-----------------------------------
Summary: add newDistanceSort to sandbox LatLonPoint
Key: LUCENE-7099
URL: https://issues.apache.org/jira/browse/LUCENE-7099
Project: Lucene - Core
Issue Type: Bug
Reporter: Robert Muir
This field does not support sorting by distance, which is a very common use
case.
We can add {{LatLonPoint.newDistanceSort(field, latitude, longitude)}} which
returns a suitable SortField. There are a lot of optimizations esp when e.g.
the priority queue gets full to avoid tons of haversin() computations.
Also, we can make use of the SortedNumeric data to switch
newDistanceQuery/newPolygonQuery to the two-phase iterator api, so they aren't
doing haversin() calls on bkd leaf nodes. It should look a lot like LUCENE-7019
