@Override
public void hitExecute(SearchContext context, HitContext hitContext) {
    // it might make sense to cache the TermDocs on a shared fetch context and just skip here)
    // it is going to mean we work on the high level multi reader and not the lower level reader as is
    // the case below...
    long version;
    try {
        BytesRef uid = Uid.createUidAsBytes(hitContext.hit().type(), hitContext.hit().id());
        version = Versions.loadVersion(
