I am looking for upgrade to MySQL 5.0.
Production server has installed 4.1
Testing server has 5.0

SELECT MATCH(keys, text) AGAINST('$morewords') as matched, id, keys, text from table1

Number of $query['matched'] =1 -> 122 in 4.1
Number of $query['matched'] =1 -> 0 in 5.0

Thanks for a clue on what's going on.
