Jeff Wartes commented on SOLR-5170:
-----------------------------------
Well, yes, I'm interested. I've got enough other work projects going at the
moment I'm not sure if I'll be able to dedicate much time in the next month or
two, but I wouldn't mind trying to chip at it.
I don't want to pollute this issue, so if you have a few minutes, and could
drop me an email with any pointers about the code areas involved, or references
to any prior art you're aware of, I expect that'd accelerate things a lot.
Thanks.

> Project: Solr
> Issue Type: New Feature

> 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.
