Answer 1

In the more recent versions of CouchDB, you can POST to a view with a JSON document called keys, which allows for multi-key lookup. The structure would look something like this:

{"keys": ["first_tag", "second_tag", "third_tag"]}

This could be POSTed to a view that you have that is emitting tags for its respective keys.

This and other querying options are documented here.
