Topic search button

The forum needs a topic search, that way you can look for a specific type of topic. This would save on people creating multiples of the same post. I'm fairly new here, so unless I'm blind and there actually is one, please point me in the right direction.

I support this suggestion – search for threads, and posts too. A search within a thread would be also useful (like in vBulletin or MyBB). Btw. forum search has been suggested before: http://www.maiotaku.com/mytopics/6012/mytopics/10533
