If it's anything like phpBB, there should be a setting in the Admin control panel that's allows changing the search indexing minimum. It's quite literally a one-click change in phpBB. It has a lot more to do with the database (MySQL, etc.), than it does PHP.

You can't wildcard something that the search mechanism hasn't indexed at all. As far as search is concerned, words less than the minimum number of characters don't exist.
