org.apache.lucene.facet.associations.MultiAssociationsFacetsAggregator
A {@link FacetsAggregator} which chains multiple aggregators for aggregatingthe association values of categories that belong to the same category list. While nothing prevents you from chaining general purpose aggregators, it is only useful for aggregating association values, as each association type is written in its own list. @lucene.experimental

    aggregators.put(tags, new SumIntAssociationFacetsAggregator());
    aggregators.put(genre, new SumFloatAssociationFacetsAggregator());
    FacetsAccumulator fa = new FacetsAccumulator(fsp, indexReader, taxoReader) {
      @Override
      public FacetsAggregator getAggregator() {
        return new MultiAssociationsFacetsAggregator(aggregators);
      }
    };
    FacetsCollector fc = FacetsCollector.create(fa);
    
    // MatchAllDocsQuery is for "browsing" (counts facets
