Well, first of all, MySQL 5 does use more than one index, although I'm not sure it can do this with a full text index. http://dev.mysql.com/doc/refman/5.0/en/index-merge-optimization.html Also, there's a lot of room between a full table scan and using every index. Using any index in a way that allows the query to be satisfied without scanning every single row should be enough to make the count query better. - Perrin -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
