Having a problem with following query:

db.test.count({"location" : {"$within" : {"$center" : [[ -87, 41], 5]}}, "initial_type" : "x"})

I built an index for geospatial and the above call type. Coordinates are reduced for privacy reasons fyi...

The find() returns exceptionally fast...but the count above just hangs. Any quick thoughts? thx
