I think you can do this using the linked-documents feature of the indexer. If
your map function emits a value that’s an object containing a “_id” property,
then the view will treat that index entry as though it were generated by the
document with that ID, so if you query with include_docs the contents of the
linked document will be returned.

Sure. In your example, the map function just has to do
emit(doc.fname, null);
emit(doc.lname, null);
So now both the first and last names are in the index, so view queries will
find both first and last names matching your key.
