Why isn't the search finding certain threads?

Sorry if this is the wrong forum, I couldn't see a bugs or feedback forum.

I've searched avatar a few times and to my surprise it doesn't return the Music, Movies and TV thread, even though there is one: Avatar. On the first occasion I thought there wasn't one, so posted a trailer in the game's Headlines thread, but I've since seen the movie thread when using the New Posts feature and posted in that thread, yet still when I search thread titles for avatar the movie thread doesn't appear in the results. Any ideas why this is?

Just did a standard search from the top navigation bar for "avatar" (All lower case, no quotes) and Pete's thread is the fourth result.
