Hello,
I am trying to do a faceted search across two parallel indexes with a
ParallelCompositeReader.
My problem is that I only get facet results from the first reader in the
array of composite readers. This problem only occurs after upgrading to
Lucene version 4_7_0+.
If I switch the order of the readers, again the first one in the array
is the only index that gives facet results.
Regards,

CompositeReader primaryReader =
DirectoryReader.open(FSDirectory.open((new
File("index-directory")).toPath()));
CompositeReader suppReader = DirectoryReader.open(FSDirectory.open((new
File("supp-directory")).toPath()));
CompositeReader[] readers = {primaryReader, suppReader};
ParallelCompositeReader pcr = new ParallelCompositeReader(readers);
FacetsCollector fc = new FacetsCollector();
TopDocs td = FacetsCollector.search(searcher, new MatchAllDocsQuery(),
10, fc);
Directory taxoDir = FSDirectory.open((new
File("taxonomy-directory")).toPath());
TaxonomyReader taxoReader = new DirectoryTaxonomyReader(taxoDir);
Facets facets = new FastTaxonomyFacetCounts(taxoReader,
CujoFacetsConfig.getFacetsConfig(), fc);
List<FacetResult> results = facets.getAllDims(10);
