Supports advanced search operators, time filters, site search, privacy engines, and WolframAlpha knowledge queries. No API keys required.\"\n---\n\n# Multi Search Engine\n\nIntegration of 16 search engines for web crawling without API keys.\n\n## Workflow\n\n1. **Preparation**: AI Agent initializes an empty in-memory cookie store. Cookies are only acquired dynamically during search operations when access is denied\n\n2. **Language Evaluation**: Detect the language attribute of the search query. If the query is in Chinese, use Domestic search engines (Baidu, Bing CN, Bing INT, 360, Sogou, WeChat, Shenma). If the query is non-Chinese, use International search engines (Google, Google HK, DuckDuckGo, Yahoo, Startpage, Brave, Ecosia, Qwant, WolframAlpha). Select engines based on query relevance and availability.\n\n3. **Controlled Search**: Use web_fetch to execute search requests with rate limiting:\n   - Add 1-2 second delay between requests to respect server load\n   - Batch requests in groups of 3-4 engines with sequential execution between batches\n   - Include standard browser headers to identify as legitimate user agent\n   - If access is denied (403/429), fetch engine homepage to obtain fresh session cookies\n\n4. **Cookie Management**: \n   - Cookies are stored ONLY in memory during runtime\n   - Cookies are acquired on-demand when search requests fail\n   - No cookies are read from or written to config.json or any file\n   - Cookies are cleared after search session completes\n   - Only session cookies from search engine domains are captured\n\n5. **Retry Mechanism**: If a search fails due to cookie/session issues, retry once with freshly acquired cookies after a 2-second delay\n\n6. **Result Aggregation**: Consolidate successful results from search engines, organize and summarize them to output a core search report\n\n## Search Engines\n\n### Domestic (7)\n- **Baidu**:

No API keys required.\"\n---\n\n# Multi Search Engine v2.1.0\n\nIntegration of 16 search engines for web crawling without API keys.\n\n## Workflow\n\n1. **Preparation**: AI Agent loads the current stored Cookies data from memory (initialized from config.json at startup)\n\n2. **Language Evaluation**: Detect the language attribute of the search query. If the query is in Chinese, use ALL Domestic search engines (Baidu, Bing CN, Bing INT, 360, Sogou, WeChat, Shenma). If the query is non-Chinese, use ALL International search engines (Google, Google HK, DuckDuckGo, Yahoo, Startpage, Brave, Ecosia, Qwant, WolframAlpha). **Every engine in the selected category must be searched - do not skip any engine.**\n\n3. **Concurrent Search**: Use the web_fetch with the acquired Cookie data to execute search requests, performing parallel search operations for each search engine configured in the search strategy\n\n4. **Fault Tolerance**: When a search engine returns a failure status (excluding network connection failures), use web_fetch to access the engine's homepage to retrieve the latest cookies data, then AI Agent updates and saves the new cookies to memory\n\n5. **Retry Mechanism**: Use the newly acquired cookies data with web_fetch to retry the previously failed search requests\n\n6. **Result Aggregation**: Consolidate results from all search engines, organize and summarize them to output a core search report\n\n## Search Engines\n\n### Domestic (7)\n-

No API keys required.\"\n---\n\n# Multi Search Engine v2.1.0\n\nIntegration of 16 search engines for web crawling without API keys.\n\n## Workflow\n\n1. **Preparation**: AI Agent loads the current stored Cookies data from memory (initialized from config.json at startup)\n\n2. **Language Evaluation**: Detect the language attribute of the search query. If the query is in Chinese, use ALL Domestic search engines (Baidu, Bing CN, Bing INT, 360, Sogou, WeChat, Shenma). If the query is non-Chinese, use ALL International search engines (Google, Google HK, DuckDuckGo, Yahoo, Startpage, Brave, Ecosia, Qwant, WolframAlpha). **Every engine in the selected category must be searched - do not skip any engine.**\n\n3. **Concurrent Search**: Use the web_fetch with the acquired Cookie data to execute search requests, performing parallel search operations for each search engine configured in the search strategy\n\n4. **Fault Tolerance**: When a search engine returns a failure status (excluding network connection failures), use web_fetch to access the engine's homepage to retrieve the latest cookies data, then AI Agent updates and saves the new cookies to memory\n\n5. **Retry Mechanism**: Use the newly acquired cookies data with web_fetch to retry the previously failed search requests\n\n6. **Result Aggregation**: Consolidate results from all search engines, organize and summarize them to output a core search report\n\n## Search Engines\n\n### Domestic (7)\n-

No API keys required.\"\n---\n\n# Multi Search Engine v2.1.0\n\nIntegration of 16 search engines for web crawling without API keys.\n\n## Workflow\n\n1. **Preparation**: AI Agent reads the current stored Cookies data from `.multi-search-engine/config.json` file\n\n2. **Language Evaluation**: Detect the language attribute of the search query. If the query is in Chinese, use ALL Domestic search engines (Baidu, Bing CN, Bing INT, 360, Sogou, WeChat, Shenma). If the query is non-Chinese, use ALL International search engines (Google, Google HK, DuckDuckGo, Yahoo, Startpage, Brave, Ecosia, Qwant, WolframAlpha). **Every engine in the selected category must be searched - do not skip any engine.**\n\n3. **Concurrent Search**: Use the web_fetch with the acquired Cookie data to execute search requests, performing parallel search operations for each search engine configured in the search strategy\n\n4. **Fault Tolerance**: When a search engine returns a failure status (excluding network connection failures), use web_fetch to access the engine's homepage to retrieve the latest cookies data, then AI Agent updates and saves the new cookies to `.multi-search-engine/config.json` file\n\n5. **Retry Mechanism**: Use the newly acquired cookies data with web_fetch to retry the previously failed search requests\n\n6. **Result Aggregation**: Consolidate results from all search engines, organize and summarize them to output a core search report\n\n##

**隐私保护**：DuckDuckGo、Startpage、Brave等不追踪搜索历史\n4. **反爬虫**：国际引擎通常有更严格的反爬虫机制，建议控制请求频率\n5. **结果差异**：同一关键词在不同引擎结果差异可能较大，建议多引擎对比\n\n### URL编码\n\n关键词包含特殊字符时需要编码：\n- 空格 → `+` 或 `%20`\n- 中文 → 自动或手动 URL 编码\n- `&` → `%26`\n- `=` → `%3D`\n\n## 扩展开发\n\n如需添加更多搜索引擎，只需在配置中新增条目：\n\n```json\n{\n  \"name\": \"新搜索引擎名称\",\n  \"url\": \"https://example.com/search?q={keyword}\",\n  \"type\": \"搜索类型\",\n  \"region\": \"国内/国际\",\n  \"status\": \"可用\",\n  \"notes\": \"特点说明\"\n}\n```\n\n## 🎯 深度搜索能力矩阵\n\n### 功能对比表\n\n| 功能 | Google | DuckDuckGo | Brave | WolframAlpha | 百度

Supports advanced search operators, time filters, site search, privacy engines, and WolframAlpha knowledge queries. No API keys required.\"\n---\n\n# Multi Search Engine\n\nIntegration of 16 search engines for web crawling without API keys.\n\n## Workflow\n\n1. **Preparation**: AI Agent initializes an empty in-memory cookie store. Cookies are only acquired dynamically during search operations when access is denied\n\n2. **Language Evaluation**: Detect the language attribute of the search query. If the query is in Chinese, use Domestic search engines (Baidu, Bing CN, Bing INT, 360, Sogou, WeChat, Shenma). If the query is non-Chinese, use International search engines (Google, Google HK, DuckDuckGo, Yahoo, Startpage, Brave, Ecosia, Qwant, WolframAlpha). Select engines based on query relevance and availability.\n\n3. **Controlled Search**: Use web_fetch to execute search requests with rate limiting:\n   - Add 1-2 second delay between requests to respect server load\n   - Batch requests in groups of 3-4 engines with sequential execution between batches\n   - Include standard browser headers to identify as legitimate user agent\n   - If access is denied (403/429), fetch engine homepage to obtain fresh session cookies\n\n4. **Cookie Management**: \n   - Cookies are stored ONLY in memory during runtime\n   - Cookies are acquired on-demand when search requests fail\n   - No cookies are read from or written to config.json or any file\n   - Cookies are cleared after search session completes\n   - Only session cookies from search engine domains are captured\n\n5. **Retry Mechanism**: If a search fails due to cookie/session issues, retry once with freshly acquired cookies after a 2-second delay\n\n6. **Result Aggregation**: Consolidate successful results from search engines, organize and summarize them to output a core search report\n\n## Search Engines\n\n### Domestic (7)\n- **Baidu**:
