My usual use case is to search HN comments. Problem is that there doesn't seem to be a way to specify comments on the bang search itself, so you have to toggle the results page option, or click "search for comments" to get the 57 (at this writing) comment hits:
I really wish the bang would default to comment search, as it's a much broader search target. Posts are limited to 80 characters, comments to rather more than that (there is a max comment length, and I've hit it, but it's fairly generous). So your odds of matching term(s) in a comment are higher than for posts.
