vbulletin search times for different user groups

[ludachris]

Doesn't look like it's working with that hook location. Here's the code I'm using:

PHP Code:

if (is_member_of($vbulletin->userinfo, 5, 7, 10, 11, 106, 108, 107, 109)) 
{ 
     $vbulletin->options['searchfloodtime'] = '1'; 
} 


Should I try a different search hook location?
