[digiKam-users] invert Filters selection, or have a "not" operator

[KRODER Gerhard]

Hi,

having a growing tag base now, it would be very helpfull for filtering 
purposes, to have a kind of "not" or "invert selection" 
operator/function avaliable in place. There is a "general 'not'" for 
"Images Without Faces  tags" avaliable, which is helpfull already.  Is 
there a way not known to me? Workarund might be to select every filter 
tag, an deselct desired, but this is already "challenging", having many 
tags.

For example, ther are about 4000 "unknown faces", and i want not to 
see/process those, that already have a tag for place A or/andevent B.  I 
can easyl show all abut "unknown faces", but i can not easily suppress 
(filter out) those i do not want to see (i.e. those with certain tags).

Any idea how to achiev this?

Cheers, Gerhard
