There is a lot of bugs fixed in full-test search in 4.0.2:

MySQL doesn't use indexes in this case, because search word begins
with wildcard. MySQL will use indexes in the following statement:
SELECT * FROM table WHERE column LIKE "text%";
It will look for all words that >=text and <texu. for more details
how MySQL uses indexes look at:
