Hi, Sorting does not work on indexed fields anymore (since Lucene 5), unless you use UninvertingReader. Point values don't work with that because they cannot be uninverted.
For sorting it's the same rule for all field types: enable DocValues! You just have to add another field instance with same name using doc values (some numeric type). Uwe Am 26.
