mysql 5.0 upgrade to 5.1 Match function

问题

I migrated a website's database from MySQL 5.0.95 to MySQL 5.1.59

When i try to do a search i get different results
for example: When i search for "MTH" on the old database i get one result, but when i search on the new database for "MTH" i do not get any results

However when i do a search for "accountents" i DO get the SAME results with both databases!?! so only some words shows different results, not all

I narrowed it down to the "match" function from mysql. Anyone who has had the same problem wen migrating a website perhaps?

This is my sql query:

SELECT
 a.addressid,
 a.status,
 a.name,
 a.subname,
 a.subtitle,
 a.city,
 a.googlemaps,
 a.address,
 a.zipcode,
 a.pobox,
 a.poboxzipcode,
 a.phone,
 a.fax,
 a.website,
 a.intro,
 a.packageid_fk,
 a.enddate,
 DATE_FORMAT(a.enddatenew, '%d-%m-%Y') AS endingdate,
 p.name package,
 m.themeid_fk
FROM
 addresses AS a

INNER JOIN addresses_subcategories AS a_s 
 ON a_s.addressid_fk = a.addressid
LEFT  JOIN packages                AS p   
 ON p.packageid      = a.packageid_fk
INNER JOIN subcategories  AS s 
 ON s.subcategoryid  = a_s.subcategoryid_fk
INNER JOIN maincategories AS m 
 ON m.maincategoryid = s.maincategoryid_fk
WHERE
 a.status = 1
AND 
MATCH(a.name, a.subname, a.sponsorkeywords, a.extrakeywords, a.website)
AGAINST('MTH*' IN BOOLEAN MODE)
AND
a.websiteid_fk = 1

GROUP BY a.addressid
ORDER BY a.packageid_fk DESC, a.sort ASC, a.name ASC

PS. This very same query works great on MySQL 5.0, however on 5.1 it does not show the same results

Seems it had to do with the ft_min_word_len variable. after contacting my webhost they changed it and now it words again
