Idea for search engines

You know, I had a thought. That any search engine has a cache - we know. At the same time, we know about Wayback Machine , which allows us to go back in time and look at a particular site.

And why shouldn't search engines, adding information to the cache, label it with a date? It is clear that this date will be slightly different from the release date of information (the scale of the Internet affects), but still, it is convenient! The user can search for the word "vulnerability" on the Internet of the 2000 sample, for example.

At the same time, the results can also be filtered by "freshness." Maybe I want to look for the word "fire fox" only on those sites where it appeared after 2003.

As a result, we get a web archive and a search engine.

Comments are welcome :)
