three letter searches didn't work for me even when the threads software was set to do three character searches. until i found out this from Rick:
==============
I think that may be a limitation on your host. Some hosts have the minimum search index at 4 characters for MySQL, so it won't find any results on 3 character searches. You'll want to contact your host and check what they have for the minimum character length for MySQL full text indexing.
=============
I did some digging and found that the variable is:
ft_min_word_len
by default, it was set to 4. I lowered this to 3 and everything works fine on 3 character searches.
