Examples of org.apache.lucene.document.SortedDocValuesField

org.apache.lucene.document.SortedDocValuesField
Field that stores a per-document {@link BytesRef} value, indexed forsorting. Here's an example usage:
```
 document.add(new SortedDocValuesField(name, new BytesRef("hello"))); 
```
If you also need to store the value, you should add a separate {@link StoredField} instance.

    IndexWriterConfig conf = newIndexWriterConfig(TEST_VERSION_CURRENT, new MockAnalyzer(random()));
    RandomIndexWriter writer = new RandomIndexWriter(random(), dir, conf);
    Field idField = new StringField("id", "", Field.Store.NO);
    Field storedBinField = new StoredField("storedBin", new byte[0]);
    Field dvBinField = new BinaryDocValuesField("dvBin", new BytesRef());
    Field dvSortedField = new SortedDocValuesField("dvSorted", new BytesRef());
    Field storedNumericField = new StoredField("storedNum", "");
    Field dvNumericField = new NumericDocValuesField("dvNum", 0);
    
    // index some docs
    int numDocs = atLeast(300);
    for (int i = 0; i < numDocs; i++) {
      idField.setStringValue(Integer.toString(i));
      int length = TestUtil.nextInt(random(), 0, 8);
      byte buffer[] = new byte[length];
      random().nextBytes(buffer);
      storedBinField.setBytesValue(buffer);
      dvBinField.setBytesValue(buffer);
      dvSortedField.setBytesValue(buffer);
      long numericValue = random().nextLong();
      storedNumericField.setStringValue(Long.toString(numericValue));
      dvNumericField.setLongValue(numericValue);
      Document doc = new Document();
      doc.add(idField);
