> 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:
> {code:java}
> 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();
> }
> {code}
