TAG.INTER returns the keys that carry every one of the given tags. If any tag is unused, the result is empty. The order is not defined.

As with TAG.MEMBERS, tags are shared by all logical databases, so a key in any database can appear. In cluster mode, the command answers from the node you send it to.
