[quote=Mahz]What are yall's main uses for a search feature, like what are the kinds of searches you find yourself doing/wanting the most? I'd like to prioritize the features yall want and perhaps yall have use-cases I haven't thought of.[/quote]
I have found myself searching where exactly something was addressed in a specific thread quite often - so I'd second "search thread" (or even the IC/OoC/CSs os a thread) would be useful. And similarly searching by boards. Whatever lets one narrow a search down and not get hundreds of matches when they already roughly know where what they're looking for is.

(Speaking of which, you might want to stop users from searching from silly things like empty strings and single characters. I am mostly certain yo already thought of that, but I thought I'd mention it just in case. I've seen sites with massive databases designed by people who got paid for specifically that which still let you select and return the entire database by entering either nothing or a wildcard.)
