multi-search-engine is a Claude Code skill that builds no-API-key search URLs across 17 engines for developers who need multi-engine web research with advanced operators and privacy options.
About
multi-search-engine (v2.0.1) from family3253/skill integrates 17 search engines—8 Chinese and 9 global—into one agent-facing reference for web crawling without API keys. The skill constructs direct query URLs for Google, Baidu, Bing, DuckDuckGo, Brave, Startpage, Qwant, WolframAlpha, and others, supporting operators such as site:, filetype:, exact quotes, exclusions, OR logic, and time filters from past hour to past year. DuckDuckGo Bangs shortcuts like !gh for GitHub and !so for Stack Overflow accelerate targeted lookups. Developers use multi-search-engine with web_fetch against prebuilt URLs for cross-engine comparison, academic PDF discovery, and privacy-focused searches. The skill documents engine-specific URL patterns in config.json and reference guides rather than calling proprietary search APIs.

🔐 隐私保护最佳实践
搜索引擎隐私级别
| 引擎 | 追踪级别 | 数据保留 | 加密 | 推荐场景 |
|---|---|---|---|---|
| DuckDuckGo | 无追踪 | 无保留 | 是 | 日常隐私搜索 |
| Startpage | 无追踪 | 无保留 | 是 | 需要Google结果但保护隐私 |
| Brave | 无追踪 | 无保留 | 是 | 独立索引，无偏见 |
| Qwant | 无追踪 | 无保留 | 是 | 欧盟合规要求 |
| 高度追踪 | 长期保留 | 是 | 需要个性化结果 | |
| Bing | 中度追踪 | 长期保留 | 是 | 微软服务集成 |
隐私搜索建议
1. 日常使用: DuckDuckGo 或 Brave 2. 需要Google结果但保护隐私: Startpage 3. 学术研究: Google Scholar（学术用途追踪较少） 4. 敏感查询: 使用Tor浏览器 + DuckDuckGo onion服务 5. 跨设备同步: 避免登录搜索引擎账户

FAQ
How many search engines does multi-search-engine cover?
multi-search-engine v2.0.1 integrates 17 search engines, split between 8 Chinese and 9 global options. The skill builds direct query URLs for each engine so agents can fetch results with web_fetch and no API credentials.
Does multi-search-engine require search API keys?
multi-search-engine requires no API keys because it constructs engine-specific search URLs with encoded keywords and operators. Agents execute those URLs via web_fetch or browser tools to retrieve HTML result pages directly.
