Still very limited and frankly all a bit low level primitives. Unless you are a search expert, you won't be able to do much productive with this stuff. If you are, it might fit a few use cases. But then, why limit yourself to just this stuff?

The point of that of course being that the target audience for this stuff is actually people that for whatever reason are a bit shy using the right tools for the right job here and are probably lacking a lot of expertise. The intersection of people with the expertise that would be happy with this narrow subset of functionality is just not a lot of people.
