I want to change the value of ‘ft_min_word_len’=4 to
‘ft_min_word_len’=2 but unknown variable message appears.

Ravi,

According to mysql docs it looks like you have to restart the server and rebuild your fulltext indexes in order to use ft_min_word_len directive.

You’ll like this in 5.1, then:

mysql> SET GLOBAL slow_query_log = 1;
Query OK, 0 rows affected (0.00 sec)

mysql> SET GLOBAL slow_query_log = 0;
Query OK, 0 rows affected (0.00 sec)
