Jeff Wartes updated SOLR-5170:
------------------------------
Attachment: SOLR-5170_spatial_multi-value_sort_via_docvalues.patch
Updated to work with Solr 4.9 & LUCENE-5703.
Any chance of realtime-friendly multi-value distance sorting getting into the
mainline anytime soon? I've been building with this patch for getting close to
a year now.

> 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.
