Hi there.
Current maximum keyword length for search is 5 characters, meaning the forum search is completely unusable for all 3 character acronyms which are abundant in the computer lingo, and even 4 character codenames of the video cards (8800, 2900, etc).

Speaking from the experience of running big vBulletin board, I believe the limit could be safely increased to 3 without _any_ performance penalty. Could it be done?
