Class DerefBytesDocValuesField
java.lang.Object
org.apache.lucene.document.Field
org.apache.lucene.document.DerefBytesDocValuesField
- All Implemented Interfaces:
- IndexableField
public class DerefBytesDocValuesField
- extends Field
This class provides a Field
that enables storing
of 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.
