I assume you mean the floodcheck to prevent more than 1 post/search within X seconds.

Taken from search.php:

PHP Code:

        if (TIMENOW - $prevsearch['dateline'] < $vboptions['searchfloodtime'] AND $vboptions['searchfloodtime'] != 0 AND !($permissions['adminpermissions'] & CANCONTROLPANEL) AND !can_moderate())
        {
            eval(print_standard_error('error_searchfloodcheck'));
        }
