Subject [jira] Commented: (LUCENE-1483) Change IndexSearcher multisegment searches to search each individual segment using a single HitCollector

Mark Miller commented on LUCENE-1483:
-------------------------------------

Here is what that example policy has to be essentially. We just have to create a good way
to do the right conversion I guess. I'll work on whatever you don't put up when you share
your latest optimizations.


{code}
    case SortField.STRING_ORD:
      return new ComparatorPolicy(){
        private FieldComparator comparator = new FieldComparator.StringOrdComparator(numHits,
field);
        private boolean first = true;
        private boolean second = true;
        public FieldComparator nextComparator(FieldComparator oldComparator,
            IndexReader reader, int numHits, int numSlotsFull)
            throws IOException {
          if(first) {
            first = false;
            return comparator;
          } else if(second){
            StringOrdValOnDemComparator comp = new FieldComparator.StringOrdValOnDemComparator(numHits,
field);
            comp.values = ((FieldComparator.StringOrdComparator)comparator).values;
            comp.ords = ((FieldComparator.StringOrdComparator)comparator).ords;
            comp.currentReaderIndex = 1;
            comparator = comp;
            second = false;
            return comp;
          }
          return comparator;
        }};
{code}
