Google搜索结果限制 [英] Google search results limits

问题描述

我尝试在Google搜索引擎中搜索星期天"一词.

I tried to search in google search engine the word "sunday".

结果总数为1.390.000.000.但是，我只能看到前420条结果，直到42页结果为止.

The total number of results is 1.390.000.000. However I can see only the first 420 results, until 42 page of results.

有什么办法获取Google搜索的所有结果?

Is there any way to take all the results of google search?

推荐答案

谷歌的这一功能"以及其他搜索引擎也适用于网络界面.第一页要求的匹配数不会反映在实际返回的结果数中.

This 'feature' of google - and other search engines - applies to the web interface too. The claimed number of matches on the first page is not reflected in the actual number of results returned.

例如，如果您，它将在首页上声明几百万个结果，但是如果您转到第3页(每页100个结果)，将估算值修订"为200-300个结果.

For example, if you search Google for "Systematic Literature Review" it will claim a few milion results on the first page, but if you go to page 3 (at 100 results/page) it will 'revise' the estimate to 200-300 results.

这在初始估计中似乎太高了，但是可能是过滤大型数据集的问题，并且可能是可以原谅的.但是，对于该主题返回的实际结果肯定太少了. Bing和DuckDuckGo相似. Google学术搜索声称获得11k左右的结果，但如果尝试超过1000，则会返回服务器错误.

This seems too high in the initial estimate but may be a problem with filtering large datasets and is possibly forgivable. However it is definitely too small a number of actual results returned for this topic. Bing and DuckDuckGo are similar. Google Scholar claims 11k or so results but returns a server error if you try going beyond 1000.

推测:这可能是为了鼓励人们更改搜索条件，而不是返回大量结果，然后将结果以编程方式在本地进行过滤(这是我想做的！).

Speculating: this might be in order to encourage people to change their search terms, rather than return a huge number of results that are then filtered programmatically locally (which is what I would like to do!).

恐怕这不是获得更多结果的答案，但这是一种解释，问题不是库，而是搜索引擎.

This isn't an answer to getting more results I'm afraid, but it is an explanation that the problem is not the library, it's the search engine(s).
