In the Design module
you will find the additional control
Search.
With this control, users can search in the entire portal. The search terms
are entered in the search field. The search is started by pressing
the Enter key or clicking on the "Search" button
(to the right of the field).
The place where a hit was found will be
loaded in the main window by clicking on a search result link.
The search will only output the results
for which the logged-in user has sufficient
access permissions.
