    Description

      This is a follow up to a support thread: http://groups.google.com/group/mongodb-user/browse_thread/thread/7e1f16c81940c24b

      Please allow mapReduce jobs to optionally return full documents instead of placing the result into the value field.

      The _id of the documents would be the reduction key, but the returned value from reduce (or finalize) would be required to be a hash. This makes working with a permanent collection generated by a map/reduce job much nicer.

      I suggest that a new out option be added:

      out:

      {document: 1}
