> 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|].
 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.
