David Smiley resolved LUCENE-5648.
----------------------------------
Resolution: Fixed
Fix Version/s: 5.0
The "NR" abbreviation is purely used on internal classes and it's referenced a
lot so I don't worry about it's succinct name.
I committed against 5x. LUCENE-5608 (spatial api refactoring) is a dependency
which is still 5x; maybe I should back-port that to 4x now or soon. Or wait a
bit to see if further changes may arrive when I try to facet.

> If you need to index a date/time duration, then the way to do that is to have
> a pair of date fields; one for the start and one for the end -- pretty
> straight-forward. But if you need to index a variable number of durations per
> document, then the options aren't pretty, ranging from denormalization, to
> joins, to using Lucene spatial with 2D as described
> [here|http://wiki.apache.org/solr/SpatialForTimeDurations]. Ideally it would
> be easier to index durations, and work in a more optimal way.
> This issue implements the aforementioned feature using Lucene-spatial with a
> new single-dimensional SpatialPrefixTree implementation. Unlike the other two
> SPT implementations, it's not based on floating point numbers. It will have a
> Date based customization that indexes levels at meaningful quantities like
> seconds, minutes, hours, etc. The point of that alignment is to make it
> faster to query across meaningful ranges (i.e. [2000 TO 2014]) and to enable
> a follow-on issue to facet on the data in a really fast way.
> I'll expect to have a working patch up this week.
