org.apache.lucene.facet.partitions.PartitionsFacetResultsHandler.mergeResults()
Merge results of several facet partitions. Logic of the merge is undefined and open for interpretations. For example, a merge implementation could keep top K results. Passed {@link IntermediateFacetResult} must be onesthat were created by this handler otherwise a {@link ClassCastException} isthrown. In addition, all passed {@link IntermediateFacetResult} must havethe same {@link FacetRequest} otherwise an {@link IllegalArgumentException}is thrown. @param tmpResults one or more temporary results created by thishandler. @return temporary facet result that represents to union, as specified bythis handler, of the input temporary facet results. @throws IOException on error. @throws ClassCastException if the temporary result passed was not createdby this handler @throws IllegalArgumentException if passed facetResults do nothave the same {@link FacetRequest} @see IntermediateFacetResult#getFacetRequest()
