[jira] [Created] (SOLR-5170) Spatial multi-value distance sort via DocValues

David Smiley created SOLR-5170:
----------------------------------

             Summary: Spatial multi-value distance sort via DocValues
                 Key: SOLR-5170
                 URL: https://issues.apache.org/jira/browse/SOLR-5170
             Project: Solr
          Issue Type: New Feature
          Components: spatial
            Reporter: David Smiley
            Assignee: David Smiley


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.
