Description

Specifies the minimum and maximum distances from the center point where the documents can be located.

Use this function to specify a distance range where the documents can be located. For more information, refer to MongoDB documentation.

Notes

  • If one from the input parameters (AMin or AMax) is not in use, set that parameter to -1.
  • Specify the distance in meters for GeoJSON data and in radians for legacy coordinate pairs. Specify all distances in the same units as those of the processed documents’ coordinate system.
  • To set the center point coordinates, use the Near method.
