Multiple table search with MySQL & PHP

[DarkRanger]

Does anybody know of some code/script for searching multiple tables/columns in one go. I wrote something, but it's 400 lines odd and with 14000 records to search, it takes way to long (20 - 30 seconds) or times out. Any help will be appreciated.

I'm assuming you are using JOIN and multiple WHERE,AND,OR or possible LIKE, MATCH mysql select statements.

 

To speed the queries up you can create indexes on any WHERE,AND,OR values

http://dev.mysql.com/doc/refman/5.6/en/create-index.html

 

You can view the slow query log to find your bottlenecks

http://dev.mysql.com/doc/refman/5.6/en/slow-query-log.html

 

It does matter the order in which you place these, try EXPLAIN, SHOW STATUS, and SHOW PROCESSLIST

http://dev.mysql.com/doc/refman/5.6/en/explain.html

http://dev.mysql.com/doc/refman/5.6/en/show-status.html

http://dev.mysql.com/doc/refman/5.6/en/show-processlist.html

 

Look into memcache to lessen the queries by caching.

http://memcached.org/

or

http://php.net/manual/en/book.memcache.php

 

If none of the above helps you (which they should), or to get quicker responses to queries, minimize results and only fetch data you need to.

To show the solutions can help:

That's a multiple search sifting through a million plus posts for the correct content in multiple columns, pages will get cached and also is on one of my home computers (single core cpu and run it hard) on a residential line. The thumbs are live loading.
