Nicholas Knize updated LUCENE-7381:
-----------------------------------
Attachment: LUCENE-7381.patch
Initial patch for adding a new {{RangeField}} to sandbox that indexes ranges up
to 4 dimensions representing:
* 1d : single axis
* 2d : bounding box
* 3d : bounding cube
* 4d : tesseract
A new {{RangeFieldQuery}} class is also added that supports intersects, within,
and contains query.
Multiple range values per document is supported, as well as indexing and
querying open ended ranges using {{Double.NEGATIVE_INFINITY}} and
{{Double.POSITIVE_INFINITY}}.
Random testing (inspired by the rigorous testing in {{BaseGeoPointTestCase}})
is also provided. It currently tests only 2 dimensions so support for random
dimension testing still needs to be added.
Nearly all of the Point based fields end with {{Point}} but I thought
{{RangePoint}} and {{RangePointQuery}} might be a bit too confusing with
{{PointRangeQuery}}. (naming is hard. the field type can always be refactored)

> I've been tinkering with a new Point-based {{RangeField}} for indexing
> numeric ranges that could be useful for a number of applications.
> For example, a single dimension represents a span along a single axis such as
> indexing calendar entries start and end time, 2d range could represent
> bounding boxes for geometric applications (e.g., supporting Point based geo
> shapes), 3d ranges bounding cubes for 3d geometric applications (collision
> detection, 3d geospatial), and 4d ranges for space time applications. I'm
> sure there's applicability for 5d+ ranges but a first incarnation should
> likely limit for performance.
