Hi, I did not check it in code, but based on earlier comments on ML, it seems that in place updates are not as it sounds - it will rewrite doc values for the segment that is updated. If you really want to avoid index changes, you can maybe use external field: https://lucene.apache.org/solr/guide/6_6/working-with-external-files-and-processes.html <https://lucene.apache.org/solr/guide/6_6/working-with-external-files-and-processes.html> and function queries when evaluating.
