[jira] [Created] (LUCENE-10126) CompetitiveIterator of NumericComparator can wrongly skip documents

Nhat Nguyen created LUCENE-10126:
------------------------------------

             Summary: CompetitiveIterator of NumericComparator can wrongly skip documents
                 Key: LUCENE-10126
                 URL: https://issues.apache.org/jira/browse/LUCENE-10126
             Project: Lucene - Core
          Issue Type: Bug
          Components: core/search
    Affects Versions: 8.9, 8.10
            Reporter: Nhat Nguyen


The ML team at Elastic reported that a large scroll with an Elasticsearch nightly build that uses Lucene 9.0 snapshot returns fewer documents than expected. I looked into it and found that the competitive iterator can wrongly skip docs with a chunked bulk scorer.
