Filtering search query results using a genetic algorithm, any examples?

Question

Search engines

Good afternoon. The task is to figure out how to organize the filtering of search results using a genetic algorithm (you can even without genetics), let's limit ourselves to at least the google site. Those. it is necessary to make a kind of extension for the browser that will discard the same or text-similar search results, as well as search by known keywords (tags), it is even possible to throw older (original) articles up by publication date (as if showing the source of the data) .
So, are there any directly approximate solutions?
Thanks for the replies in advance)
