Subject [jira] [Commented] (SOLR-5170) Spatial multi-value distance sort via DocValues
Date Thu, 23 Apr 2015 18:19:40 GMT

    [ 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.
