I am testing the search feature on my XF forum and it said too few characters (3). So I went in and changed it to '3' in the 'Search Options' section in admin.
Now it does not return any results.
Then I read this in the search options section:
'This is the minimum length of a word that can be searched by the index. With the default search system, this should correspond with the MySQL full text minimum word length (normally 4).'
So do I need to change something in the MySQL to make this work?
