6 rows in set (0.00 sec)

Создана она была вот так:

mysql> CREATE TABLE articles (id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY, title VARCHAR(200), body TEXT,FULLTEXT (title,body));

И вот я ищу там 'database'
mysql> SELECT * FROM articles WHERE MATCH (title,body) AGAINST ('database');
+----+-------------------+------------------------------------------+
| id | title | body |

2 rows in set (0.00 sec)

Ну чтож - вполне успешно.
Но вот я ищу там 'this':
mysql> SELECT * FROM articles WHERE MATCH (title,body) AGAINST ('this');
Empty set (0.00 sec)

И какого, спрашивается, фига? Там же есть слово this - вон оно торчит..

Вот. Где я тормоз?
