Well, I've kind of come full circle here and I probably oversimplified my
latest example. :-)

Earlier in the thread I have the problem whittled down to getting distinct
values for some redundant data across documents, which involved a simple
reduce function with rereduce, and to do that I need to emit a key that's an
array of multiple document fields. I definitely don't want to return the
entire document in this case since the documents might have reams and reams
of additional data I don't need here since this is ultimately being used to
drive a select box.

Thanks for the input--looks like the follow-up from Zachary covers the
answer--startKey and endKey that are the same should do the trick.

Appreciate everyone's assistance on this--very helpful as I go from "noob"
to "dangerous noob" with CouchDB. :-)
