Improve Integration Docs Discovery

Feedback on searching for an integration such as "S3 integration settings" does not return any s3 pages at all. This is a similar problem with other integrations as well.

This is kind of the problem we've run into in the past in that a search query like this goes into semantic search territory, which is beyond the scope of our current search. What would the user be expecting to find for such a search? There are several different integrations for S3 (S3Queue, S3 table engine, S3, S3 disk storage for OSS users etc) and settings for everything are on the settings page. We don't split them by integration at all currently. With the current search we could make a new section for S3 integration settings specifically, but then we also need to think about Kafka integration settings, MongoDB integration settings etc which gets tricky.

Searching "S3 integration settings" on Ask AI actually returns pretty good results imo and groups them by integration type in the answer which I feel is probably more what the user is looking for. The more interesting question for me is how we can provide both a semantic and lexical search experience and make it seamless for users?

We have the ability to integrate the Ask AI directly into the search as far as I know. Maybe this is something we should explore.
