    RAG with LlmaIndex x Desearch

    LlamaIndex is a framework for building LLM applications powered by structured data. In this guide, we’ll use Desearch’s LlamaIndex integration to:

    This guide demonstrates how to enhance a LlamaIndex agent with Desearch’s web search capabilities.

    1. Specify Desearch’s Search and Retrieve Tool as a LlamaIndex retriever
    2. Set up an OpenAI Agent that uses this tool in its response generation

    🚀 Quick Start

    1. Install Required Packages

    bash
    pip install llama-index llama-index-core llama-index-desearch

    2. Instantiate the Desearch Tool

    * Also ensure API keys are initialized properly. The following code uses the DESEARCH_API_KEY as the relevant environment variable name.

    python
    from llama_index_desearch.tools import DesearchToolSpec import os desearch_tool = DesearchToolSpec( api_key=os.environ["DESEARCH_API_KEY"], )

    3. Select Desearch Methods to Use

    For this example, we are only interested in passing the ai_search_tool method to our agent, so we specify this using the .to_tool_listLlamaIndex method.

    python
    search_and_retrieves_tool = desearch_tool.to_tool_list( spec_functions=["ai_search_tool"] )

    4. Set Up the OpenAI Agent

    Set up the OpenAIAgent, passing the filtered down toolset from above.

    python
    from llama_index.agent.openai import OpenAIAgent agent = OpenAIAgent.from_tools( search_and_retrieves_tool, verbose=True, )

    We can then use the chat method to interact with the agent.

    python
    agent.chat( "Can you summarize the news from the last month related to the US stock market?" )

    🛠️ Desearch Tool Functions

    • ai_search_tool: The Desearch API allows you to perform AI-powered web searches, gathering relevant information from multiple sources, including web pages, research papers, and social media discussions.
    • twitter_search_tool: The X Search API enables users to retrieve relevant links and tweets based on specified search queries without utilizing AI-driven models. It analyzes links from X posts that align with the provided search criteria.
    • web_search_tool: This API allows users to search for any information on the web. This replicates a typical search engine experience, where users can search for any information they need.
