Subject [jira] [Commented] (SOLR-5170) Spatial multi-value distance sort via DocValues
Date Tue, 10 Jan 2017 20:20:58 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15816053#comment-15816053

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.

> 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.
