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

            Field sortedDVField = null;
            Field sortedSetDVField = new SortedSetDocValuesField("sortedsetdv", new BytesRef());
            doc.add(idField);
            doc.add(newField(random, "field", "some text contents", storedTextType));
            if (defaultCodecSupportsDocValues()) {
              binaryDVField = new BinaryDocValuesField("binarydv", new BytesRef());
              numericDVField = new NumericDocValuesField("numericdv", 0);
              sortedDVField = new SortedDocValuesField("sorteddv", new BytesRef());
              doc.add(binaryDVField);
              doc.add(numericDVField);
              doc.add(sortedDVField);
