Search Fatal Error

[محروم.كوم]

Seems like I've had this problem in past where certain keyword searches error out, I think it was fixed with some php settings.

When searching for "car covers" only anyone gets the error...

Code:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 35 bytes) in /home/ferrari/public_html/forum/search.php on line 1160

help remind me how I should handle this.

Thank you,
