Well, that's not what I meant. What I want is a query parameter to get only the
specified document’s fields on a simple GET /{db}/{docid}. CouchDB should parse
the JSON and returns only the required fields, because in a real scenario there
are times you don’t need the entire document, but just some fields. Lazy
Loading is a well known pattern and it’s really effective.
