Downgrade from Japanese free version

The Japanese free version allows you to search by tag, from a list of thousands of tags as well you can filter 18+ images or show only 18+ images, Im not sure why the Canadian version would have such a downgrade? It really disappoints me considering I paid $9 when the free Japanese one gave me all I wanted and I cant get it on this one.
