Requested feature overview description.

Being able to search for a forum or a post under a specific category rather than in the entirity of the forums.

Why would it be useful?

Sometimes you just want the results of a specific forum category, like when you want to know if a bug or idea you are about to write about hasn't been discussed before. Right now, you can't search in that specific category, and seen the fact that "feature" is a rather widely used word, that is problematic. This is only one example.

What part(s) of the site page(s) are affected?

Forum.
