The person example is indeed better since the same person can belong to 
different subcategories as you note, while the pools at hotel A and B are 
actually distinct objects. I think I will rearrange my tags accordingly.

Regardless of the use case, there really seems to be some undesirable 
behaviour here (aka "bug" :-). I did the following:
*) I added the tag "George" to all photos of my neighbor George.
*) I added the tag "Scream" (the name of a music group) to all photos taken in 
the context of this music group.
*) Since George is a member of Scream, I added "George" as a subcategory of 
"Scream".

Now I would expect the following query results:
1.) query "George" -> all photos of George
2.) query "George&Scream" -> all photos of George taken in the context of 
Scream

The first query works as expected, but the second query gives exactly the same 
results as the first one, which I don't think makes sense. So my questions 
are:
*) Should the two queries above really give the same results?
*) If yes, how can I tag the images and/or rewrite the query to get only those 
photos of George which also include the tag "Scream"?

	Thanks & kind regards,
