@frosticek no probs
to start you must have access to /etc/mysql/my.cnf via ssh
edit my.cnf
nano /etc/mysql/my.cnf
add this line under [mysqld] place the minimum value you would like to index, i chose 2 characters
ft_min_word_len = 2
now key ctrl and x will give you option to save and y to overwrite then enter
then restart mysql for settings to take effect
service mysql restart
now to re-index
login to mysql
mysql -u yourusername -p
input your password
find your database name
mysql>show databases;
select your database
mysql>use yourdatabasename;
find your table name (most likely oc_t_item_description)
mysql>show tables;
now if your table is oc_t_item_description if not then change your prefix for this next part
mysql>REPAIR TABLE oc_t_item_description QUICK
now to login out of mysql
mysql> quit
now refresh your site and do a search
