# Fields that are within a Specified Distance from a Specified Point

## DISTCARTESIAN

The `DISTCARTESIAN` field specifier allows you to find documents that contain fields that define a point (X and Y coordinates) or region that is within a specified distance from a specified point.

You can specify the document position fields either as a pair of fields (corresponding to X and Y coordinate fields), or as a single field (for example a unified `GeospatialType` field).

    FieldText=DISTCARTESIAN{coordX,coordY,dist}:POSITION

The following example matches all documents whose (X,Y) position is within a distance of 5 units of the point (10,11). The position of a document in this example is contained in the `POSITION` field.

    FieldText=DISTCARTESIAN{10,11,5}:POSITION

For more information about using this field specifier, refer to the IDOL Content Component Reference.

## DISTSPHERICAL

The `DISTSPHERICAL` field specifier allows you to find documents that contain location fields that define a point (latitude and longitude) or region that is within a specified distance from a specified point.

You can specify the document location fields either as a pair of fields (corresponding to latitude and longitude fields), or as a single field (for example a unified `GeospatialType` field).

    FieldText=DISTSPHERICAL{lat,long,dist}:LOCATION

The following example matches all documents whose position is within a 20 kilometer radius of San Francisco (37.75N,122.4W). The latitude and longitude position of a document in this example is contained in the fields `LAT` and `LONG`, respectively.

    FieldText=DISTSPHERICAL{37.75,-122.4,20}:LAT:LONG

The following example matches all documents whose position is within a 20 kilometer radius of Cambridge (52.2N,0.1W). The latitude and longitude position of a document in this example is contained in the `LOCATION` field.

    FieldText=DISTSPHERICAL{52.2,0.1,20}:LOCATION
