Errors or other messages returned (if any).
N/A

Interesting... These sort of erroneous results seem to be quite rare, but searching chari-gal inpool:true returns 82 results with almost none of them actually being in a pool. If I had to guess, could it be that the pictures were once in a pool and the site remembers it?

I guessed that they could be in inactive pools, but I couldn't find any of those five images.

I doubt this is the cause, as the inpool metatag work properly fine on inactive pools.
