NumericField traverse order

[Yonghui Zhao]

If we traverse a string field use code below, the value order is string
older.

    Terms terms = reader.terms(“strField");
    if (terms != null) {
      TermsEnum termsEnum = terms.iterator(null);
      BytesRef text;
      while ((text = termsEnum.next()) != null)


How about numeric field.  IntField, LongField, and DoubleField ....

What's the order?   Numeric order?

Thanks
