Technical Support Question on "Search" Function

Sorry, maybe it's just my computer, but in the "search" function when I put some certain words (not all words), let's say "Asian" it come up like this

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 35 bytes) in /home/httpd/vhosts/terbca/httpdocs/vbulletin/search.php on line 1035


Why?
 
It's an issue with the php memory size set too low on the Terb web server php script. There is nothing the user can do to fix it. The System admin has to change the parms..

SYSTEM ADMIN:
Add a line like this to the server’s php.ini file:

memory_limit = 64M

Or change the PHP search script :

ini_set("memory_limit","64M");

Note: If this doesn’t work, SYSADMIN to keep increasing the memory limit until the script works.
