Occasionally, the search isn't great in my opinion. But I've sure found things from the past there. But unless you were personally involved in the discussion (so that you know what to search and look for) I'd assume it is impossible. Too much noise.

I agree about Slack's search - it can be slow too.

(I actually had so much of a problem with this that I built my own enterprise search tool for my Slack, Trello and GDrive, and now I'm productizing it - https://getctx.io )
