Not really, the query took 4-5 seconds. The query runs through 13910 rows
according to explain, that isnt alot is it?
SELECT COUNT(*) antal,ad.ad_id FROM ad
INNER JOIN tag_ad_map tm ON tm.ad_id=ad.ad_id
WHERE
tm.tag_id IN (99, 10807, 20728, 21, 135)
AND ad.is_removed = 0 AND ad.is_active=1 AND
I have a query that runs very slow and using Using temporary; Using
filesort. Is there a way to avoid them using current table structure?
Goal with the query is to find ads (ad_id) that have tags (tag_id) connected
to them, order by "antal" is used to get the most relevant first. ( the one
that con
ort_buffer_size by using the command
show global variables like 'sort%';

I need help to optimize this following query. It runs very slow and I cant
find any direct errors in it.
SELECT
1 * t1.termfreq as viktatantal,
t1.tag, t1.url FROM tag_keys t1
LEFT JOIN tag_ad_map tm1 ON t1.id = tm1.tag_id
LEFT JOIN tag_ad_map tm2 ON tm1.ad_id = tm2.ad_id
LEFT JOIN tag_keys t2 ON t
