The search function couldn't find any results, so I changed it to work for me.
In functions line 374, I updated it to this:
//$q = 'MATCH(`url`,`name`,`description`) AGAINST("'.mysql_safe($search).'")';
//$query = 'SELECT * FROM '.$settings['links_table'].' WHERE `approved`="true" and '.$q;
$q = mysql_safe($search);
$query = 'SELECT * , MATCH (`url` , `name` , `description`) AGAINST("%'.$q.'%") AS list FROM links WHERE `approved`="true"';

With most mysql configurations, you will need at 3-4 items in your links
table for the search to work. I want to say that the original query was
more efficient than your modified query but I cannot say that with 100%
certainty.
