[jira] [Commented] (SOLR-5170) Spatial multi-value distance sort
via DocValues
[ https://issues.apache.org/jira/browse/SOLR-5170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14509521#comment-14509521 ]
Jeff Wartes commented on SOLR-5170:
-----------------------------------
I got tired of maintaining a custom solr build process for the sole purpose of this patch at my work, especially given the deployment changes in Solr 5.0.
Since this patch really just adds new classes, I pulled those files out into a freestanding repository that builds a jar, copied the necessary infrastructure to allow the tests to run, and posted that here:
https://github.com/randomstatistic/SOLR-5170
This repo contains the necessary API changes to the patch to support Solr 5.0. I have not bothered to update the patch in Jira here with those changes, and going forward, I'll probably continue to only push changes to that repo unless someone asks otherwise.

> 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.
