> Key: LUCENE-6393
> URL: https://issues.apache.org/jira/browse/LUCENE-6393
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Robert Muir
> Fix For: Trunk, 5.2
>
>
> This hits an assert in SpanScorer because it breaks the javadocs contract of Spans.nextStartPosition():
> * Returns the next start position for the current doc.
> * There is always *at least one start/end position* per doc.
> * After the last start/end position at the current doc this returns NO_MORE_POSITIONS.
