      Description

      At the moment all spatial capabilities, including basic point based indexing and querying, require the lucene-spatial module. The spatial module, designed to handle all things geo, requires dependency overhead (s4j, jts) to provide spatial rigor for even the most simplistic spatial search use-cases (e.g., lat/lon bounding box, point in poly, distance search). This feature trims the overhead by adding a new GeoPointField type to core along with GeoBoundingBoxQuery and GeoPolygonQuery classes to the .search package. This field is intended as a straightforward lightweight type for the most basic geo point use-cases without the overhead.

      The field uses simple bit twiddling operations (currently morton hashing) to encode lat/lon into a single long term. The queries leverage simple multi-phase filtering that starts by leveraging NumericRangeQuery to reduce candidate terms deferring the more expensive mathematics to the smaller candidate sets.
