             Summary: advanceExact does not work on sorted numeric dvs with Lucene54DocValuesProducer

                 Key: LUCENE-8117
                 URL: https://issues.apache.org/jira/browse/LUCENE-8117
             Project: Lucene - Core
          Issue Type: Bug
    Affects Versions: 7.2
            Reporter: Jim Ferenczi


DocValues are iterators now so old doc values (produced with Lucene54DocValues) also implements
advance and advanceExact. Though sorted numerics produced by Lucene54DocValues are not working
as expected when advanceExact is used. 
In such case, the docValueCount is as expected but the values returned by the iterator for
the document are invalid. This is due to a bug in the implementation of advanceExact in the
producer that does not set the offset of the current doc when the function is used.
