No result for words : first, second, third,...

[QUANG NGUYEN]

Hi all !
My table has about 97.000 record and it has a lot of rows that contain words like : first, second, third,... But when I perform a query below:

SELECT name
FROM test_table
WHERE MATCH (name) AGAINST('first');//or "second", "third",...

it returns no result. But when I do this:

SELECT name
FROM test_table
WHERE name like '%first%';

I get results. I don't know why. Can anybody help me !
Thanks
