Answer 1

To simulate joins you have to output a doc with an _id in it, the value of the _id needs to point to an actual _id of a document. Then you can make use of include_docs=true to pull in the related documents. Example with many-to-many here: http://danielwertheim.se/couchdb-many-to-many-relations/

If this is not applicable, you can make a two step manual join by first returning custom keys. Then make a second query against the all documents view, with multiple keys specified.
