    public BytesRef next() throws IOException
    Description copied from interface: `BytesRefIterator`
    Increments the iteration to the next `BytesRef` in the iterator. Returns the resulting `BytesRef` or `null` if the end of the iterator is reached. The returned BytesRef may be re-used across calls to next. After this method returns null, do not call it again: the results are undefined.
    Specified by:
      `next` in interface `BytesRefIterator`
    Overrides:
      `next` in class `FilterLeafReader.FilterTermsEnum`
    Returns:
      the next `BytesRef` in the iterator or `null` if the end of the iterator is reached.
    Throws:
      `IOException` - If there is a low-level I/O error.
