Multi Search Engine

是什么

把 17 个中外搜索引擎（百度 / 搜狗 / 微信 / Google / Bing / DuckDuckGo / WolframAlpha 等）做成一个"无需 API Key 的并行抓取入口"，帮你在跨境市场调研、隐私敏感检索、知识计算这类场景里同时拿到中文 + 国际 + 隐私三类信源的原始结果。

怎么用

1. 想清楚检索意图属于哪一类（行业市场 / 政策法规 / 学术 / 隐私敏感 / 数学计算），决定要不要全引擎并行。
2. 用 web_fetch 直接拼搜索 URL，国内信源用百度 + 搜狗微信，国际用 Google + DuckDuckGo + Brave。
3. 善用高级算子：site: 限定站内、filetype:pdf 找报告、"" 精确匹配、tbs=qdr:w 限定一周内的内容。
4. 隐私敏感场景优先 DuckDuckGo + Startpage + Brave + Qwant；数字 / 单位换算 / 股价直接走 WolframAlpha。
5. 并行结果记得做去重和交叉验证，不同引擎对同一关键词的排序差异本身就是信号。
