Examples of org.apache.lucene.document.SortedNumericDocValuesField

org.apache.lucene.document.SortedNumericDocValuesField
Field that stores a per-document long values for scoring, sorting or value retrieval. Here's an example usage:
```
 document.add(new SortedNumericDocValuesField(name, 5L)); document.add(new SortedNumericDocValuesField(name, 14L)); 
```
Note that if you want to encode doubles or floats with proper sort order, you will need to encode them with {@link NumericUtils}:
```
 document.add(new SortedNumericDocValuesField(name, NumericUtils.floatToSortableInt(-5.3f))); 
```
If you also need to store the value, you should add a separate {@link StoredField} instance.
