My sql full text search does not index words shorter than four letters. You would have to recompile my sql to fix this, which wouldnt be doable anyway if eu forum ever moved back to shared hosting. You could use LIKE assuming its not hideously slow (probably would be on a forum this big), recompile my sql (which would mean never being able to use shared hosting), create your own indexing system (php scripts exist already to do this), or simply make the forum search refuse short words.
