      Create a collection from MapReduce query that contains geoJson points in the value.location field. Add a 2dsphere index to that embedded field. Run a $geoWithin query such as:

      "value.avg_location" : {
      "$geoWithin" :

      { "$polygon" : [ [ -122.07496047019957, 37.65882781135178 ], [ -122.07496047019957, 37.663906822384874 ], [ -122.0871913433075, 37.663906822384874 ], [ -122.0871913433075, 37.65882781135178 ], [ -122.07496047019957, 37.65882781135178 ] ] }

      When I run a query on an indexed location field (which contains geoJSON points) I notice that the query is doing a collection scan. Deleting the index and running the query takes about 5 minutes. After adding the index back again, the query still takes about 5 minutes. Here are the steps I've taken to debug:
