org.apache.lucene.search.function.CustomScoreProvider
An instance of this subclass should be returned by {@link CustomScoreQuery#getCustomScoreProvider}, if you want to modify the custom score calculation of a {@link CustomScoreQuery}.
Since Lucene 2.9, queries operate on each segment of an Index separately, so overriding the similar (now deprecated) methods in {@link CustomScoreQuery}is no longer suitable, as the supplied doc ID is per-segment and without knowledge of the IndexReader you cannot access the document or {@link FieldCache}. @lucene.experimental @since 2.9.2


    CustomScoreQuery customScore = new CustomScoreQuery(dq.getQuery(tq),fsQuery){


      @Override
      protected CustomScoreProvider getCustomScoreProvider(IndexReader reader) {
        return new CustomScoreProvider(reader) {
          @Override // TODO: broken, as reader is not used!
          public float customScore(int doc, float subQueryScore, float valSrcScore){
            System.out.println(doc);
            if (dq.distanceFilter.getDistance(doc) == null)
              return 0;
