public class Geo3DDocValuesField extends Field
An per-document 3D location field.

Sorting by distance is efficient. Multiple values for the same field in one document is allowed.

This field defines static factory methods for common operations:

  • TBD

If you also need query operations, you should add a separate Geo3DPoint instance.

WARNING: Values are indexed with some loss of precision from the original double values (4.190951585769653E-8 for the latitude component and 8.381903171539307E-8 for longitude).

      public static final FieldType TYPE
      Type for a Geo3DDocValuesField

      Each value stores a 64-bit long where the three values (x, y, and z) are given 21 bits each. Each 21-bit value represents the maximum extent in that dimension for the defined planet model.

    • newDistanceSort

      public static SortField newDistanceSort(String field, double latitude, double longitude, double maxRadiusMeters, PlanetModel planetModel)
      Creates a SortField for sorting by distance within a circle.

      This sort orders documents by ascending distance from the location. The value returned in FieldDoc for the hits contains a Double instance with the distance in meters.

      If a document is missing the field, then by default it is treated as having Double.POSITIVE_INFINITY distance (missing values sort last).

      If a document contains multiple values for the field, the closest distance from the circle center is used.

      Parameters:
      field - field name. must not be null.
      latitude - latitude at the center: must be within standard +/-90 coordinate bounds.
      longitude - longitude at the center: must be within standard +/-180 coordinate bounds.
      maxRadiusMeters - is the maximum radius in meters.
      Returns:
      SortField ordering documents by distance
      Throws:
      IllegalArgumentException - if field is null or circle has invalid coordinates.

    • newPathSort

      public static SortField newPathSort(String field, double[] pathLatitudes, double[] pathLongitudes, double pathWidthMeters, PlanetModel planetModel)
      Creates a SortField for sorting by distance along a path.

      This sort orders documents by ascending distance along the described path. The value returned in FieldDoc for the hits contains a Double instance with the distance in meters.

      If a document is missing the field, then by default it is treated as having Double.POSITIVE_INFINITY distance (missing values sort last).

      If a document contains multiple values for the field, the closest distance along the path is used.

      Parameters:
      field - field name. must not be null.
      pathLatitudes - latitude values for points of the path: must be within standard +/-90 coordinate bounds.
      pathLongitudes - longitude values for points of the path: must be within standard +/-180 coordinate bounds.
      pathWidthMeters - width of the path in meters.
      Returns:
      SortField ordering documents by distance
      Throws:
      IllegalArgumentException - if field is null or path has invalid coordinates.

    • newOutsideDistanceSort

      public static SortField newOutsideDistanceSort(String field, double latitude, double longitude, double maxRadiusMeters, PlanetModel planetModel)
      Creates a SortField for sorting by outside distance from a circle.

      This sort orders documents by ascending outside distance from the circle. Points within the circle have distance 0.0. The value returned in FieldDoc for the hits contains a Double instance with the distance in meters.

      If a document is missing the field, then by default it is treated as having Double.POSITIVE_INFINITY distance (missing values sort last).

      If a document contains multiple values for the field, the closest distance to the circle is used.

      Parameters:
      field - field name. must not be null.
      latitude - latitude at the center: must be within standard +/-90 coordinate bounds.
      longitude - longitude at the center: must be within standard +/-180 coordinate bounds.
      maxRadiusMeters - is the maximum radius in meters.
      Returns:
      SortField ordering documents by distance
      Throws:
      IllegalArgumentException - if field is null or location has invalid coordinates.

    • newOutsideBoxSort

      public static SortField newOutsideBoxSort(String field, double minLatitude, double maxLatitude, double minLongitude, double maxLongitude, PlanetModel planetModel)
      Creates a SortField for sorting by outside distance from a box.

      This sort orders documents by ascending outside distance from the box. Points within the box have distance 0.0. The value returned in FieldDoc for the hits contains a Double instance with the distance in meters.

      If a document is missing the field, then by default it is treated as having Double.POSITIVE_INFINITY distance (missing values sort last).

      If a document contains multiple values for the field, the closest distance to the box is used.

      Parameters:

    • newOutsideLargePolygonSort

      public static SortField newOutsideLargePolygonSort(String field, PlanetModel planetModel, Polygon... polygons)
      Creates a SortField for sorting by outside distance from a large polygon. This differs from the related newOutsideLargePolygonSort in that it does little or no legality checking and is optimized for very large numbers of polygon edges.

      This sort orders documents by ascending outside distance from the polygon. Points within the polygon have distance 0.0. The value returned in FieldDoc for the hits contains a Double instance with the distance in meters.

      If a document is missing the field, then by default it is treated as having Double.POSITIVE_INFINITY distance (missing values sort last).

      If a document contains multiple values for the field, the closest distance to the polygon is used.

      Parameters:
      field - field name. must not be null.
      polygons - is the list of polygons to use to construct the query; must be at least one.
      Returns:
      SortField ordering documents by distance
      Throws:
      IllegalArgumentException - if field is null or polygon has invalid coordinates.

      Creates a SortField for sorting by outside distance from a path.

      This sort orders documents by ascending outside distance from the described path. Points within the path are given the distance of 0.0. The value returned in FieldDoc for the hits contains a Double instance with the distance in meters.

      If a document is missing the field, then by default it is treated as having Double.POSITIVE_INFINITY distance (missing values sort last).

      If a document contains multiple values for the field, the closest distance from the path is used.

      Parameters:
      field - field name. must not be null.
      pathLatitudes - latitude values for points of the path: must be within standard +/-90 coordinate bounds.
      pathLongitudes - longitude values for points of the path: must be within standard +/-180 coordinate bounds.
      pathWidthMeters - width of the path in meters.
      Returns:
      SortField ordering documents by distance
      Throws:
