Modify minimum search length of MySQL
13 January 2013
MySQL by default requires minimum of 4 alphabets to perform a search.
Here is a way to modify the minimum number on CentOS:
# mysql -u root
# nano /etc/my.cnf
add the below line and save it, the number indicate the minimum length for the search, here we put 3.
# service mysqld restart
rebuild the fulltext index of sql and it should work.
