I'll take a stab at this, but I am not 100% certain. I seem to recall in the implementation (and then in subsequent fixes by Mark) that we ultimately decided, due to the way Unordered is implemented, that it was too difficult to put the payloads in order, so we more or less punted and decided that perhaps it would be fine to deal w/ them in the aggregate anyway. Perhaps this needs to be revisited. -------------------------- Grant Ingersoll http://www.lucidimagination.com/ Search the Lucene ecosystem (Lucene/Solr/Nutch/Mahout/Tika/Droids) using Solr/Lucene: http://www.lucidimagination.com/search --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
