[pmwiki-users] Problem with $SearchPatterns

["Kai Bühler (celanio GmbH)"]

Hello,
I want to allow searches in 4 groups and exclude all groups starting
with "P".

So I tried:

$SearchPatterns['default'][] ='/^De\\./';
$SearchPatterns['default'][] ='/^CRM\\./';
$SearchPatterns['default'][] ='/^FAQ\\./';
$SearchPatterns['default'][] ='/^Glossar\\./';
$SearchPatterns['default'][] ='!^P\.!';

(Groups are "De", "CRM", "FAQ" and "Glossar", and others starting with
P, e.g. P0034, P0056.

But everytime I try this config it finds nothing anymore ;-( If I remove
CRM, FAQ and Glossar it works and finds results from the "De" Group.
Where's my mistake?

Kai.
