as the art critic Jonathan Jones writes, "this painting will remain one of the greatest and most mysterious in the world, ensnaring us in its musty, glowing, pitch-black, terrible knowledge of time."[222][223] ================================================ FILE: py/core/examples/data/aristotle_v2.txt ================================================ Aristotle[A] (Greek: Ἀριστοτέλης Aristotélēs, pronounced [aristotélɛːs]; 384–322 BC) was an Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science. Little is known about Aristotle's life. He was born in the city of Stagira in northern Greece during the Classical period. His father, Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At 17 or 18, he joined Plato's Academy in Athens and remained there until the age of 37 (c. 347 BC). Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored his son Alexander the Great beginning in 343 BC. He established a library in the Lyceum, which helped him to produce many of his hundreds of books on papyrus scrolls. Though Aristotle wrote many elegant treatises and dialogues for publication, only around a third of his original output has survived, none of it intended for publication. Aristotle provided a complex synthesis of the various philosophies existing prior to him. His teachings and methods of inquiry have had a significant impact across the world, and remain a subject of contemporary philosophical discussion. Aristotle's views profoundly shaped medieval scholarship. The influence of his physical science extended from late antiquity and the Early Middle Ages into the Renaissance, and was not replaced systematically until the Enlightenment and theories such as classical mechanics were developed. He influenced Judeo-Islamic philosophies during the Middle Ages, as well as Christian theology, especially the Neoplatonism of the Early Church and the scholastic tradition of the Catholic Church. Aristotle was revered among medieval Muslim scholars as "The First Teacher", and among medieval Christians like Thomas Aquinas as simply "The Philosopher", while the poet Dante called him "the master of those who know". His works contain the earliest known formal study of logic, and were studied by medieval scholars such as Peter Abelard and Jean Buridan. Aristotle's influence on logic continued well into the 19th century. In addition, his ethics, although always influential, gained renewed interest with the modern advent of virtue ethics. ================================================ FILE: py/core/examples/data/aristotle_v3.txt ================================================ Aristotle proposed a three-part structure for souls of plants, animals, and humans, making humans unique in having all three types of soul. Aristotle's psychology, given in his treatise On the Soul (peri psychēs), posits three kinds of soul ("psyches"): the vegetative soul, the sensitive soul, and the rational soul. Humans have all three. The vegetative soul is concerned with growth and nourishment. The sensitive soul experiences sensations and movement. The unique part of the human, rational soul is its ability to receive forms of other things and to compare them using the nous (intellect) and logos (reason).[93] For Aristotle, the soul is the form of a living being. Because all beings are composites of form and matter, the form of living beings is that which endows them with what is specific to living beings, e.g. the ability to initiate movement (or in the case of plants, growth and transformations, which Aristotle considers types of movement).[11] In contrast to earlier philosophers, but in accordance with the Egyptians, he placed the rational soul in the heart, rather than the brain.[94] Notable is Aristotle's division of sensation and thought, which generally differed from the concepts of previous philosophers, with the exception of Alcmaeon.[95] In On the Soul, Aristotle famously criticizes Plato's theory of the soul and develops his own in response. The first criticism is against Plato's view of the soul in the Timaeus that the soul takes up space and is able to come into physical contact with bodies.[96] 20th-century scholarship overwhelmingly opposed Aristotle's interpretation of Plato and maintained that he had misunderstood him.[97] Today's scholars have tended to re-assess Aristotle's interpretation and been more positive about it.[98] Aristotle's other criticism is that Plato's view of reincarnation entails that it is possible for a soul and its body to be mis-matched; in principle, Aristotle alleges, any soul can go with any body, according to Plato's theory.[99] Aristotle's claim that the soul is the form of a living being eliminates that possibility and thus rules out reincarnation.[100] Memory According to Aristotle in On the Soul, memory is the ability to hold a perceived experience in the mind and to distinguish between the internal "appearance" and an occurrence in the past.[101] In other words, a memory is a mental picture (phantasm) that can be recovered. Aristotle believed an impression is left on a semi-fluid bodily organ that undergoes several changes in order to make a memory. A memory occurs when stimuli such as sights or sounds are so complex that the nervous system cannot receive all the impressions at once. These changes are the same as those involved in the operations of sensation, Aristotelian 'common sense', and thinking.[102][103] Aristotle uses the term 'memory' for the actual retaining of an experience in the impression that can develop from sensation, and for the intellectual anxiety that comes with the impression because it is formed at a particular time and processing specific contents. Memory is of the past, prediction is of the future, and sensation is of the present. Retrieval of impressions cannot be performed suddenly. A transitional channel is needed and located in past experiences, both for previous experience and present experience.[104] Because Aristotle believes people receive all kinds of sense perceptions and perceive them as impressions, people are continually weaving together new impressions of experiences. To search for these impressions, people search the memory itself.[105] Within the memory, if one experience is offered instead of a specific memory, that person will reject this experience until they find what they are looking for. Recollection occurs when one retrieved experience naturally follows another. If the chain of "images" is needed, one memory will stimulate the next. When people recall experiences, they stimulate certain previous experiences until they reach the one that is needed.[106] Recollection is thus the self-directed activity of retrieving the information stored in a memory impression.[107] Only humans can remember impressions of intellectual activity, such as numbers and words. Animals that have perception of time can retrieve memories of their past observations. Remembering involves only perception of the things remembered and of the time passed.[108] Senses, perception, memory, dreams, action in Aristotle's psychology. Impressions are stored in the sensorium (the heart), linked by his laws of association (similarity, contrast, and contiguity). Aristotle believed the chain of thought, which ends in recollection of certain impressions, was connected systematically in relationships such as similarity, contrast, and contiguity, described in his laws of association. Aristotle believed that past experiences are hidden within the mind. A force operates to awaken the hidden material to bring up the actual experience. According to Aristotle, association is the power innate in a mental state, which operates upon the unexpressed remains of former experiences, allowing them to rise and be recalled.[109][110] Dreams Further information: Dream § Other Aristotle describes sleep in On Sleep and Wakefulness.[111] Sleep takes place as a result of overuse of the senses[112] or of digestion,[113] so it is vital to the body.[112] While a person is asleep, the critical activities, which include thinking, sensing, recalling and remembering, do not function as they do during wakefulness. Since a person cannot sense during sleep, they cannot have desire, which is the result of sensation. However, the senses are able to work during sleep,[114] albeit differently,[111] unless they are weary.[112] Dreams do not involve actually sensing a stimulus. In dreams, sensation is still involved, but in an altered manner.[112] Aristotle explains that when a person stares at a moving stimulus such as the waves in a body of water, and then looks away, the next thing they look at appears to have a wavelike motion. When a person perceives a stimulus and the stimulus is no longer the focus of their attention, it leaves an impression.[111] When the body is awake and the senses are functioning properly, a person constantly encounters new stimuli to sense and so the impressions of previously perceived stimuli are ignored.[112] However, during sleep the impressions made throughout the day are noticed as there are no new distracting sensory experiences.[111] So, dreams result from these lasting impressions. Since impressions are all that are left and not the exact stimuli, dreams do not resemble the actual waking experience.[115] During sleep, a person is in an altered state of mind. Aristotle compares a sleeping person to a person who is overtaken by strong feelings toward a stimulus. For example, a person who has a strong infatuation with someone may begin to think they see that person everywhere because they are so overtaken by their feelings. Since a person sleeping is in a suggestible state and unable to make judgements, they become easily deceived by what appears in their dreams, like the infatuated person.[111] This leads the person to believe the dream is real, even when the dreams are absurd in nature.[111] In De Anima iii 3, Aristotle ascribes the ability to create, to store, and to recall images in the absence of perception to the faculty of imagination, phantasia.[11] One component of Aristotle's theory of dreams disagrees with previously held beliefs. He claimed that dreams are not foretelling and not sent by a divine being. Aristotle reasoned naturalistically that instances in which dreams do resemble future events are simply coincidences.[116] Aristotle claimed that a dream is first established by the fact that the person is asleep when they experience it. If a person had an image appear for a moment after waking up or if they see something in the dark it is not considered a dream because they were awake when it occurred. Secondly, any sensory experience that is perceived while a person is asleep does not qualify as part of a dream. For example, if, while a person is sleeping, a door shuts and in their dream they hear a door is shut, this sensory experience is not part of the dream. Lastly, the images of dreams must be a result of lasting impressions of waking sensory experiences.[115] Practical philosophy Aristotle's practical philosophy covers areas such as ethics, politics, economics, and rhetoric.[40] ================================================ FILE: py/core/examples/data/got.txt ================================================ Eddard (Ned) Stark The Lord of Winterfell and new Hand of the King. A devoted father and dutiful lord, he is best characterized by his strong sense of honor, and he strives to always do what is right, regardless of his personal feelings. Catelyn (Cat) Tully Ned’s wife and Lady Stark of Winterfell. She is intelligent, strong, and fiercely devoted to her family, leading her to seek out the person responsible for trying to kill her son Bran. Daenerys Stormborn Targaryen The Dothraki khaleesi (queen) and Targaryen princess. She and her brother are the only surviving members of the Targaryen family, and she grows from a frightened girl to a confident ruler, while still maintaining her kindness, over the course of the novel. Jon Snow Ned Stark’s bastard son. Since Catelyn is not his mother, he is not a proper member of the Stark family, and he often feels himself an outsider. He is also a highly capable swordsman and thinker, with a knack for piercing observations. Tyrion (The Imp) Lannister A small man with a giant intellect and sharp tongue. Tyrion does not pity himself but rather accepts his shortcomings as a little person and turns them to his advantage. He loves his family but recognizes their greed and ambition. Bran Stark One of the youngest of the Stark children. Bran is fascinated by stories of knights and adventure, but when is paralyzed in a fall and realizes he is no longer able to become a knight, he is forced to reconsider his life. Sansa Stark The elder Stark daughter and a beautiful, but extremely naïve, young girl. The twelve-year-old Sansa imagines her life as though it were a storybook, ignoring cruel realities around her and concerning herself only with marrying Joffrey Baratheon. Arya Stark The youngest Stark girl and a wild, willful, but very intelligent child. What the ten-year-old Ayra lacks in her sister’s refinement, she makes up for with skill in swordfighting and riding. Arya rejects the idea of a woman’s role being to marry and have babies. Cersei Lannister Queen of the realm and wife of Robert Baratheon. She despises Robert (as well as most other people it seems), and she is cunning and extremely ambitious. Ser Jaime (The Kingslayer) Lannister Brother to Tyrion and Cersei, as well as Cersei’s lover. Jaime is arrogant, short-tempered, and rash, but he’s also a gifted swordsman. He is widely mistrusted and called Kingslayer because he murdered the previous king. Petyr (Littlefinger) Baelish The Red Keep’s master of coin. He is shrewd, conniving, and selfish, and he keeps informed about everything that goes on in King’s Landing. He holds a grudge against the Starks because he wanted to marry Catelyn when he was younger. Varys (The Spider) The Red Keep’s master of whispers and a eunuch. His role in the court is to run a network of spies and keep the king informed, and he often uses what he knows to manipulate those around him, including the king. Robert Baratheon The corpulent king of Westeros. He loves to fight, drink, and sleep with women, and he hates the duties of ruling. He and Ned are long-time friends, and he was engaged to Ned’s sister until she died. Ser Jorah Mormont An exiled knight who serves unofficially as Daenerys’s chief advisor. Though he was exiled by Ned Stark for selling slaves, he is intelligent, valiant, and a great fighter. He swears allegiance to Viserys as true king of Westeros, but he also feeds information about the Targaryens back to Varys. Viserys Targaryen Brother of Daenerys and son of the murdered King Aerys Targaryen. Having lived in exile for many years, earning him the nickname of The Beggar King, he wants to return to Westeros and retake the throne. He is arrogant, cruel, easily angered, and foolish. Khal Drogo A powerful khal (king) among the Dothraki people and the husband of Daenerys Targaryen. Stoic and brave, Drogo is an exceptional warrior who shows his enemies no mercy. He controls a massive nomadic tribe, or khalasar. Prince Joffrey (Joff) Baratheon The repulsive prince of Westeros. The twelve-year-old Joff is the eldest child of Cersei and Robert, and he is spoiled, impulsive, and cruel when using his power as prince and heir to the throne. Sandor (The Hound) Clegane Prince Joff’s unofficial bodyguard. Proud that he is not a knight, The Hound appears to have no scruples whatsoever and does what Joffrey orders, however cruel or unjust, without question. His face is scarred on one side by extensive burning inflicted by his brother, Gregor. Robb Stark The eldest Stark son and thus heir to Ned Stark. Though just fourteen, he is mature beyond his age as well as being brave and dutiful like his father. Maester Luwin Counselor to Ned, Catelyn, and Robb. Luwin is old and wise, and his advice proves indispensible to the Starks. Theon Greyjoy The Starks’s ward and Robb’s best friend. Ned Stark took the young Theon, now nineteen, as a ward after putting down a rebellion led by the Greyjoy family, and Theon consequently grew up with the Stark children as something like a brother. Ser Rodrik Cassel Winterfell’s master-at-arms. He escorts and defends Catelyn on her journey to King’s Landing and to the Eyrie, tugging anxiously or thoughtfully at his whiskers the whole way. Tywin Lannister The calculating lord of Casterly Rock and the richest man in the realm. A fierce general, Tywin will go to great ends to protect the honor of the Lannister name. Bronn A sellsword, or mercenary, who saves Tyrion’s life many times over. Bronn is smart and skilled, and he knows a good deal when he sees one. Though he is an unscrupulous mercenary, he develops something of a friendship with Tyrion. Lysa Arryn The inconstant and irrational ruler of the Eyrie and sister of Catelyn Stark. Her paranoid, obsessive care of her only son, Robert, consumes her after her husband, Jon Arryn, the former Hand of the King, is murdered. Though she grew up with Catelyn, the two are now very different. Jeor Mormont (Commander Mormont) Lord Commander of the Night’s Watch at Castle Black. Commander Mormont is tough, old, and wise, and his men call him “The Old Bear.” Maester Aemon The chief man of learning at Castle Black. Despite his blind white eyes, Maester Aemon sees and speaks the truth in cryptic ways. Though few people realize it, Aemon is one of the few surviving members of the Targaryen family, but he has always put his vows to the Night’s Watch ahead of any family loyalties. Samwell (Sam) Tarly A new recruit to the Night’s Watch who is fat and cowardly but very smart. Sam loves to read and eat but hates to fight, and he quickly becomes one of Jon Snow’s closest companions at the Wall. Ser Allister Thorne Castle Black’s resentful master-at-arms. He hard on the new recruits to the Night’s Watch and seems to enjoy making them suffer, causing Jon to rebel against him. During Robert’s rebellion against the former king, he was a Targaryen loyalist. Illyrio Mopatis An obese merchant from the Free Cities who helps Daenerys and Viserys Targaryen. Illyrio is very rich and very well-informed. He is quick to please, especially when there is a possibility that his kindness will help him avoid trouble or gain greater fortune in the future. Ser Barristan Selmy Lord Commander of the Kingsguard. He has served kings Jaehaerys, Aerys II, and Robert. Though he has grown old, Barristan “The Bold” is a formidable fighter. He is, and has always been, an honorable knight. Renly Baratheon The youngest of the three Baratheon brothers. Renly is lighthearted and opportunistic, and unexpectedly ambitious. He serves on Robert’s royal council. Stannis Baratheon The middle brother of the three Baratheons. Stannis does not appear in A Game of Thrones, but as the brother of the king, he is a potential heir to the throne. Stannis does not seem to be well-liked. Ser Ilyn Payne The King’s Justice, meaning executioner. He has a frightful appearance, and he cannot speak since Aerys had his tongue ripped out with hot pincers. Though he is the king’s executioner, his family is loyal to House Lannister. Ser Gregor Cleagne The Hound’s older brother and a knight of the court. Called The Mountain that Rides, Ser Gregor is even larger and crueler than the Hound himself. He is also a sore loser and a marginal commander in battle. Osha A wildling woman who becomes a ward of the Starks after trying to kidnap Bran. She is tough and strong, and she takes care of Bran after her capture, telling him stories about life in the wild and warning him about what is happening north of the Wall. Rickon Stark The youngest of the Stark children. Three-year-old Rickon is wild and undisciplined, as is his pet direwolf. Aerys II Targaryen King of Westeros before Robert Baratheon. He was known as The Mad King because of his cruelty. Aerys murdered Ned’s older brother, Brandon Stark, in the Red Keep’s throne room. At the end of the war that followed, Jaime Lannister slew Aerys in the same room. Rhaegar Targaryen The heir to Aerys and older brother of Daenerys and Viserys. Rhaegar kidnapped Lyanna Stark, Robert’s betrothed, helping to set in motion the events that led to Robert’s Rebellion. The war effectively ended when Robert slew Rhaegar with his warhammer on the Trident River. Jon Arryn The recently deceased Lord of the Eyrie and Hand of the King. Jon Arryn fostered Ned Stark and Robert Baratheon at the Eyrie. When Robert became king, Jon Arryn served as his Hand until his murder. ================================================ FILE: py/core/examples/data/pg_essay_1.html ================================================ A Project of One's Own


A Project of One's Own

June 2021

A few days ago, on the way home from school, my nine year old son told me he couldn't wait to get home to write more of the story he was working on. This made me as happy as anything I've heard him say not just because he was excited about his story, but because he'd discovered this way of working. Working on a project of your own is as different from ordinary work as skating is from walking. It's more fun, but also much more productive.

What proportion of great work has been done by people who were skating in this sense? If not all of it, certainly a lot.

There is something special about working on a project of your own. I wouldn't say exactly that you're happier. A better word would be excited, or engaged. You're happy when things are going well, but often they aren't. When I'm writing an essay, most of the time I'm worried and puzzled: worried that the essay will turn out badly, and puzzled because I'm groping for some idea that I can't see clearly enough. Will I be able to pin it down with words? In the end I usually can, if I take long enough, but I'm never sure; the first few attempts often fail.

You have moments of happiness when things work out, but they don't last long, because then you're on to the next problem. So why do it at all? Because to the kind of people who like working this way, nothing else feels as right. You feel as if you're an animal in its natural habitat, doing what you were meant to do not always happy, maybe, but awake and alive.

Many kids experience the excitement of working on projects of their own. The hard part is making this converge with the work you do as an adult. And our customs make it harder. We treat "playing" and "hobbies" as qualitatively different from "work". It's not clear to a kid building a treehouse that there's a direct (though long) route from that to architecture or engineering. And instead of pointing out the route, we conceal it, by implicitly treating the stuff kids do as different from real work. [1]

Instead of telling kids that their treehouses could be on the path to the work they do as adults, we tell them the path goes through school. And unfortunately schoolwork tends to be very different from working on projects of one's own. It's usually neither a project, nor one's own. So as school gets more serious, working on projects of one's own is something that survives, if at all, as a thin thread off to the side.

It's a bit sad to think of all the high school kids turning their backs on building treehouses and sitting in class dutifully learning about Darwin or Newton to pass some exam, when the work that made Darwin and Newton famous was actually closer in spirit to building treehouses than studying for exams.

If I had to choose between my kids getting good grades and working on ambitious projects of their own, I'd pick the projects. And not because I'm an indulgent parent, but because I've been on the other end and I know which has more predictive value. When I was picking startups for Y Combinator, I didn't care about applicants' grades. But if they'd worked on projects of their own, I wanted to hear all about those. [2]

It may be inevitable that school is the way it is. I'm not saying we have to redesign it (though I'm not saying we don't), just that we should understand what it does to our attitudes to work that it steers us toward the dutiful plodding kind of work, often using competition as bait, and away from skating.

There are occasionally times when schoolwork becomes a project of one's own. Whenever I had to write a paper, that would become a project of my own except in English classes, ironically, because the things one has to write in English classes are so bogus. And when I got to college and started taking CS classes, the programs I had to write became projects of my own. Whenever I was writing or programming, I was usually skating, and that has been true ever since.

So where exactly is the edge of projects of one's own? That's an interesting question, partly because the answer is so complicated, and partly because there's so much at stake. There turn out to be two senses in which work can be one's own: 1) that you're doing it voluntarily, rather than merely because someone told you to, and 2) that you're doing it by yourself.

The edge of the former is quite sharp. People who care a lot about their work are usually very sensitive to the difference between pulling, and being pushed, and work tends to fall into one category or the other. But the test isn't simply whether you're told to do something. You can choose to do something you're told to do. Indeed, you can own it far more thoroughly than the person who told you to do it.

For example, math homework is for most people something they're told to do. But for my father, who was a mathematician, it wasn't. Most of us think of the problems in a math book as a way to test or develop our knowledge of the material explained in each section. But to my father the problems were the part that mattered, and the text was merely a sort of annotation. Whenever he got a new math book it was to him like being given a puzzle: here was a new set of problems to solve, and he'd immediately set about solving all of them.

The other sense of a project being one's own working on it by oneself has a much softer edge. It shades gradually into collaboration. And interestingly, it shades into collaboration in two different ways. One way to collaborate is to share a single project. For example, when two mathematicians collaborate on a proof that takes shape in the course of a conversation between them. The other way is when multiple people work on separate projects of their own that fit together like a jigsaw puzzle. For example, when one person writes the text of a book and another does the graphic design. [3]

These two paths into collaboration can of course be combined. But under the right conditions, the excitement of working on a project of one's own can be preserved for quite a while before disintegrating into the turbulent flow of work in a large organization. Indeed, the history of successful organizations is partly the history of techniques for preserving that excitement. [4]

The team that made the original Macintosh were a great example of this phenomenon. People like Burrell Smith and Andy Hertzfeld and Bill Atkinson and Susan Kare were not just following orders. They were not tennis balls hit by Steve Jobs, but rockets let loose by Steve Jobs. There was a lot of collaboration between them, but they all seem to have individually felt the excitement of working on a project of one's own.

In Andy Hertzfeld's book on the Macintosh, he describes how they'd come back into the office after dinner and work late into the night. People who've never experienced the thrill of working on a project they're excited about can't distinguish this kind of working long hours from the kind that happens in sweatshops and boiler rooms, but they're at opposite ends of the spectrum. That's why it's a mistake to insist dogmatically on "work/life balance." Indeed, the mere expression "work/life" embodies a mistake: it assumes work and life are distinct. For those to whom the word "work" automatically implies the dutiful plodding kind, they are. But for the skaters, the relationship between work and life would be better represented by a dash than a slash. I wouldn't want to work on anything that I didn't want to take over my life.

Of course, it's easier to achieve this level of motivation when you're making something like the Macintosh. It's easy for something new to feel like a project of your own. That's one of the reasons for the tendency programmers have to rewrite things that don't need rewriting, and to write their own versions of things that already exist. This sometimes alarms managers, and measured by total number of characters typed, it's rarely the optimal solution. But it's not always driven simply by arrogance or cluelessness. Writing code from scratch is also much more rewarding so much more rewarding that a good programmer can end up net ahead, despite the shocking waste of characters. Indeed, it may be one of the advantages of capitalism that it encourages such rewriting. A company that needs software to do something can't use the software already written to do it at another company, and thus has to write their own, which often turns out better. [5]

The natural alignment between skating and solving new problems is one of the reasons the payoffs from startups are so high. Not only is the market price of unsolved problems higher, you also get a discount on productivity when you work on them. In fact, you get a double increase in productivity: when you're doing a clean-sheet design, it's easier to recruit skaters, and they get to spend all their time skating.

Steve Jobs knew a thing or two about skaters from having watched Steve Wozniak. If you can find the right people, you only have to tell them what to do at the highest level. They'll handle the details. Indeed, they insist on it. For a project to feel like your own, you must have sufficient autonomy. You can't be working to order, or slowed down by bureaucracy.

One way to ensure autonomy is not to have a boss at all. There are two ways to do that: to be the boss yourself, and to work on projects outside of work. Though they're at opposite ends of the scale financially, startups and open source projects have a lot in common, including the fact that they're often run by skaters. And indeed, there's a wormhole from one end of the scale to the other: one of the best ways to discover startup ideas is to work on a project just for fun.

If your projects are the kind that make money, it's easy to work on them. It's harder when they're not. And the hardest part, usually, is morale. That's where adults have it harder than kids. Kids just plunge in and build their treehouse without worrying about whether they're wasting their time, or how it compares to other treehouses. And frankly we could learn a lot from kids here. The high standards most grownups have for "real" work do not always serve us well.

The most important phase in a project of one's own is at the beginning: when you go from thinking it might be cool to do x to actually doing x. And at that point high standards are not merely useless but positively harmful. There are a few people who start too many new projects, but far more, I suspect, who are deterred by fear of failure from starting projects that would have succeeded if they had.

But if we couldn't benefit as kids from the knowledge that our treehouses were on the path to grownup projects, we can at least benefit as grownups from knowing that our projects are on a path that stretches back to treehouses. Remember that careless confidence you had as a kid when starting something new? That would be a powerful thing to recapture.

If it's harder as adults to retain that kind of confidence, we at least tend to be more aware of what we're doing. Kids bounce, or are herded, from one kind of work to the next, barely realizing what's happening to them. Whereas we know more about different types of work and have more control over which we do. Ideally we can have the best of both worlds: to be deliberate in choosing to work on projects of our own, and carelessly confident in starting new ones.









Notes

[1] "Hobby" is a curious word. Now it means work that isn't real work work that one is not to be judged by but originally it just meant an obsession in a fairly general sense (even a political opinion, for example) that one metaphorically rode as a child rides a hobby-horse. It's hard to say if its recent, narrower meaning is a change for the better or the worse. For sure there are lots of false positives lots of projects that end up being important but are dismissed initially as mere hobbies. But on the other hand, the concept provides valuable cover for projects in the early, ugly duckling phase.

[2] Tiger parents, as parents so often do, are fighting the last war. Grades mattered more in the old days when the route to success was to acquire credentials while ascending some predefined ladder. But it's just as well that their tactics are focused on grades. How awful it would be if they invaded the territory of projects, and thereby gave their kids a distaste for this kind of work by forcing them to do it. Grades are already a grim, fake world, and aren't harmed much by parental interference, but working on one's own projects is a more delicate, private thing that could be damaged very easily.

[3] The complicated, gradual edge between working on one's own projects and collaborating with others is one reason there is so much disagreement about the idea of the "lone genius." In practice people collaborate (or not) in all kinds of different ways, but the idea of the lone genius is definitely not a myth. There's a core of truth to it that goes with a certain way of working.

[4] Collaboration is powerful too. The optimal organization would combine collaboration and ownership in such a way as to do the least damage to each. Interestingly, companies and university departments approach this ideal from opposite directions: companies insist on collaboration, and occasionally also manage both to recruit skaters and allow them to skate, and university departments insist on the ability to do independent research (which is by custom treated as skating, whether it is or not), and the people they hire collaborate as much as they choose.

[5] If a company could design its software in such a way that the best newly arrived programmers always got a clean sheet, it could have a kind of eternal youth. That might not be impossible. If you had a software backbone defining a game with sufficiently clear rules, individual programmers could write their own players.

Fierce Nerds

May 2021

Most people think of nerds as quiet, diffident people. In ordinary social situations they are as quiet and diffident as the star quarterback would be if he found himself in the middle of a physics symposium. And for the same reason: they are fish out of water. But the apparent diffidence of nerds is an illusion due to the fact that when non-nerds observe them, it's usually in ordinary social situations. In fact some nerds are quite fierce.

The fierce nerds are a small but interesting group. They are as a rule extremely competitive more competitive, I'd say, than highly competitive non-nerds. Competition is more personal for them. Partly perhaps because they're not emotionally mature enough to distance themselves from it, but also because there's less randomness in the kinds of competition they engage in, and they are thus more justified in taking the results personally.

Fierce nerds also tend to be somewhat overconfident, especially when young. It might seem like it would be a disadvantage to be mistaken about one's abilities, but empirically it isn't. Up to a point, confidence is a self-fullfilling prophecy.

Another quality you find in most fierce nerds is intelligence. Not all nerds are smart, but the fierce ones are always at least moderately so. If they weren't, they wouldn't have the confidence to be fierce. [1]

There's also a natural connection between nerdiness and independent-mindedness. It's hard to be independent-minded without being somewhat socially awkward, because conventional beliefs are so often mistaken, or at least arbitrary. No one who was both independent-minded and ambitious would want to waste the effort it takes to fit in. And the independent-mindedness of the fierce nerds will obviously be of the aggressive rather than the passive type: they'll be annoyed by rules, rather than dreamily unaware of them.

I'm less sure why fierce nerds are impatient, but most seem to be. You notice it first in conversation, where they tend to interrupt you. This is merely annoying, but in the more promising fierce nerds it's connected to a deeper impatience about solving problems. Perhaps the competitiveness and impatience of fierce nerds are not separate qualities, but two manifestations of a single underlying drivenness.

When you combine all these qualities in sufficient quantities, the result is quite formidable. The most vivid example of fierce nerds in action may be James Watson's The Double Helix. The first sentence of the book is "I have never seen Francis Crick in a modest mood," and the portrait he goes on to paint of Crick is the quintessential fierce nerd: brilliant, socially awkward, competitive, independent-minded, overconfident. But so is the implicit portrait he paints of himself. Indeed, his lack of social awareness makes both portraits that much more realistic, because he baldly states all sorts of opinions and motivations that a smoother person would conceal. And moreover it's clear from the story that Crick and Watson's fierce nerdiness was integral to their success. Their independent-mindedness caused them to consider approaches that most others ignored, their overconfidence allowed them to work on problems they only half understood (they were literally described as "clowns" by one eminent insider), and their impatience and competitiveness got them to the answer ahead of two other groups that would otherwise have found it within the next year, if not the next several months. [2]

The idea that there could be fierce nerds is an unfamiliar one not just to many normal people but even to some young nerds. Especially early on, nerds spend so much of their time in ordinary social situations and so little doing real work that they get a lot more evidence of their awkwardness than their power. So there will be some who read this description of the fierce nerd and realize "Hmm, that's me." And it is to you, young fierce nerd, that I now turn.

I have some good news, and some bad news. The good news is that your fierceness will be a great help in solving difficult problems. And not just the kind of scientific and technical problems that nerds have traditionally solved. As the world progresses, the number of things you can win at by getting the right answer increases. Recently getting rich became one of them: 7 of the 8 richest people in America are now fierce nerds.

Indeed, being a fierce nerd is probably even more helpful in business than in nerds' original territory of scholarship. Fierceness seems optional there. Darwin for example doesn't seem to have been especially fierce. Whereas it's impossible to be the CEO of a company over a certain size without being fierce, so now that nerds can win at business, fierce nerds will increasingly monopolize the really big successes.

The bad news is that if it's not exercised, your fierceness will turn to bitterness, and you will become an intellectual playground bully: the grumpy sysadmin, the forum troll, the hater, the shooter down of new ideas.

How do you avoid this fate? Work on ambitious projects. If you succeed, it will bring you a kind of satisfaction that neutralizes bitterness. But you don't need to have succeeded to feel this; merely working on hard projects gives most fierce nerds some feeling of satisfaction. And those it doesn't, it at least keeps busy. [3]

Another solution may be to somehow turn off your fierceness, by devoting yourself to meditation or psychotherapy or something like that. Maybe that's the right answer for some people. I have no idea. But it doesn't seem the optimal solution to me. If you're given a sharp knife, it seems to me better to use it than to blunt its edge to avoid cutting yourself.

If you do choose the ambitious route, you'll have a tailwind behind you. There has never been a better time to be a nerd. In the past century we've seen a continuous transfer of power from dealmakers to technicians from the charismatic to the competent and I don't see anything on the horizon that will end it. At least not till the nerds end it themselves by bringing about the singularity.









Notes

[1] To be a nerd is to be socially awkward, and there are two distinct ways to do that: to be playing the same game as everyone else, but badly, and to be playing a different game. The smart nerds are the latter type.

[2] The same qualities that make fierce nerds so effective can also make them very annoying. Fierce nerds would do well to remember this, and (a) try to keep a lid on it, and (b) seek out organizations and types of work where getting the right answer matters more than preserving social harmony. In practice that means small groups working on hard problems. Which fortunately is the most fun kind of environment anyway.

[3] If success neutralizes bitterness, why are there some people who are at least moderately successful and yet still quite bitter? Because people's potential bitterness varies depending on how naturally bitter their personality is, and how ambitious they are: someone who's naturally very bitter will still have a lot left after success neutralizes some of it, and someone who's very ambitious will need proportionally more success to satisfy that ambition.

So the worst-case scenario is someone who's both naturally bitter and extremely ambitious, and yet only moderately successful.

There's one kind of opinion I'd be very afraid to express publicly. If someone I knew to be both a domain expert and a reasonable person proposed an idea that sounded preposterous, I'd be very reluctant to say "That will never work."

Anyone who has studied the history of ideas, and especially the history of science, knows that's how big things start. Someone proposes an idea that sounds crazy, most people dismiss it, then it gradually takes over the world.

Most implausible-sounding ideas are in fact bad and could be safely dismissed. But not when they're proposed by reasonable domain experts. If the person proposing the idea is reasonable, then they know how implausible it sounds. And yet they're proposing it anyway. That suggests they know something you don't. And if they have deep domain expertise, that's probably the source of it. [1]

Such ideas are not merely unsafe to dismiss, but disproportionately likely to be interesting. When the average person proposes an implausible-sounding idea, its implausibility is evidence of their incompetence. But when a reasonable domain expert does it, the situation is reversed. There's something like an efficient market here: on average the ideas that seem craziest will, if correct, have the biggest effect. So if you can eliminate the theory that the person proposing an implausible-sounding idea is incompetent, its implausibility switches from evidence that it's boring to evidence that it's exciting. [2]

Such ideas are not guaranteed to work. But they don't have to be. They just have to be sufficiently good bets to have sufficiently high expected value. And I think on average they do. I think if you bet on the entire set of implausible-sounding ideas proposed by reasonable domain experts, you'd end up net ahead.

The reason is that everyone is too conservative. The word "paradigm" is overused, but this is a case where it's warranted. Everyone is too much in the grip of the current paradigm. Even the people who have the new ideas undervalue them initially. Which means that before they reach the stage of proposing them publicly, they've already subjected them to an excessively strict filter. [3]

The wise response to such an idea is not to make statements, but to ask questions, because there's a real mystery here. Why has this smart and reasonable person proposed an idea that seems so wrong? Are they mistaken, or are you? One of you has to be. If you're the one who's mistaken, that would be good to know, because it means there's a hole in your model of the world. But even if they're mistaken, it should be interesting to learn why. A trap that an expert falls into is one you have to worry about too.

This all seems pretty obvious. And yet there are clearly a lot of people who don't share my fear of dismissing new ideas. Why do they do it? Why risk looking like a jerk now and a fool later, instead of just reserving judgement?

One reason they do it is envy. If you propose a radical new idea and it succeeds, your reputation (and perhaps also your wealth) will increase proportionally. Some people would be envious if that happened, and this potential envy propagates back into a conviction that you must be wrong.

Another reason people dismiss new ideas is that it's an easy way to seem sophisticated. When a new idea first emerges, it usually seems pretty feeble. It's a mere hatchling. Received wisdom is a full-grown eagle by comparison. So it's easy to launch a devastating attack on a new idea, and anyone who does will seem clever to those who don't understand this asymmetry.

This phenomenon is exacerbated by the difference between how those working on new ideas and those attacking them are rewarded. The rewards for working on new ideas are weighted by the value of the outcome. So it's worth working on something that only has a 10% chance of succeeding if it would make things more than 10x better. Whereas the rewards for attacking new ideas are roughly constant; such attacks seem roughly equally clever regardless of the target.

People will also attack new ideas when they have a vested interest in the old ones. It's not surprising, for example, that some of Darwin's harshest critics were churchmen. People build whole careers on some ideas. When someone claims they're false or obsolete, they feel threatened.

The lowest form of dismissal is mere factionalism: to automatically dismiss any idea associated with the opposing faction. The lowest form of all is to dismiss an idea because of who proposed it.

But the main thing that leads reasonable people to dismiss new ideas is the same thing that holds people back from proposing them: the sheer pervasiveness of the current paradigm. It doesn't just affect the way we think; it is the Lego blocks we build thoughts out of. Popping out of the current paradigm is something only a few people can do. And even they usually have to suppress their intuitions at first, like a pilot flying through cloud who has to trust his instruments over his sense of balance. [4]

Paradigms don't just define our present thinking. They also vacuum up the trail of crumbs that led to them, making our standards for new ideas impossibly high. The current paradigm seems so perfect to us, its offspring, that we imagine it must have been accepted completely as soon as it was discovered that whatever the church thought of the heliocentric model, astronomers must have been convinced as soon as Copernicus proposed it. Far, in fact, from it. Copernicus published the heliocentric model in 1532, but it wasn't till the mid seventeenth century that the balance of scientific opinion shifted in its favor. [5]

Few understand how feeble new ideas look when they first appear. So if you want to have new ideas yourself, one of the most valuable things you can do is to learn what they look like when they're born. Read about how new ideas happened, and try to get yourself into the heads of people at the time. How did things look to them, when the new idea was only half-finished, and even the person who had it was only half-convinced it was right?

But you don't have to stop at history. You can observe big new ideas being born all around you right now. Just look for a reasonable domain expert proposing something that sounds wrong.

If you're nice, as well as wise, you won't merely resist attacking such people, but encourage them. Having new ideas is a lonely business. Only those who've tried it know how lonely. These people need your help. And if you help them, you'll probably learn something in the process.









Notes

[1] This domain expertise could be in another field. Indeed, such crossovers tend to be particularly promising.

[2] I'm not claiming this principle extends much beyond math, engineering, and the hard sciences. In politics, for example, crazy-sounding ideas generally are as bad as they sound. Though arguably this is not an exception, because the people who propose them are not in fact domain experts; politicians are domain experts in political tactics, like how to get elected and how to get legislation passed, but not in the world that policy acts upon. Perhaps no one could be.

[3] This sense of "paradigm" was defined by Thomas Kuhn in his Structure of Scientific Revolutions, but I also recommend his Copernican Revolution, where you can see him at work developing the idea.

[4] This is one reason people with a touch of Asperger's may have an advantage in discovering new ideas. They're always flying on instruments.

An NFT That Saves Lives

May 2021

Noora Health, a nonprofit I've supported for years, just launched a new NFT. It has a dramatic name, Save Thousands of Lives, because that's what the proceeds will do.

Noora has been saving lives for 7 years. They run programs in hospitals in South Asia to teach new mothers how to take care of their babies once they get home. They're in 165 hospitals now. And because they know the numbers before and after they start at a new hospital, they can measure the impact they have. It is massive. For every 1000 live births, they save 9 babies.

This number comes from a study of 133,733 families at 28 different hospitals that Noora conducted in collaboration with the Better Birth team at Ariadne Labs, a joint center for health systems innovation at Brigham and Womens Hospital and Harvard T.H. Chan School of Public Health.

Noora is so effective that even if you measure their costs in the most conservative way, by dividing their entire budget by the number of lives saved, the cost of saving a life is the lowest I've seen. $1,235.

For this NFT, they're going to issue a public report tracking how this specific tranche of money is spent, and estimating the number of lives saved as a result.

NFTs are a new territory, and this way of using them is especially new, but I'm excited about its potential. And I'm excited to see what happens with this particular auction, because unlike an NFT representing something that has already happened, this NFT gets better as the price gets higher.

The reserve price was about $2.5 million, because that's what it takes for the name to be accurate: that's what it costs to save 2000 lives. But the higher the price of this NFT goes, the more lives will be saved. What a sentence to be able to write.

The Real Reason to End the Death Penalty

April 2021

When intellectuals talk about the death penalty, they talk about things like whether it's permissible for the state to take someone's life, whether the death penalty acts as a deterrent, and whether more death sentences are given to some groups than others. But in practice the debate about the death penalty is not about whether it's ok to kill murderers. It's about whether it's ok to kill innocent people, because at least 4% of people on death row are innocent.

When I was a kid I imagined that it was unusual for people to be convicted of crimes they hadn't committed, and that in murder cases especially this must be very rare. Far from it. Now, thanks to organizations like the Innocence Project, we see a constant stream of stories about murder convictions being overturned after new evidence emerges. Sometimes the police and prosecutors were just very sloppy. Sometimes they were crooked, and knew full well they were convicting an innocent person.

Kenneth Adams and three other men spent 18 years in prison on a murder conviction. They were exonerated after DNA testing implicated three different men, two of whom later confessed. The police had been told about the other men early in the investigation, but never followed up the lead.

Keith Harward spent 33 years in prison on a murder conviction. He was convicted because "experts" said his teeth matched photos of bite marks on one victim. He was exonerated after DNA testing showed the murder had been committed by another man, Jerry Crotty.

Ricky Jackson and two other men spent 39 years in prison after being convicted of murder on the testimony of a 12 year old boy, who later recanted and said he'd been coerced by police. Multiple people have confirmed the boy was elsewhere at the time. The three men were exonerated after the county prosecutor dropped the charges, saying "The state is conceding the obvious."

Alfred Brown spent 12 years in prison on a murder conviction, including 10 years on death row. He was exonerated after it was discovered that the agent district attorney had concealed phone records proving he could not have committed the crimes.

Glenn Ford spent 29 years on death row after having been convicted of murder. He was exonerated after new evidence proved he was not even at the scene when the murder occurred. The attorneys assigned to represent him had never tried a jury case before.

Cameron Willingham was actually executed in 2004 by lethal injection. The "expert" who testified that he deliberately set fire to his house has since been discredited. A re-examination of the case ordered by the state of Texas in 2009 concluded that "a finding of arson could not be sustained."

Rich Glossip has spent 20 years on death row after being convicted of murder on the testimony of the actual killer, who escaped with a life sentence in return for implicating him. In 2015 he came within minutes of execution before it emerged that Oklahoma had been planning to kill him with an illegal combination of drugs. They still plan to go ahead with the execution, perhaps as soon as this summer, despite new evidence exonerating him.

I could go on. There are hundreds of similar cases. In Florida alone, 29 death row prisoners have been exonerated so far.

Far from being rare, wrongful murder convictions are very common. Police are under pressure to solve a crime that has gotten a lot of attention. When they find a suspect, they want to believe he's guilty, and ignore or even destroy evidence suggesting otherwise. District attorneys want to be seen as effective and tough on crime, and in order to win convictions are willing to manipulate witnesses and withhold evidence. Court-appointed defense attorneys are overworked and often incompetent. There's a ready supply of criminals willing to give false testimony in return for a lighter sentence, suggestible witnesses who can be made to say whatever police want, and bogus "experts" eager to claim that science proves the defendant is guilty. And juries want to believe them, since otherwise some terrible crime remains unsolved.

This circus of incompetence and dishonesty is the real issue with the death penalty. We don't even reach the point where theoretical questions about the moral justification or effectiveness of capital punishment start to matter, because so many of the people sentenced to death are actually innocent. Whatever it means in theory, in practice capital punishment means killing innocent people.

Readability, however, is emphasized above all else. A Markdown-formatted document should be publishable as-is, as plain text, without looking like it's been marked up with tags or formatting instructions. While Markdown's syntax has been influenced by several existing text-to-HTML filters -- including [Setext](http://docutils.sourceforge.net/mirror/setext.html), [atx](http://www.aaronsw.com/2002/atx/), [Textile](http://textism.com/tools/textile/), [reStructuredText](http://docutils.sourceforge.net/rst.html), [Grutatext](http://www.triptico.com/software/grutatxt.html), and [EtText](http://ettext.taint.org/doc/) -- the single biggest source of inspiration for Markdown's syntax is the format of plain text email. ## Block Elements ### Paragraphs and Line Breaks A paragraph is simply one or more consecutive lines of text, separated by one or more blank lines. (A blank line is any line that looks like a blank line -- a line containing nothing but spaces or tabs is considered blank.) Normal paragraphs should not be indented with spaces or tabs. The implication of the "one or more consecutive lines of text" rule is that Markdown supports "hard-wrapped" text paragraphs. This differs significantly from most other text-to-HTML formatters (including Movable Type's "Convert Line Breaks" option) which translate every line break character in a paragraph into a `
` tag. When you *do* want to insert a `
` break tag using Markdown, you end a line with two or more spaces, then type return. ### Headers Markdown supports two styles of headers, [Setext] [1] and [atx] [2]. Optionally, you may "close" atx-style headers. This is purely cosmetic -- you can use this if you think it looks better. The closing hashes don't even need to match the number of hashes used to open the header. (The number of opening hashes determines the header level.) ### Blockquotes Markdown uses email-style `>` characters for blockquoting. If you're familiar with quoting passages of text in an email message, then you know how to create a blockquote in Markdown. It looks best if you hard wrap the text and put a `>` before every line: > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet, > consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. > Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. > > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse > id sem consectetuer libero luctus adipiscing. Markdown allows you to be lazy and only put the `>` before the first line of a hard-wrapped paragraph: > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse id sem consectetuer libero luctus adipiscing. Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by adding additional levels of `>`: > This is the first level of quoting. > > > This is nested blockquote. > > Back to the first level. Blockquotes can contain other Markdown elements, including headers, lists, and code blocks: > ## This is a header. > > 1. This is the first list item. > 2. This is the second list item. > > Here's some example code: > > return shell_exec("echo $input | $markdown_script"); Any decent text editor should make email-style quoting easy. For example, with BBEdit, you can make a selection and choose Increase Quote Level from the Text menu. ### Lists Markdown supports ordered (numbered) and unordered (bulleted) lists. Unordered lists use asterisks, pluses, and hyphens -- interchangably -- as list markers: * Red * Green * Blue is equivalent to: + Red + Green + Blue and: - Red - Green - Blue Ordered lists use numbers followed by periods: 1. Bird 2. McHale 3. Parish It's important to note that the actual numbers you use to mark the list have no effect on the HTML output Markdown produces. The HTML Markdown produces from the above list is: If you instead wrote the list in Markdown like this: 1. Bird 1. McHale 1. Parish or even: 3. Bird 1. McHale 8. Parish you'd get the exact same HTML output. The point is, if you want to, you can use ordinal numbers in your ordered Markdown lists, so that the numbers in your source match the numbers in your published HTML. But if you want to be lazy, you don't have to. To make lists look nice, you can wrap items with hanging indents: * Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. * Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse id sem consectetuer libero luctus adipiscing. But if you want to be lazy, you don't have to: * Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. * Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse id sem consectetuer libero luctus adipiscing. List items may consist of multiple paragraphs. Each subsequent paragraph in a list item must be indented by either 4 spaces or one tab: 1. This is a list item with two paragraphs. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. Donec sit amet nisl. Aliquam semper ipsum sit amet velit. 2. Suspendisse id sem consectetuer libero luctus adipiscing. It looks nice if you indent every line of the subsequent paragraphs, but here again, Markdown will allow you to be lazy: * This is a list item with two paragraphs. This is the second paragraph in the list item. You're only required to indent the first line. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. * Another item in the same list. To put a blockquote within a list item, the blockquote's `>` delimiters need to be indented: * A list item with a blockquote: > This is a blockquote > inside a list item. To put a code block within a list item, the code block needs to be indented *twice* -- 8 spaces or two tabs: * A list item with a code block: ### Code Blocks Pre-formatted code blocks are used for writing about programming or markup source code. Rather than forming normal paragraphs, the lines of a code block are interpreted literally. Markdown wraps a code block in both `
` and `` tags.

To produce a code block in Markdown, simply indent every line of the
block by at least 4 spaces or 1 tab.

This is a normal paragraph:

    This is a code block.

Here is an example of AppleScript:

    tell application "Foo"
        beep
    end tell

A code block continues until it reaches a line that is not indented
(or the end of the article).

Within a code block, ampersands (`&`) and angle brackets (`<` and `>`)
are automatically converted into HTML entities. This makes it very
easy to include example HTML source code using Markdown -- just paste
it and indent it, and Markdown will handle the hassle of encoding the
ampersands and angle brackets. For example, this:

    

        © 2004 Foo Corporation
    


Regular Markdown syntax is not processed within code blocks. E.g.,
asterisks are just literal asterisks within a code block. This means
it's also easy to use Markdown to write about Markdown's own syntax.

```
tell application "Foo"
    beep
end tell
```

## Span Elements

### Links

Markdown supports two style of links: *inline* and *reference*.

In both styles, the link text is delimited by [square brackets].

To create an inline link, use a set of regular parentheses immediately
after the link text's closing square bracket. Inside the parentheses,
put the URL where you want the link to point, along with an *optional*
title for the link, surrounded in quotes. For example:

This is [an example](http://example.com/) inline link.

[This link](http://example.net/) has no title attribute.

### Emphasis

Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
emphasis. Text wrapped with one `*` or `_` will be wrapped with an
HTML `` tag; double `*`'s or `_`'s will be wrapped with an HTML
`` tag. E.g., this input:

*single asterisks*

_single underscores_

**double asterisks**

__double underscores__

### Code

To indicate a span of code, wrap it with backtick quotes (`` ` ``).
Unlike a pre-formatted code block, a code span indicates code within a
normal paragraph. For example:

Use the `printf()` function.

Quod equidem non reprehendo;
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quibus natura iure responderit non esse verum aliunde finem beate vivendi, a se principia rei gerendae peti; Quae enim adhuc protulisti, popularia sunt, ego autem a te elegantiora desidero. Duo Reges: constructio interrete. Tum Lucius: Mihi vero ista valde probata sunt, quod item fratri puto. Bestiarum vero nullum iudicium puto. Nihil enim iam habes, quod ad corpus referas; Deinde prima illa, quae in congressu solemus: Quid tu, inquit, huc? Et homini, qui ceteris animantibus plurimum praestat, praecipue a natura nihil datum esse dicemus?

Iam id ipsum absurdum, maximum malum neglegi. Quod ea non occurrentia fingunt, vincunt Aristonem; Atqui perspicuum est hominem e corpore animoque constare, cum primae sint animi partes, secundae corporis. Fieri, inquam, Triari, nullo pacto potest, ut non dicas, quid non probes eius, a quo dissentias. Equidem e Cn. An dubium est, quin virtus ita maximam partem optineat in rebus humanis, ut reliquas obruat?

Quis istum dolorem timet?
Summus dolor plures dies manere non potest? Dicet pro me ipsa virtus nec dubitabit isti vestro beato M. Tubulum fuisse, qua illum, cuius is condemnatus est rogatione, P. Quod si ita sit, cur opera philosophiae sit danda nescio.

Ex eorum enim scriptis et institutis cum omnis doctrina liberalis, omnis historia.
Quod si ita est, sequitur id ipsum, quod te velle video, omnes semper beatos esse sapientes. Cum enim fertur quasi torrens oratio, quamvis multa cuiusque modi rapiat, nihil tamen teneas, nihil apprehendas, nusquam orationem rapidam coerceas. Ita redarguitur ipse a sese, convincunturque scripta eius probitate ipsius ac moribus. At quanta conantur! Mundum hunc omnem oppidum esse nostrum! Incendi igitur eos, qui audiunt, vides. Vide, ne magis, inquam, tuum fuerit, cum re idem tibi, quod mihi, videretur, non nova te rebus nomina inponere. Qui-vere falsone, quaerere mittimus-dicitur oculis se privasse; Si ista mala sunt, in quae potest incidere sapiens, sapientem esse non esse ad beate vivendum satis. At vero si ad vitem sensus accesserit, ut appetitum quendam habeat et per se ipsa moveatur, quid facturam putas?

Quem si tenueris, non modo meum Ciceronem, sed etiam me ipsum abducas licebit.
Stulti autem malorum memoria torquentur, sapientes bona praeterita grata recordatione renovata delectant.
Esse enim quam vellet iniquus iustus poterat inpune.
Quae autem natura suae primae institutionis oblita est?
Verum tamen cum de rebus grandioribus dicas, ipsae res verba rapiunt;
Hoc est non modo cor non habere, sed ne palatum quidem.
Voluptatem cum summum bonum diceret, primum in eo ipso parum vidit, deinde hoc quoque alienum; Sed tu istuc dixti bene Latine, parum plane. Nam haec ipsa mihi erunt in promptu, quae modo audivi, nec ante aggrediar, quam te ab istis, quos dicis, instructum videro. Fatebuntur Stoici haec omnia dicta esse praeclare, neque eam causam Zenoni desciscendi fuisse. Non autem hoc: igitur ne illud quidem. Ratio quidem vestra sic cogit. Cum audissem Antiochum, Brute, ut solebam, cum M. An quod ita callida est, ut optime possit architectari voluptates?

Idemne, quod iucunde?
Haec mihi videtur delicatior, ut ita dicam, molliorque ratio, quam virtutis vis gravitasque postulat. Sed quoniam et advesperascit et mihi ad villam revertendum est, nunc quidem hactenus; Cuius ad naturam apta ratio vera illa et summa lex a philosophis dicitur. Neque solum ea communia, verum etiam paria esse dixerunt. Sed nunc, quod agimus; A mene tu?

            Communities are created through the following process:
            1. Analyzes entity relationships and metadata to build a similarity graph
            2. Applies advanced community detection algorithms (e.g. Leiden) to identify densely connected groups
            3. Creates hierarchical community structure with multiple granularity levels
            4. Generates natural language summaries and statistical insights for each community

            The resulting communities can be used to:
            - Understand high-level graph structure and organization
            - Identify key entity groupings and their relationships
            - Navigate and explore the graph at different levels of detail
            - Generate insights about entity clusters and their characteristics

            table. Allowed tables include 'vectors', 'entity',
            'document_collections'. Vectors correspond to the chunks of text
            that are indexed for similarity search, whereas entity and
            document_collections are created during knowledge graph
            construction.

            This endpoint creates a database index optimized for efficient similarity search over vector embeddings.
            It supports two main indexing methods:

            1. HNSW (Hierarchical Navigable Small World):
               - Best for: High-dimensional vectors requiring fast approximate nearest neighbor search
               - Pros: Very fast search, good recall, memory-resident for speed
               - Cons: Slower index construction, more memory usage
               - Key parameters:
                 * m: Number of connections per layer (higher = better recall but more memory)
                 * ef_construction: Build-time search width (higher = better recall but slower build)
                 * ef: Query-time search width (higher = better recall but slower search)

            2. IVF-Flat (Inverted File with Flat Storage):
               - Best for: Balance between build speed, search speed, and recall
               - Pros: Faster index construction, less memory usage
               - Cons: Slightly slower search than HNSW
               - Key parameters:
                 * lists: Number of clusters (usually sqrt(n) where n is number of vectors)
                 * probe: Number of nearest clusters to search

            Supported similarity measures:
            - cosine_distance: Best for comparing semantic similarity
            - l2_distance: Best for comparing absolute distances
            - ip_distance: Best for comparing raw dot products

            Notes:
            - Index creation can be resource-intensive for large datasets
            - Use run_with_orchestration=True for large indices to prevent timeouts
            - The 'concurrently' option allows other operations while building
            - Index names must be unique per table

            """Perform a search query against vector and/or graph-based
            databases.

            **Search Modes:**
            - `basic`: Defaults to semantic search. Simple and easy to use.
            - `advanced`: Combines semantic search with full-text search for more comprehensive results.
            - `custom`: Complete control over how search is performed. Provide a full `SearchSettings` object.

            **Filters:**
            Apply filters directly inside `search_settings.filters`. For example:
            ```json
            {
            "filters": {"document_id": {"$eq": "e43864f5-a36f-548e-aacd-6f8d48b30c7f"}}
            }
            ```
            Supported operators: `$eq`, `$neq`, `$gt`, `$gte`, `$lt`, `$lte`, `$like`, `$ilike`, `$in`, `$nin`.

            **Hybrid Search:**
            Enable hybrid search by setting `use_hybrid_search: true` in search_settings. This combines semantic search with
            keyword-based search for improved results. Configure with `hybrid_settings`:
            ```json
            {
            "use_hybrid_search": true,
            "hybrid_settings": {
                "full_text_weight": 1.0,
                "semantic_weight": 5.0,
                "full_text_limit": 200,
                "rrf_k": 50
            }
            }
            ```

            **Graph-Enhanced Search:**
            Knowledge graph integration is enabled by default. Control with `graph_search_settings`:
            ```json
            {
            "graph_search_settings": {
                "use_graph_search": true,
                "kg_search_type": "local"
            }
            }
            ```

            **Advanced Filtering:**
            Use complex filters to narrow down results by metadata fields or document properties:
            ```json
            {
            "filters": {
                "$and":[
                    {"document_type": {"$eq": "pdf"}},
                    {"metadata.year": {"$gt": 2020}}
                ]
            }
            }
            ```

            **Results:**
            The response includes vector search results and optional graph search results.
            Each result contains the matched text, document ID, and relevance score.

            This endpoint combines search results with language model generation to produce accurate,
            contextually-relevant responses based on your document corpus.

            **Features:**
            - Combines vector search, optional knowledge graph integration, and LLM generation
            - Automatically cites sources with unique citation identifiers
            - Supports both streaming and non-streaming responses
            - Compatible with various LLM providers (OpenAI, Anthropic, etc.)
            - Web search integration for up-to-date information

            **Search Configuration:**
            All search parameters from the search endpoint apply here, including filters, hybrid search, and graph-enhanced search.

            **Generation Configuration:**
            Fine-tune the language model's behavior with `rag_generation_config`:
            ```json
            {
                "model": "openai/gpt-4.1-mini",  // Model to use
                "temperature": 0.7,              // Control randomness (0-1)
                "max_tokens": 1500,              // Maximum output length
                "stream": true                   // Enable token streaming
            }
            ```

            **Model Support:**
            - OpenAI models (default)
            - Anthropic Claude models (requires ANTHROPIC_API_KEY)
            - Local models via Ollama
            - Any provider supported by LiteLLM

            **Streaming Responses:**
            When `stream: true` is set, the endpoint returns Server-Sent Events with the following types:
            - `search_results`: Initial search results from your documents
            - `message`: Partial tokens as they're generated
            - `citation`: Citation metadata when sources are referenced
            - `final_answer`: Complete answer with structured citations

            **Example Response:**
            ```json
            {
            "generated_answer": "DeepSeek-R1 is a model that demonstrates impressive performance...[1]",

            Engage with an intelligent agent for information retrieval, analysis, and research.

            This endpoint offers two operating modes:
            - **RAG mode**: Standard retrieval-augmented generation for answering questions based on knowledge base
            - **Research mode**: Advanced capabilities for deep analysis, reasoning, and computation

            ### RAG Mode (Default)

            The RAG mode provides fast, knowledge-based responses using:
            - Semantic and hybrid search capabilities
            - Document-level and chunk-level content retrieval
            - Optional web search integration
            - Source citation and evidence-based responses

            ### Research Mode

            The Research mode builds on RAG capabilities and adds:
            - A dedicated reasoning system for complex problem-solving
            - Critique capabilities to identify potential biases or logical fallacies
            - Python execution for computational analysis
            - Multi-step reasoning for deeper exploration of topics

            ### Available Tools

            **RAG Tools:**
            - `search_file_knowledge`: Semantic/hybrid search on your ingested documents
            - `search_file_descriptions`: Search over file-level metadata
            - `content`: Fetch entire documents or chunk structures
            - `web_search`: Query external search APIs for up-to-date information
            - `web_scrape`: Scrape and extract content from specific web pages

            **Research Tools:**
            - `rag`: Leverage the underlying RAG agent for information retrieval
            - `reasoning`: Call a dedicated model for complex analytical thinking
            - `critique`: Analyze conversation history to identify flaws and biases
            - `python_executor`: Execute Python code for complex calculations and analysis

            ### Streaming Output

            When streaming is enabled, the agent produces different event types:
            - `thinking`: Shows the model's step-by-step reasoning (when extended_thinking=true)
            - `tool_call`: Shows when the agent invokes a tool
            - `tool_result`: Shows the result of a tool call
            - `citation`: Indicates when a citation is added to the response
            - `message`: Streams partial tokens of the response
            - `final_answer`: Contains the complete generated answer and structured citations

            ### Conversations

            Maintain context across multiple turns by including `conversation_id` in each request.
            After your first call, store the returned `conversation_id` and include it in subsequent calls.
            If no conversation name has already been set for the conversation, the system will automatically assign one.

        Note:
            When `vecs` creates an index on a pgvector column in PostgreSQL, it uses a multi-step
            process that enables performant indexes to be built for large collections with low end
            database hardware.

            Those steps are:

            - Creates a new table with a different name
            - Randomly selects records from the existing table
            - Inserts the random records from the existing table into the new table
            - Creates the requested vector index on the new table
            - Upserts all data from the existing table into the new table
            - Drops the existing table
            - Renames the new table to the existing tables name

            If you create dependencies (like views) on the table that underpins
            a `vecs.Collection` the `create_index` step may require you to drop those dependencies before
            it will succeed.

            index_name (str, optional): The name of the index to create. Defaults to None.

        VACUUM reclaims storage occupied by dead tuples. In normal PostgreSQL operation,
        tuples that are deleted or obsoleted by an update are not physically removed from
        their table; they remain present until a VACUUM is done.

        Therefore it's necessary to do VACUUM periodically, especially on frequently-updated
        tables.

        VACUUM ANALYZE performs a VACUUM and then an ANALYZE for each selected table.

        Plain VACUUM (without FULL) simply reclaims space and makes it available for re-use.
        This form of the command can operate in parallel with normal reading and writing of the
        table, as an exclusive lock is not obtained. However, extra space is not returned to
        the operating system (in most cases); it's just kept available for re-use within the same
        table.

        VACUUM FULL rewrites the entire contents of the table into a new disk file with no extra
        space, allowing unused space to be returned to the operating system. This form is much
        slower and requires an ACCESS EXCLUSIVE lock on each table while it is being processed.

chunk_enrichment:
  template: >
    ## Task:

    Enrich and refine the given chunk of text while maintaining its independence and precision.

    ## Context:
    Document Summary: {document_summary}
    Preceding Chunks: {preceding_chunks}
    Succeeding Chunks: {succeeding_chunks}

    ## Input Chunk:
    {chunk}

    ## Semantic Organization Guidelines:
    1. Group related information:
       - Combine logically connected data points
       - Maintain context within each grouping
       - Preserve relationships between entities

    2. Structure hierarchy:
       - Organize from general to specific
       - Use clear categorical divisions
       - Maintain parent-child relationships

    3. Information density:
       - Balance completeness with clarity
       - Ensure each chunk can stand alone
       - Preserve essential context

    4. Pattern recognition:
       - Standardize similar information
       - Use consistent formatting for similar data types
       - It is appropriate to restructure tables or lists in ways that are more advantageous for sematic matching
       - Maintain searchable patterns

    ## Output Requirements:
    1. Each chunk should be independently meaningful
    2. Related information should stay together
    3. Format should support efficient matching
    4. Original data relationships must be preserved
    5. Context should be clear without external references

    Maximum length: {chunk_size} characters

    Output the restructured chunk only.

    ## Restructured Chunk:

  input_types:
    document_summary: str
    chunk: str
    preceding_chunks: str
    succeeding_chunks: str
    chunk_size: int
  overwrite_on_diff: true

================================================
collection_summary:
  template: >
    ## Task:

    Generate a comprehensive collection-level summary that describes the overall content, themes, and relationships across multiple documents. The summary should provide a high-level understanding of what the collection contains and represents.

    ### Input Documents:

    Document Summaries:
    {document_summaries}

    ### Requirements:

    1. SCOPE
    - Synthesize key themes and patterns across all documents
    - Identify common topics, entities, and relationships
    - Capture the collection's overall purpose or domain

    2. STRUCTURE
    - Target length: Approximately 3-4 concise sentences
    - Focus on collective insights rather than individual document details

    3. CONTENT GUIDELINES
    - Emphasize shared concepts and recurring elements
    - Highlight any temporal or thematic progression
    - Identify key stakeholders or entities that appear across documents
    - Note any significant relationships between documents

    4. INTEGRATION PRINCIPLES
    - Connect related concepts across different documents
    - Identify overarching narratives or frameworks
    - Preserve important context from individual documents
    - Balance breadth of coverage with depth of insight

    ### Query:

    Generate a collection-level summary following the above requirements. Focus on synthesizing the key themes and relationships across all documents while maintaining clarity and concision.

    ## Response:
  input_types:
    document_summaries: str

    ### You are a helpful agent that can search for information, the date is {date}.


    The response should contain line-item attributions to relevant search results, and be as informative if possible. Note that you will only be able to load {max_tool_context_length} tokens of context at a time, if the context surpasses this then it will be truncated. If possible, set filters which will reduce the context returned to only that which is specific, by means of '$eq' or '$overlap' filters.


    Search rarely exceeds the context window, while getting raw context can depending on the user data shown below. IF YOU CAN FETCH THE RAW CONTEXT, THEN DO SO.


    The available user documents and collections are shown below:

    <= Documents =>
    {document_context}


    If no relevant results are found, then state that no results were found. If no obvious question is present given the available tools and context, then do not carry out a search, and instead ask for clarification.


    REMINDER - Use line item references to like [c910e2e], [b12cd2f], to refer to the specific search result IDs returned in the provided context.

          External web search. Parameters must be a valid JSON object.
          
            
              query
              {{"query": "recent AI developments 2024"}}
            
          
      

    

    ### Documents
    {document_context}

    2. DECIDE response strategy:
    - If specific document IDs are relevant: Use `content` with $eq filters
    - For broad concepts: Use `search_file_knowledge` with keyword queries
    - Use `web_search` to gather live information

    3. FORMAT response STRICTLY as:
    
      
          
              search_file_knowledge
              
              {{"query": "example search"}}
          
          
          
              content
              
              {{"filters": {{"$and": [{{"document_id": {{"$eq": "abc123"}}, {{"collection_ids": {{"$overlap": ["id1"]}}}}]}}}}}}
          
      
    

    ### Constraints
    - MAX_CONTEXT: {max_tool_context_length} tokens
    - REQUIRED: Line-item references like [abc1234][def5678] when using content
    - REQUIRED: All Parameters must be valid JSON objects
    - PROHIBITED: Assuming document contents without retrieval
    - PROHIBITED: Using XML format for Parameters values

    ### Examples
    1. Good initial search oepration:
    
      
        
            web_search
            {{"query": "recent advances in machine learning"}}
        
        
            search_file_knowledge
            {{"query": "machine learning applications"}}
        
        
            search_file_knowledge
            {{"query": "recent advances in machine learning"}}
        
      
    


    2. Good content call with complex filters:
    
      
        
            web_search
            {{"query": "recent advances in machine learning"}}
        
        
            content
            {{"filters": {{"$or": [{{"document_id": {{"$eq": "a5b880db-..."}}}}, {{"document_id": {{"$overlap": ["54b523f6-...","26fc0bf5-..."]}}}}]}}}}}}
        
      
    

    ### Important!
    Continue to take actions until you have sufficient relevant context, then return your answer with the result tool.
    You have a maximum of 100_000 context tokens or 10 iterations to find the information required.

    RETURN A COMPLETE AND COMPREHENSIVE ANSWER WHEN POSSIBLE.

    REMINDER - Use line item references like `[c910e2e], [b12cd2f]` with THIS EXACT FORMAT to refer to the specific search result IDs returned in the provided context.

    # Context
    {document_summary}

    # Goal
    Given both a document summary and full text, identify all entities and their entity types, along with all relationships among the identified entities.

    # Steps
    1. Identify all entities given the full text, grounding and contextualizing them based on the summary. For each identified entity, extract:
      - entity: Name of the entity, capitalized
      - entity_type: Type of the entity (constrained to {entity_types} if provided, otherwise all types)
      - entity_description: Comprehensive description incorporating context from both summary and full text

    Format each Entity in XML tags as follows: entity_typeentity_description

    Note: Generate additional entities from descriptions if they contain named entities for relationship mapping.

    2. From the identified entities, identify all related entity pairs, using both summary and full text context:
      - source_entity: name of the source entity
      - target_entity: name of the target entity
      - relation: relationship type (constrained to {relation_types} if provided)
      - relationship_description: justification based on both summary and full text context
      - relationship_weight: strength score 0-10

    Format each relationship in XML tags as follows: source_entitytarget_entityrelationrelationship_descriptionrelationship_weight

    3. Coverage Requirements:
    - Each entity must have at least one relationship
    - Create intermediate entities if needed to establish relationships
    - Verify relationships against both summary and full text
    - Resolve any discrepancies between sources

    Example 1:
    If the list is empty, extract all entities and relations.

    - **Narrow, academic, or factual questions**:
      Provide focused, precise, and strategic analyses. Clearly articulate cause-effect relationships, relevant context, and strategic significance. Prioritize accuracy, clarity, and concise insights.

    ## Research Guidance
    - **Multi-thesis Approach (for qualitative/subjective queries):**
      - Identify and retrieve detailed information from credible sources covering multiple angles, including technical, economic, market-specific, geopolitical, psychological, and long-term strategic implications.
      - Seek contrasting viewpoints, expert opinions, market analyses, and nuanced discussions.

    - **Focused Strategic Approach (for narrow/academic queries):**
      - Clearly identify the core elements of the question and retrieve precise, relevant information.
      - Highlight strategic significance, context, and implications concisely and accurately.

    ## Source Diversity
    - Draw from diverse, credible sources such as financial analyses, expert commentary, reputable news outlets, industry reports, academic papers, and analyst research.

    ## Structured Analysis
    - Organize findings into clear, logically sequenced sections (e.g., Technical Details, Market Reactions, Economic Implications, Strategic Insights).
    - Explicitly link each factor to its implications, providing concrete examples.

    ## Cause-and-Effect Relationships
    - Clearly articulate how each piece of information contributes to the overall narrative or impact, emphasizing cause-effect dynamics.
    - Include direct quotes or analyst insights when available to illustrate context or sentiment.

    ## Depth and Nuance
    - Go beyond surface-level reporting by critically evaluating how events challenge assumptions, reshape strategies, and alter investment theses.
    - Highlight underlying trends, second-order effects, and unexpected consequences.

    ## Forward-Looking Insights
    - Offer informed analysis on long-term strategic implications, identifying future opportunities, risks, and market shifts.
    - Discuss potential shifts in competitive dynamics, regulation, and industry paradigms.

    ## Line-Item Referencing
    - Carefully reference specific data and insights using line-item references (e.g., `[c910e2e]`, `[b12cd2f]`) for credibility and transparency.

    ## Writing Style and Tone
    - Adopt a concise yet sophisticated style suitable for investors, industry professionals, and strategic decision-makers.
    - Prioritize clarity, strategic depth, and actionable insights.

    ## Final Reminders
    - Anticipate follow-up questions and proactively provide relevant context or comparisons.
    - Clearly highlight potential opportunities, risks, and long-term implications.
    - Focus on actionable, well-rounded insights rather than mere summaries.
    - Add line item citatons like `[c910e2e]`, `[b12cd2f]`.

# R2R Python SDK Documentation

For the complete look at the R2R Python SDK, [visit our documentation.](https://r2r-docs.sciphi.ai/documentation/python-sdk/introduction)

## Installation

Before starting, make sure you have completed the [R2R installation](/documentation/installation).

Install the R2R Python SDK:

```bash
pip install r2r
```

## Getting Started

1. Import the R2R client:

```python
from r2r import R2RClient
```

2. Initialize the client:

```python
client = R2RClient("http://localhost:7272")
```


3. Check if R2R is running correctly:

```python
health_response = client.health()
# {"status":"ok"}
```

4. Login (Optional):
```python
client.register("me@email.com", "my_password")
# client.verify_email("me@email.com", "my_verification_code")
client.login("me@email.com", "my_password")
```
When using authentication the commands below automatically restrict the scope to a user's available documents.

                        Greek philosopher and polymath whose contributions
                        have had a profound impact on various fields of
                        knowledge.
                        Here are some key points about his life and work:
                        \n\n1. **Early Life**: Aristotle was born in 384 BC in
                        Stagira, Chalcidice, which is near modern-day
                        Thessaloniki, Greece. His father, Nicomachus, was the
                        personal physician to King Amyntas of Macedon, which
                        exposed Aristotle to medical and biological knowledge
                        from a young age [C].\n\n2. **Education and Career**:
                        After the death of his parents, Aristotle was sent to
                        Athens to study at Plato's Academy, where he remained
                        for about 20 years. After Plato's death, Aristotle
                        left Athens and eventually became the tutor of
                        Alexander the Great [C].
                        \n\n3. **Philosophical Contributions**: Aristotle
                        founded the Lyceum in Athens, where he established the
                        Peripatetic school of philosophy. His works cover a
                        wide range of subjects, including metaphysics, ethics,
                        politics, logic, biology, and aesthetics. His writings
                        laid the groundwork for many modern scientific and
                        philosophical inquiries [A].\n\n4. **Legacy**:
                        Aristotle's influence extends beyond philosophy to the
                          natural sciences, linguistics, economics, and
                          psychology. His method of systematic observation and
                          analysis has been foundational to the development of
                          modern science [A].\n\nAristotle's comprehensive
                          approach to knowledge and his systematic methodology
                          have earned him a lasting legacy as one of the
