Examples of NumericDocValuesField

org.apache.lucene.document.NumericDocValuesField
Field that stores a per-document long value for scoring, sorting or value retrieval. Here's an example usage:
```
 document.add(new NumericDocValuesField(name, 22L)); 
```
If you also need to store the value, you should add a separate {@link StoredField} instance.

    IndexWriter writer = new IndexWriter(dir, conf);
    
    // first segment with NDV
    Document doc = new Document();
    doc.add(new StringField("id", "doc0", Store.NO));
    doc.add(new NumericDocValuesField("ndv", 3));
    writer.addDocument(doc);
    doc = new Document();
    doc.add(new StringField("id", "doc4", Store.NO)); // document without 'ndv' field
    writer.addDocument(doc);
    writer.commit();
