Multi Search Engine

Integration of 16 search engines for web crawling without API keys.

Workflow

1. Preparation: AI Agent initializes an empty in-memory cookie store. Cookies are only acquired dynamically during search operations when access is denied

2. 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.

3. Controlled Search: Use web_fetch to execute search requests with rate limiting: - Add 1-2 second delay between requests to respect server load - Batch requests in groups of 3-4 engines with sequential execution between batches - Include standard browser headers to identify as legitimate user agent - If access is denied (403/429), fetch engine homepage to obtain fresh session cookies

4. Cookie Management: - Cookies are stored ONLY in memory during runtime - Cookies are acquired on-demand when search requests fail - No cookies are read from or written to config.json or any file - Cookies are cleared after search session completes - Only session cookies from search engine domains are captured

5. Retry Mechanism: If a search fails due to cookie/session issues, retry once with freshly acquired cookies after a 2-second delay

6. Result Aggregation: Consolidate successful results from search engines, organize and summarize them to output a core search report

Security & Privacy Notice

Cookie Handling

Purpose: Cookies are used ONLY to maintain search session state when access is denied (403/429 errors)

Storage: Cookies are kept STRICTLY in memory during runtime - NEVER persisted to disk or config files

Acquisition: Cookies are acquired on-demand from search engine homepages only when search requests fail

Scope: Only session cookies from the specific search engine domain are captured

Lifecycle: Cookies are cleared immediately after the search session completes

No Pre-configuration: No cookies are loaded from config.json or any external file at startup

No API Keys: This tool uses standard web search URLs, no authentication required

Crawling Ethics

Rate Limiting: Implement reasonable delays between requests (recommend 1-2 seconds)

Respect robots.txt: Honor search engine crawling policies

Terms of Service: Users are responsible for complying with search engine ToS

Purpose: Designed for legitimate search aggregation, not mass data scraping

Data Handling

No Personal Data: Tool does not collect or transmit user personal information

Local Execution: All operations run locally, no external data transmission

Session Isolation: Cookies are session-specific and cleared after use
