$near

$near

The $near operator takes an argument, coordinates for a point in the form of [x, y], and returns a list of objects sorted by distance from nearest to farthest with respect to those coordinates. See the following example:

db.collection.find( { location: { $near: [100,100] } } );

This query will return 100 ordered records with a location field in collection. Specify a different limit using the cursor.limit(), or another geolocation operator, or a non-geospatial operator to limit the results of the query.

Note

Specifying a batch size (i.e. batchSize()) in conjunction with queries that use the $near is not defined. See SERVER-5236 for more information.

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.
