Forum:Answers wikis clogging with duplicate questions

Not sure if this is the place to ask this, since I hardly come here. I don't how if other answers wikis are experiencing this, but over at Avatar Answers Wiki, there are loads of users, both registered and unregistered (though the vast majority who asks questions is unregistered), who clog the wiki with duplicate questions. Because a single different letter creates an entirely new question article, asking something which was already asked and answered. In a single day, me and other users have answered the same question over 10 times in two hours. I can't say for sure, but I think it's because the "ask a question" field stands out much more the "search this Q&A site" one, much smaller, and to the left. I think most users don't even see it, and since a note was added to the main page, most likely some ignore it, and just plain add the many duplicate and already answered questions. It creates undue work and it's frustrating for regular users. Is there a way to change the functionality, or possibly swap the two fields? Are there other answers wikis suffering from this?

 * It happens on all Answers wikis. The best thing to do is to redirect the ones with smaller or no answers to the biggest, more detailed answer. 07:51, June 26, 2010 (UTC)
 * Google seems to have a pretty good algorithm for figuring out similar searches and guessing about misspelings, but I suspect they spent more money on that one project than Wikia makes in a year. -- Fandyllic  (talk &middot; contr) 8:39 PM PST 26 Jun 2010
