[pmwiki-users] protecting private groups from search

[Stephan Schildberg]

Hello,

I am about to protect private groups from being found through your nice search engine, using pmwiki-2.1.beta28 .
It is protected with a password from prying eyes, but pages, their containing groups and content still can be spotted.

The advice from: http://www.pmwiki.org/wiki/Cookbook/SearchPatterns

Remove the Private group from searches, by adding:

$SearchPatterns['default'][] = '!^Private\.!';
$SearchPatterns['all'][] = '!^Private\.!';
$SearchPatterns['normal'][] = '!^Private\.!';

gives me not the desired result, nothing visible to me happens.
In my opinion this is so important, that I would rather expect the solution in the core documentation.
What I did miss to make some goups close as possible?
Would you please be so kind to give me a hint?

Stephan.
