Jeff Wartes commented on SOLR-5170:
-----------------------------------
I've been using this patch with some minor tweaks and solr 4.3.1 in production
for about six months now. Since I was applying it again against 4.6 this
morning, I figured I should attach my tweaks, and mention it passes tests
against 4.6.
This does NOT address the design issues David raises in the initial comment.
The changes vs the initial patchfile allow it to be applied against a greater
range of solr versions, and brings it a little closer to feeling the same as
geofilt's params.

>
> The attached patch implements spatial multi-value distance sorting. In other
> words, a document can have more than one point per field, and using a
> provided function query, it will return the distance to the closest point.
> The data goes into binary DocValues, and as-such it's pretty friendly to
> realtime search requirements, and it only uses 8 bytes per point.
