There are many similar tags that I believe refer to the same thing. These could included in "paw_print_clothing".
Also I found "pawprint" and "paw_print".

print tags are quite messy.
For pawprints, I think there must be two separate tags, one being paw_markings(i.e. a paw tattoo), and the other paw_print(for clothing prints).
As for the clothing, I don't think it's good to have <x>_print_<piece of clothing> for every possible combination, I would prefeer aliasing any paw_print_<x> to paw_print_clothing, and do the same for other print tags.
Searching for specifics would be done simply with "paw_print_clothing print_panties" for example, while paw_print_panties would be alised to paw_print_clothing.
