Search by uploaded image is one of unique features for gazopa. From search engine provider’s point of view, whether or not to accept uploaded image as a search key is a big issue. If I use a metaphor of baseball to describe these differences, to accept uploaded image is that a batter does not know what kind of ball the pitcher throw, a ball of baseball or a ball of football or a ball of valley ball etc. The batter needs to hit a ball even though a ball is not for baseball. On the contrary, using an indexed image with metadata as a search key rather than using uploaded image is that a batter understands a sign of catcher to pitcher and hits a ball. I think you understand how difficult it is to process uploaded image as a search key from this metaphor.
