    Modifier and Type | Class and Description
    --- | ---
    `class` | `ByTermUpdateWorkExecutor` This applies the index update operation using the Lucene operation `IndexWriter.updateDocument(org.apache.lucene.index.Term, java.lang.Iterable<? extends org.apache.lucene.index.IndexableField>)`.
    `class` | `UpdateExtWorkExecutor` This applies the index update operation using the Lucene operation `IndexWriter.updateDocument(Term, Iterable)` This is the most efficient way to update the index, but we can apply it only if the Document is uniquely identified by a single term (so no index sharing across entities or Numeric ids).
