Hi,
The slow queries are those like...
SELECT id FROM table WHERE field like '%text%' AND ok=1 AND type=1
where table have about 20.000 records and field is a text field.
I need to find ALL the records that have "text", even if text is "a" i have
to find all the records that have one "a".
Many of that querys take 16 or 20 seconds.
what do you think?
