google-api - Google API 返回的结果与网站不同

Question

当我在 google.com 上进行特定于站点的搜索时:

site:http://one-month-of-chat-logs.github.io security

我得到 12 个结果。我注册了一个自定义搜索引擎 ( cx: 015271449006306103053:mz6wkimeenc ) 和 API key ，当我运行相同的搜索时，我只得到 3 个结果:

$ curl 'https://www.googleapis.com/customsearch/v1?key=$MY_API_KEY&cx=015271449006306103053%3Amz6wkimeenc&q=security'

为什么结果不同？我的 API 请求实际上查询的内容与我在 google.com 上执行的搜索不同吗？

your results are unlikely to match those returned by Google Web Search, for several reasons:

1. Even if a custom search engine is configured to search the entire web, it’s designed to emphasize results from your own sites.
2. Your custom search engine doesn’t include Google Web Search features such as Oneboxes, real-time results, universal search, social feaures, or personalized results.
3. If your custom search engine includes more than ten sites, the results may be from a subset of our index and may differ from the results of a 'site:' search on Google.com.
