This isn’t a critical feature, so it obviously wouldn’t be a priority at all at the moment, but you should seriously consider putting a “discussion search” feature somewhere on the late timeline. This was in Google for years and was, arguably, the most useful search feature for a lot of topics. Google removed it as part of their efforts to keep people “within the Google network” i.e. on pages with Google ad tracking.
It was just a feature that only included results from forums, from Reddit to obscure topic-specific forums. Pretty much any site running forum software was included. Essentially, you could use it to find actual experts/enthusiasts discussing a topic rather than getting 3 pages of “here’s an AI generated top-10-list blog page with Amazon links and Google ads.”
