✨ MindSearch: Mimicking Human Minds Elicits Deep AI Searcher

📅 Changelog

• 2024/11/05: 🥳 MindSearch is now deployed on Puyu! 👉 Try it 👈
  • Refactored the agent module based on Lagent v0.5 for better performance in concurrency.
  • Improved the UI to embody the simultaneous multi-query search.

⚽️ Build Your Own MindSearch

Step1: Dependencies Installation

git clone https://github.com/InternLM/MindSearch
cd MindSearch
pip install -r requirements.txt

Step2: Setup Environment Variables

Before setting up the API, you need to configure environment variables. Rename the .env.example file to .env and fill in the required values.

mv .env.example .env
# Open .env and add your keys and model configurations

Step3: Setup MindSearch API

Setup FastAPI Server.

python -m mindsearch.app --lang en --model_format internlm_server --search_engine DuckDuckGoSearch --asy 

• --lang: language of the model, en for English and cn for Chinese.

• --model_format: format of the model.

  • internlm_server for InternLM2.5-7b-chat with local server. (InternLM2.5-7b-chat has been better optimized for Chinese.)
  • gpt4 for GPT4.
    if you want to use other models, please modify models

• --search_engine: Search engine.

  • DuckDuckGoSearch for search engine for DuckDuckGo.
  • BingSearch for Bing search engine.
  • BraveSearch for Brave search web api engine.
  • GoogleSearch for Google Serper web search api engine.
  • TencentSearch for Tencent search api engine.

  Please set your Web Search engine API key as the WEB_SEARCH_API_KEY environment variable unless you are using DuckDuckGo, or TencentSearch that requires secret id as TENCENT_SEARCH_SECRET_ID and secret key as TENCENT_SEARCH_SECRET_KEY.

• --asy: deploy asynchronous agents.

Step4: Setup MindSearch Frontend

Providing following frontend interfaces,

• React

First configurate the backend URL for Vite proxy.

HOST="127.0.0.1"  # modify as you need
PORT=8002
sed -i -r "s/target:\s*\"\"/target: \"${HOST}:${PORT}\"/" frontend/React/vite.config.ts

# Install Node.js and npm
# for Ubuntu
sudo apt install nodejs npm

# for windows
# download from https://nodejs.org/zh-cn/download/prebuilt-installer

# Install dependencies

cd frontend/React
npm install
npm start

Details can be found in React

• Gradio

python frontend/mindsearch_gradio.py

• Streamlit

streamlit run frontend/mindsearch_streamlit.py

🌐 Change Web Search API

To use a different type of web search API, modify the searcher_type attribute in the searcher_cfg located in mindsearch/agent/__init__.py. Currently supported web search APIs include:

• GoogleSearch
• DuckDuckGoSearch
• BraveSearch
• BingSearch
• TencentSearch

For example, to change to the Brave Search API, you would configure it as follows:

BingBrowser(
    searcher_type='BraveSearch',
    topk=2,
    api_key=os.environ.get('BRAVE_API_KEY', 'YOUR BRAVE API')
)

🐞 Using the Backend Without Frontend

For users who prefer to interact with the backend directly, use the backend_example.py script. This script demonstrates how to send a query to the backend and process the response.

python backend_example.py

Make sure you have set up the environment variables and the backend is running before executing the script.

🐞 Debug Locally

python -m mindsearch.terminal
