> SOLR-17917 uncovered a test failure when trying to upgrade to Lucene 10.3,
> which [was caused by a change in behavior
> |https://github.com/apache/lucene/issues/15239]in lucene that is the result
> of an optimization in scoring {{TermQuery}} instances.
> The problem manifests in Solr because of how {{DelegatingCollector}}
> (subclasses) can change the {{scoreMode}} in a way which might be
> inconsistent with if/how the delegate Collector may use
> {{Scorable.setMinCompetitive}}.
> While it remains to be seen if the change in behavior in Lucene 10.3 is
> _intentional_ or not, and/or if the docs for the {{ScoreMode}} are
> inaccurate, practically speaking {{DelegatingCollector}} can be updated to
> be explicit about what should happen in these situations.
