if (is_member_of($vbulletin->userinfo, 2, 3, 4))
{
    $vbulletin->options['searchfloodtime'] = 0;
}

In global_complete should work for 3x series


Actually played around with it

use global_setup_complete

and your code would look as follows (confirmed working)

if (is_member_of($vbulletin->userinfo, 2, 3, 4))
{
    $vbulletin->options['searchfloodtime'] = "120";
}
