Examples of org.apache.lucene.document.BinaryDocValuesField

org.apache.lucene.document.BinaryDocValuesField
Field that stores a per-document {@link 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 {@link 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 {@link StoredField} instance. @see BinaryDocValues
