The current definitions of, and distinctions between, nscanned and nscannedobjects are unclear:
http://www.mongodb.org/display/DOCS/Explain#Explain-nscannedObjects
Can we get either better definitions, with examples, or perhaps more fields in the explain() output that can more clearly distinguish between the scanning of index keys, that of individual documents, etc.?
