via DocValues
[ https://issues.apache.org/jira/browse/SOLR-5170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13742654#comment-13742654 ]
Robert Muir commented on SOLR-5170:
-----------------------------------
why use BINARY vs SORTED_SET? that has a much easier fit in solr to boot. its designed for multiple values...

> 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.
