The simplest is to make sure the branch is not shown for searches. Se http://help.senselogic.se/SiteVision_2_6/indexingSettings.html
But if you would like the content to be searchable but not in this search a hidden search string is required.
Type the following in hidden search string beneath the tab Advanced in the search portlet:
AND NOT path:id-nummer
The Id number can be reached for each page/archive/folder by choosing Properties -> General -> Page information ->Id.
- Id for an archive always begins with 3
- Id for web pages always begins with 4
- Id for a folder always begins with 19
