CFMongoDB MapReduce Query

[Joel Spriggs]

Does anyone have any solid examples or guidance on how to use the query parameter in the MapReduce function?  I'm not getting a very clear picture on how to change a typical javascript statement that I would use in the query portion of Mongo's map reduce to the CF version for this library.  For example, this as a sample:

{sessionDate: {$gt: ISODate("2013-07-01T00:00:00.000Z"), $lt: ISODate("2013-12-31T23:59:59.000Z")}}

Pardon me if this is posted twice by the way.  I tried to post this earlier, but don't see the message anymore on the group board.

Any help is appreciated, thanks!
