The geo_shape data type facilitates the indexing of and searching with arbitrary geoshapes such as rectangles, lines and polygons. If the data being indexed contains shapes other than just points, it is necessary to use this mapping. If the data contains only points, it can be indexed as either geo_point or geo_shape. porche bois porche boxter near me
