Uwe Schindler commented on LUCENE-6450:
---------------------------------------
bq. It's impressive how fast this is, without using any NumericField
prefix terms. I think we can explore that later and we should commit
this approach now ..
We should first compare how this behaves on *large* bboxes, so a random test /
perf test spanning large parts of world and large indexes with maaaaaaany
points would be good (whole atlantic, whole africa,...). It is also mentioned
that it does not allow to cross date line, which is easy to do by splitting
into 2 queries, one left of date line, one right. I can help with that. Then we
should also test perf with queries spanning whole pacific :-)

> 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.
