> SELECT title, content, MATCH(title,content) AGAINST ('searchterm' IN BOOLEAN MODE) AS bool_score, MATCH(title,content) AGAINST ('searchterm') AS nonbool_score FROM search;

excellent this was a good help.

What I did in the end up to speed things up was de-normalize the posts and topics table. It still uses filesort, but I was swayed when you said that "filesort doesn't necessarily mean it wont be used in memory." We will add triggers for the topics and posts tables. Do you know of anything I should look out for with triggers regarding data integrity.
