When performing a $near or geoNear query on GeoJSON data indexed with a 2dsphere index, the query appears to miss data. This may be an issue with the 2dsphere index, as reindexing changes the number of data elements returned for a geoNear query, but not for a bounding-box $geoWithin query. In this case, all of the data is within the polygon bounded by longitude -90 to -80, and latitude 35 to 45. The only secondary index on the collection is
