LUCENE-8117: Fix advanceExact on SortedNumericDocValues produced by
Lucene54DocValues.
> 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
> Fix For: 7.3, 7.2.1
>
> Attachments: LUCENE-8117.patch
>
>
> 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.
