This PR adds a
points_only
option (defaults tofalse
) to the GeoShapeFieldMapper that exposes the pointsOnly optimization in lucene's RecursivePrefixTreeStrategy. This optimization short-circuits DFS traversal when it is known that the field contains points only. To enforce this option theGeoShapeFieldMapper
has been updated to throw a MapperParsingException for anyShape
that is not of typePoint
when the option is set totrue
. Randomized testing is added and docs are updated. ShapeCollection has also been updated to eventually support MultiPoint. Limitations of S4j are currently the only blocker.closes #12856
