Wikia needs to do alot of work on wiki search. In theory, it should work roughly on par with Wikipedia, but I think they have diverged the MediaWiki codebase in places they didn't expect to affect search so badly, but it has. They're still untangling it. I have hope that they'll figure it out, but as someone who's followed the topic for years, I don't think it is in the top 5 of their priorities yet.
