org.apache.lucene.facet.partitions.IntermediateFacetResult
Intermediate {@link FacetResult} of faceted search.
This is an empty interface on purpose.
It allows {@link FacetResultsHandler} to return intermediate result objects that only it knows how to interpret, and so the handler has maximal freedom in defining what an intermediate result is, depending on its specific logic. @lucene.experimental

          final HashSet<FacetRequest> handledRequests = new HashSet<FacetRequest>();
          for (FacetRequest fr : searchParams.facetRequests) {
            // Handle and merge only facet requests which were not already handled.  
            if (handledRequests.add(fr)) {
              PartitionsFacetResultsHandler frHndlr = createFacetResultsHandler(fr, createOrdinalValueResolver(fr));
              IntermediateFacetResult res4fr = frHndlr.fetchPartitionResult(offset);
              IntermediateFacetResult oldRes = fr2tmpRes.get(fr);
              if (oldRes != null) {
                res4fr = frHndlr.mergeResults(oldRes, res4fr);
