That's because "may" is a stopword in MySQL's full-text indexing, by

with 3 on 'May May'.
Not having ever used FTS; I believe you can adjust it to count 3-character

then need re-indexing, if I'm not mistaken.

Hi,
As of Version 4.0.1 you can use the truncation operator * in boolean mode:
select firstname from contacts where match(firstname,lastname) against
('steff*' in boolean mode);
This will match steff , steffa, steffan, steffane, steffans
But of course not "stef" unless you use 'stef*' .
R
full text search is different than pattern match. If
you want to return stef, you have to use pattern
match.
