boolean filter criteria for select or hide pictures

Boolean operators like "NOT","AND","OR" for key word search is a very important feature for me. Filtering in two levels could be nice too:

while browsing and searching with friends through my pictures I whish to have a pre filter to hide for example private pictures:

First level to select pictures to hide:
example filter criteria key words: NOT "naked","privat"

Second level to search for pictures:
example search for pictures with key words "beach","holiday"

My first message was in German, because my entry window for discussion board for XnView is also in German - sorry !
