Search function only for special member group

Hi guys,

i hope you can help me with a problem I couldn't find the solution here. I tried quite a few things but nothing worked.

is it  possible to allow only one membership group to search and do you have any idea how to realize?

I already tried "Hide custom pages from non-members" for the search pages

I think the solution is close in this code by DM...

if ($sPageName == 'YOURPAGE' && !isMember()){
$oSysTemplate->displayAccessDenied ();

}else{
