Search for pictures in sub-file structure

Hi,
I have a database running with approx 20k pictures.

The physical file structure is
Digikam(root)
— Afrika
——trip 1
——trip 2
— Europa
—— trip 1
—— trip 2
etcpp see picture above.

I am trying to start with a substructure i.e. ‘Afrika’ to find all ‘Non tagged’ pictures.

If I use the ADVANCED SEARCH as explained in

it seems I cannot search only ‘Afrika’ by checking the box and selecting additional search criteria.
Only if I select every subfolder and all picture containing folders (i.e. sub-sub-structures) manually , the whole file structure placed in ‘Afrika’ will be considered.

I cannot believe, that there is a restriction like this and I hope this is more a lack of knowledge on my side.

Can someone please give a hint on how I can manage that?

Regards
Joerg

PS: I hope my intention is clear… :slight_smile:

The context menu via right mouse click provides the solution.
