Not too familar with FULLTEXT, however with LIKE, you will get one result with the query...right?
SELECT
Search, count(*) AS cnt
from querylist
WHERE search LIKE '%expression%'
So you won't neccessarily need to order cnt in this situation, unless you group by some other field that you're not using LIKE on I suppose:
SELECT
Search, count(*) AS cnt
from querylist
WHERE search2 LIKE '%expression%'
GROUP BY Search
ORDER BY cnt DESC
