For example, suppose I want to find images of cats,
that are licensed
under CC-BY (but not CC-BY-SA or CC-0, etc). How should I go about this?
Usually I use categories. When I search a specific copyright status it's
usually PD (when I don't have space for attribution):

External search engines are useless for tiny distinctions like these,
for instance Google only tracks NC/ND clauses.
