Re: Can anyone help speed up this query?
Hi,
Not sure if it is the major contributor to the execution time, but I think there is a significant overhead with each MATCH function and you should try to limit the number of times you call it. For example, instead of
MATCH(column1) AGAINST ('+term1' IN BOOLEAN MODE) OR
MATCH(column2) AGAINST ('+term2' IN BOOLEAN MODE)
I think you can write
MATCH(column1, column2) AGAINST ('term1 term2' IN BOOLEAN MODE)
It seems you are implementing your own ranking scheme. Have you considered whether the ranking scheme provided by NATURAL LANGUAGE MODE would be sufficient for your needs?
