Class LatLonShapePolygonQuery

java.lang.Object

org.apache.lucene.search.Query

org.apache.lucene.document.ShapeQuery

org.apache.lucene.document.LatLonShapePolygonQuery

final class LatLonShapePolygonQuery
extends ShapeQuery

Finds all previously indexed geo shapes that intersect the specified arbitrary.

Note:

• Dateline crossing is not yet supported. Polygons should be cut at the dateline and provided as a multipolygon query

The field must be indexed using LatLonShape.createIndexableFields(java.lang.String, org.apache.lucene.geo.Polygon) added per document.
