Hi I have tried to upgrade lucene from 4.x to 5.0 recently.I found out from documentation that FieldCache is removed from lucene 5, and I should use DocValues fields for sorting. I upgraded my sources, and everything works fine except spatial sorting by distance. When I looked into PointVectorStrategy I saw that createIndexableFields() creates DoubleFields, but class that used during sorting (DistanceValueSource) works with NumericDocValues. At runtime I got the exception, and advice to use UninveringReader.
I'm a little confused with that. So, in my opinion, there is spatial sorting, which is broken by default. Am I right or missing something? Option to use UninveringReader doesnt works for me because according to https://issues.apache.org/jira/browse/LUCENE-6370 there is no easy way to use UninveringReader with NRT index, which I use.
