Visitors - Disallow searching

I have my dolphin set so that visitors do not have any privileges. Even though I took out "make search" (along with everything else), I can still anonymously go to the search page, click search, and results will populate. It doesn't let me view profiles, which is a good thing. But I don't want even searching to be possible unless you are logged into the website.

Any ideas?

add this code to search.php

$logged['member'] = member_auth( 0 );

before this code check_logged();

visitors and members who are not logged in will be redirected to login form

---------

code will be like this

$_page['name_index'] = 4;
$_page['css_name']   = 'search.css';

$logged['member'] = member_auth( 0 );
check_logged();
