i can tell you know this already, but i'm gonna put it in here anyway cause someone else may find it helpful and it's related to this thread...
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.
