> CompressingStoredFieldsReader.visitDocument (line 597) loops through the
> fields in the input while consulting the StoredFieldVisitor on what to do.
> There is a small optimization that could be done on the last loop iteration.
> If the visitor returns Status.NO then it should be treated as equivalent to
> Status.STOP. As it is now, it will call skipField() which reads needless
> bytes from the DataInput that won't be used.
> With this optimization in place, it is advisable to put the largest text
> field last in sequence -- something the user or search platform (e.g.
> ES/Solr) could do.
