Ai powered suggest keyword search

I am trying to find the most searched questions that people may ask about a specific religion, this seems to be hard to pin down. I'm sorting based off topics and things I think people might ask. It would be nice if you could have a feature, run by ai or an algorithm that calculated a likely high quality keyword search feature based off the highest volume searches found within a folder in order to get even better questions, and then, based off the whole folder, come up with a top 100 list of "most asked questions" within a domain.
