FULLTEXT search + AJAX ?
 

If one wants to make use of fulltext searches, then the minimum of characters that can be given in the search field is 4 characters.

Because an AJAX driven search starts its search at even 1 character, I wanted to ask if this in some way can work with fulltext searches?

The minimum word length is set in the mysql configuration file for the entire server. You could in theory set it down to 1 character, but I'm not sure if there would be negative implications from this. I changed mine from the default of 4 to 3.

Check the number of characters in the input before sending the AJAX request.

Thanx.
