Per https://cloud.google.com/appengine/docs/python/ndb/queries#repeated_properties ,
myapp.models.UserPhoto.tags.IN(tags) would be an `OR` query (with its own limits, too), and what you want is instead an `AND` query; I don't think there's a materially faster way to compose the latter wrt what you're doing now. Thus, I would indeed encourage you to explore if the Search API can better match your needs (within its own limits, such as the 10GB index size constraint).
