David Smiley updated SOLR-13467:
--------------------------------
Description:
Here I'm adding a dependency on [Google S2 Geometry|http://s2geometry.io]
(121KB) so that we can use {{prefixTree="s2"}} on a spatial field type that is
using Geo3D. Lucene spatial-extras already has this dependency, albeit it is
optional. I enhanced tests to exercise it.
Additionally, I document here a strictness Geo3D has in which the polygon
points must be provided in a particular order or else the interpretation of the
shape is inverted. This so-called "right hand rule" order is somewhat standard
but some libs (like JTS) don't care.
was:There's a limitation/gotcha on Geo3D in which the polygon points must be
provided in a particular order or else the interpretation of the same is
inverted. In addition, lets add a reference to {{prefixTree="s2"}} and
possibly a test for the same.
Component/s: spatial
Summary: Spatial: Add S2 lib for more efficient Geo3D indexes (was:
Ref guide: spatial: document Geo3D better)
Originally this was just going to be about documenting the point order in the
ref guide but then I added a test, then added S2, then realized -- oh yeah, S2
isn't in Solr, so.... scope creep.
It'd be nice to have S2 be the default when Geo3D is used, but that's best done
in Lucene and thus a separate issue. This would require knowledge of the
Version since it affects the index. Any way I don't have time for that now.
