Wikia search launched today. As the name indicates the Jimmy Wales, founder of Wikipedia is behind this new search egine.

Wikia's search engine concept is that of trusted user feedback from a community of users acting together in an open, transparent, public way. Of course, before we start, we have no user feedback data. So the results are pretty bad. But we expect them to improve rapidly in coming weeks, so please bookmark the site and return often.
Right now, the most important thing you can do is help with the "miniarticles" that appear at the top of popular search terms. These will vary in purpose according to the circumstance, but the primary uses will be.
