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, GeoPolygonQuery, and GeoDistanceQuery 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
