      Using the geoNear command returns a structure that contains stats such as number of documents scanned, average distance and maximum distance. When using the distanceMultiplier parameter (to get values in meters, rather than degrees), the average distance is properly scaled using the distance multiplier, but the maximum distance is not scaled.
