## About Search Engine

### How to use Serper Search?
To use Serper as your search engine, you need to:
1. Get your API key from [Serper](https://serper.dev/)
2. Set `SEARCH_API=serper` in your `.env` file
3. Set `SERPER_API_KEY=your_api_key` in your `.env` file

DeerFlow allows you to control which domains are included or excluded in Tavily search results through the configuration file. This helps improve search result quality and reduce hallucinations by focusing on trusted sources.
