Q: Can I filter on Smart Collections
A: No, only Regular Collections can be filtered on.
As explained the filtering itself it based on the technology of Smart Collections. And it is not possible to use Smart Collections within Smart Collections.
Q: Can I filter on stacked photos
A: No, see Known error "No photos found in stacks".
However a good workaround is explained.
Q: Valid character sets
