how do I search for a forum?

I have arrived at Apple Communisties .... and can search individual posts (badly ... an appalling search mechanism) ... or I can eventually see a list of some forums ... but this list seems very poorly organised (by hardware device, or OS with limited sub options etc.)

At this instance I simply want to find the forum dedicated to making Apple Notes work correctly ... but in the past, and in the future, I have wanted to find other forums within this eco system. How can I search for specific forums?

(or how can I see the breadcrumbs for a found post so that I can navigate up and browse from there?)

BTW. This is similar to the posting of questions ... how do I know where to post?
