$nearSphere
¶ New in version 1.8.
The
$nearSphere
operator is the spherical equivalent of the$near
operator.$nearSphere
returns all documents near a point, calculating distances using spherical geometry.Changed in version 2.2.3: Before 2.2.3, a geospatial index must exist on a field holding coordinates before using any of the geolocation query operators. After 2.2.3, applications may use geolocation query operators without having a geospatial index; however, geospatial indexes will support much faster geospatial queries than the unindexed equivalents.
Note
A geospatial index must exist on a field and the field must hold coordinates before you can use any of the geolocation query operators.
