public class DerefBytesDocValuesField extends Field
Field that stores
a per-document BytesRef
value. The values are
stored indirectly, such that many documents sharing the
same value all point to a single copy of the value, which
is a good fit when the fields share values. If values
are (mostly) unique it's better to use StraightBytesDocValuesField
. Here's an example usage:
document.add(new DerefBytesDocValuesField(name, new BytesRef("hello")));
If you also need to store the value, you should add a
separate StoredField
instance.

public DerefBytesDocValuesField(String name, BytesRef bytes)
This calls
DerefBytesDocValuesField(name, bytes, false
, meaning by default
it allows for values of different lengths. If your values are all
the same length, use that constructor instead.
