Keyword Tag Search Problem

Is there a particular reason you add every folder as a separate collection instead of the parent folder? [/quote]

Yes; I only ever want digiKam to see the finished jpegs; I don’t want to wade through hundreds of RAWs, converted RAWs, PSDs, and various other variants and versions; I just want to see a single example of the image.
If I can see the finished jpeg, then I immediately know exactly where to look for any other versions or formats.

For what it’s worth, I have learned to dislike “stacks” and “version sets” and see them only as a source for confusion.

[quote]If it’s the exact same files, did you already try to copy those and only those to another location and add that as a collection to digikam - to see if the problem occurs as well?

The behavior is so erratic that it is a bit hard to explain.
I first thought that, once a thumbnail refused to display, that it always behaved in that manner; however, last night, I just started at the bottom of the tag tree and worked my up, and I found images affected from all years randomly scattered throughout; and, images that I know for a fact were not displaying properly were displaying fine and others that had not previously been affected were exhibiting the problem. (I didn’t get very far up the tree)
That being said, there is one particular tag group that has certain thumbnails that, once they disappear, they have stayed disappeared; however, in that same group, there are others that disappear for days, only to reappear later.
That is a good experiment you described and I will definitely try it.
I had considered also copying some of them onto one of our other machines and seeing what the other machine’s digiKam did with them.

Thanks for the idea.
