Subject Lucene 6: Recommended way to store numeric values, given the need to form term vocabulary?
Date Wed, 01 Mar 2017 15:11:34 GMT
Lucene beginner here, please excuse me if I’m asking anything obvious.

In Lucene 6, LongField and IntField were renamed to LegacyLongField and LegacyIntField, deprecated
with a JavaDoc suggestion to use LongPoint and IntPoint classes instead.

However, it seems impossible to build a term vocabulary (=enumerate all distinct values) of
these XPoint fields.

As a third option, one can add a field of class NumericDocValuesField. I tried hardtop search
through documentation, alas found no way of building term vocabulary either.

Is there a non-deprecated way of indexing a numeric field in Lucene 6, given the requirement
to build a term vocabulary?
