Field that stores a per-document BytesRef value.

The values are stored directly with no sharing, which is a good fit when the fields don't share (many) values, such as a title field. If values may be shared and sorted it's better to use SortedDocValuesField. Here's an example usage:

  document.add(new BinaryDocValuesField(name, new BytesRef("hello")));

If you also need to store the value, you should add a separate StoredField instance.
