    Details

    • Release Notes Summary:
      Elastic mapping has been updated to avoid indexing error because of a deprecated word delimiter.
    • Upgrade notes:
      Hide

      If you encounter indexing errors because of "negative startOffset", your mapping needs to be updated.
      If you have overridden the Elastic mapping then follow the recommended changes in the ticket.
      Then you need to reindex the repository, visit https://doc.nuxeo.com/nxdoc/elasticsearch-setup/#rebuilding-the-repository-index for more information.

      Description

      The word_delimiter filter can produce indexing errors like:

      startOffset must be non-negative, and endOffset must be >= startOffset, and offsets must not go backwards
      

      Since Lucene 7.x the IndexWriter more aggressive about rejecting backwards offsets: https://issues.apache.org/jira/browse/LUCENE-7626.

      To fix this, you should be able to replace word_delimiter with word_delimiter_graph, which has offset correction logic.
