php - Boolean search on database with 5 million rows, very slow -


i have script when user searches "apples", there coloumn related searches "shiny apples", , "rotten apples", etc.

problem searches database has 5,600,000 rows , mysql lagging badly.

here code:

$get = mysql_query("select keyword searches match (keyword) against ('".mysql_real_escape_string(preg_replace('#([\s]+)#', '$1', $title))."' in boolean mode) limit 0,15");

this taking long time process , have active website searches getting performed every second, can recommend me tips?

thanks!

you need indexes. have had experiences in past creating indexes got significant performance gain.
