i wrote a simple test...it does work
IndexWriterConfig iwc = new IndexWriterConfig(Version.LUCENE_46,
new StandardAnalyzer(Version.LUCENE_CURRENT));
iwc.setOpenMode(IndexWriterConfig.OpenMode.CREATE_OR_APPEND);anden
Directory index = new RAMDirectory();
writer = new IndexWriter(index, iwc);
Document doc = new Document();
doc.add(new TextField("text","erstes Dokument",Store.YES));
doc.add(new NumericDocValuesField("id",1l));
writer.addDocument(doc);
doc = new Document();
doc.add(new TextField("text","zweites Dokument",Store.YES));
doc.add(new NumericDocValuesField("id",2l));
writer.addDocument(doc);
doc = new Document();
doc.add(new TextField("text","drittes Dokument",Store.YES));
doc.add(new NumericDocValuesField("id",3l));
writer.addDocument(doc);
doc = new Document();
doc.add(new TextField("text","viertes Dokument",Store.YES));
doc.add(new NumericDocValuesField("id",4l));
writer.addDocument(doc);
doc = new Document();
doc.add(new TextField("text","fünftes Dokument",Store.YES));
doc.add(new NumericDocValuesField("id",5l));
writer.addDocument(doc);
writer.commit();
reader = DirectoryReader.open(index);
IndexSearcher searcher = new IndexSearcher(reader);
QueryParser parser = new QueryParser(Version.LUCENE_CURRENT,"text",new
StandardAnalyzer(Version.LUCENE_CURRENT));
Query q = parser.parse("Dokument");
TopDocs docs = searcher.search(q,100);
System.out.println("anzahl treffer = 5 ? " + docs.scoreDocs.length);
FieldCacheRangeFilter<Long> ffilter = FieldCacheRangeFilter.newLongRange("id",
1L, 3l, true , true);
FilteredQuery fq3=new FilteredQuery(q,ffilter);
docs = searcher.search(fq3,100);
System.out.println("anzahl treffer = 3 ? " + docs.totalHits);

Betreff: FieldCacheRangeFilter on docvalue field
Hi,
iam using lucene 4.6.0.
can i use a FieldCacheRangeFilter on a docvalue field?
like
FieldCacheRangeFilter<Long> ffilter =
FieldCacheRangeFilter.newLongRange("dv_id", 0L, Long.MAX_VALUE, true , true);
where dv_id is s NumericDocValue
regards
Sascha
