"Resolution" is a somewhat vague term here, it usually refers to pixels or 
points per length unit (the infamous "ppi" )

At least in Digikam 7.6.0, both the width and height criteria accept a *range* 
of values. That's easy enough to use as a ">": range between 13000 and 
6'000'000'000... 
"<" is even easier: between 0 and 12999.

OK, this doesn't work for aspect ratio... 

Then again, given what you want to do, a height below 4000 and a width above 
10000 should give you a good starting point. Perhaps add "landscape" for the 
orientation.

And did you check the available exif info? E.g. lens type might have a 
difference between normal and panoramic mode.
