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.
