    Description

      I didn't observe any limitations on the size of a bytes based DocValues field value in the docs. It appears that the limit is 32k, although I didn't get any friendly error telling me that was the limit. 32k is kind of small IMO; I suspect this limit is unintended and as such is a bug. The following test fails:

        public void testBigDocValue() throws IOException {
          Directory dir = newDirectory();
          IndexWriter writer = new IndexWriter(dir, writerConfig(false));
      
          Document doc = new Document();
          BytesRef bytes = new BytesRef((4+4)*4097);//4096 works
          bytes.length = bytes.bytes.length;//byte data doesn't matter
          doc.add(new StraightBytesDocValuesField("dvField", bytes));
          writer.addDocument(doc);
          writer.commit();
          writer.close();
      
          DirectoryReader reader = DirectoryReader.open(dir);
          DocValues docValues = MultiDocValues.getDocValues(reader, "dvField");
          //FAILS IF BYTES IS BIG!
          docValues.getSource().getBytes(0, bytes);
      
          reader.close();
          dir.close();
        }
