Read the manual, the most frequent words are stopped in index.

I think if you take a look at the MySQL docs on FULLTEXT it'll explain it alot

Hi,
Thanks a lot, the select is much faster now. But I find something
weird, it return nothing when match against the string "the", which
return 255568 entries when select "% the %", is it possible mysql
does not indexed some words for some reason?
select count(*) from Books where match Title

Try this:
SELECT count(*) FROM Books WHERE MATCH Title AGAINST 'cisco'
We use a FULLTEXT index search in a couple of our table for business referral

Hi,
Here is the fulltext index I add:
CREATE TABLE Books (
isbn char(10) NOT NULL default '',
Title char(255) NOT NULL default '',
FULLTEXT KEY full_title (Title)
) TYPE=MyISAM;
select count(*) from Books --> 2028971
select count(*) from Books where Title like "% cisco %"

Why don't use FULLTEXT index ? This select doesn't use normal index so
you have a sort of linear search
