Operators¶

Name	Description
`$geoWithin`	Selects geometries within a bounding GeoJSON geometry. The 2dsphere and 2d indexes support `$geoWithin`.
`$geoIntersects`	Selects geometries that intersect with a GeoJSON geometry. The 2dsphere index supports `$geoIntersects`.
`$near`	Returns geospatial objects in proximity to a point. Requires a geospatial index. The 2dsphere and 2d indexes support `$near`.
`$nearSphere`	Returns geospatial objects in proximity to a point on a sphere. Requires a geospatial index. The 2dsphere and 2d indexes support `$nearSphere`.

Name	Description
`$geometry`	Specifies a geometry in GeoJSON format to geospatial query operators.
`$minDistance`	Specifies a minimum distance to limit the results of `$near` and `$nearSphere` queries. For use with `2dsphere` index only.
`$maxDistance`	Specifies a maximum distance to limit the results of `$near` and `$nearSphere` queries. The 2dsphere and 2d indexes support `$centerSphere`.
`$center`	Specifies a circle using legacy coordinate pairs to `$geoWithin` queries when using planar geometry. The 2d index supports `$center`.
`$centerSphere`	Specifies a circle using either legacy coordinate pairs or GeoJSON format for `$geoWithin` queries when using spherical geometry. The 2dsphere and 2d indexes support `$centerSphere`.
`$box`	Specifies a rectangular box using legacy coordinate pairs for `$geoWithin` queries. The 2d index supports `$box`.
`$polygon`	Specifies a polygon to using legacy coordinate pairs for `$geoWithin` queries. The 2d index supports `$center`.
`$uniqueDocs`	Deprecated. Modifies a `$geoWithin` and `$near` queries to ensure that even if a document matches the query multiple times, the query returns the document once.
