Operators运算符

Query Selectors查询选择器

Name名称Description描述
$geoIntersects Selects geometries that intersect with a GeoJSON geometry. 选择与GeoJSON几何图形相交的几何图形。The 2dsphere index supports $geoIntersects.2dsphere索引支持$geoIntersects。
$geoWithin Selects geometries within a bounding GeoJSON geometry. 选择边界GeoJSON几何图形中的几何图形。The 2dsphere and 2d indexes support $geoWithin.2dsphere和2d索引支持$geoWithin。
$near Returns geospatial objects in proximity to a point. 返回点附近的地理空间对象。Requires a geospatial index. 需要地理空间索引。The 2dsphere and 2d indexes support $near.2dsphere和2d索引支持$near。
$nearSphere Returns geospatial objects in proximity to a point on a sphere. 返回球体上某个点附近的地理空间对象。Requires a geospatial index. 需要地理空间索引。The 2dsphere and 2d indexes support $nearSphere.2dsphere和2d索引支持$nearSphere。

Geometry Specifiers几何体说明符

Name名称Description描述
$box Specifies a rectangular box using legacy coordinate pairs for $geoWithin queries. 为$geoWithin查询指定使用传统坐标对的矩形框。The 2d index supports $box.2d索引支持$box。
$center Specifies a circle using legacy coordinate pairs to $geoWithin queries when using planar geometry. 使用平面几何图形时，使用传统坐标对在$geoWithin查询中指定圆。The 2d index supports $center.2d索引支持$center。
$centerSphere Specifies a circle using either legacy coordinate pairs or GeoJSON format for $geoWithin queries when using spherical geometry. 在使用球形几何体时，为$geoWithin查询指定使用传统坐标对或GeoJSON格式的圆。The 2dsphere and 2d indexes support $centerSphere.2dsphere和2d索引支持$centerSphere。
$geometry Specifies a geometry in GeoJSON format to geospatial query operators.为地理空间查询运算符指定GeoJSON格式的几何图形。
$maxDistance Specifies a maximum distance to limit the results of $near and $nearSphere queries. 指定最大距离以限制$near和$nearSphere查询的结果。The 2dsphere and 2d indexes support $maxDistance.2dsphere和2d索引支持$maxDistance。
$minDistance Specifies a minimum distance to limit the results of $near and $nearSphere queries. 指定限制$near和$nearSphere查询结果的最小距离。For use with 2dsphere index only.仅适用于2dsphere索引。
$polygon Specifies a polygon to using legacy coordinate pairs for $geoWithin queries. 指定要在$geoWithin查询中使用传统坐标对的多边形。The 2d index supports $center.2d索引支持$center。
$uniqueDocs Deprecated. 不赞成。Modifies a $geoWithin and $near queries to ensure that even if a document matches the query multiple times, the query returns the document once.修改$geoWithin和$near查询，以确保即使文档多次匹配查询，查询也会返回一次文档。
