This query runs very slow. ~40 seconds.
SELECT count(*) as cnt FROM tel1_offices,tel1_phones WHERE (tel1_offices.M_index=tel1_phones.M_index) AND (tel1_offices.Offname LIKE '%a%');
When I change %a% to %aa% it runs more faster.
Whe change to %aaa% script runs ~10 seconds.
How to optimize my DB, that first query will run faster ~10sec?
