Search error

Here's a strange search problem:

Do a search for the two words work ram

and you get the error:

Fatal error: Allowed memory size of 25165824 bytes exhausted (tried to allocate 35 bytes) in /home/www/neo-geo/forums/search.php on line 1062

Searches with other words are okay.

Either the word "work" or "ram" is getting too many hits and overloading the search engine.
