Nhat Nguyen created LUCENE-10106:
------------------------------------

             Summary: Sort optimization mistakenly skips the first documentshttps://github.com/elastic/elasticsearch/pull/73324
                 Key: LUCENE-10106
                 URL: https://issues.apache.org/jira/browse/LUCENE-10106
             Project: Lucene - Core
          Issue Type: Bug
          Components: core/search
    Affects Versions: 8.9, main (9.0)
            Reporter: Nhat Nguyen
            Assignee: Nhat Nguyen


[~romseygeek] and I looked into a test [failure|https://github.com/elastic/elasticsearch/pull/73324] that occurs in Elasticsearch with Lucene 9. The first documents of subsequent segments are mistakenly skipped when sort optimization is enabled. We should initialize `maxDocVisited` in NumericComparator to -1 instead of 0.
