Subject [jira] [Commented] (SOLR-5170) Spatial multi-value distance sort via DocValues
Date Mon, 09 Jan 2017 21:42:58 GMT


David Smiley commented on SOLR-5170:

The fastest is very likely "LatLonDocValuesField", currently hiding out in Lucene sandbox.
 There are some really clever tricks it does.

Interested in adding a Solr adapter for it?

> 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.
