    3. Added a new method IndexReader.setNorm(), that permits one to
       alter the boosting of fields after an index is created.
   
  + 4. Distinguish between the final position and length when indexing a
  +    field.  The length is now defined as the total number of tokens,
  +    instead of the final position, as it was previously.  Length is
  +    used for score normalization (Similarity.lengthNorm()) and for
  +    controlling memory usage (IndexWriter.maxFieldLength).  In both of
  +    these cases, the total number of tokens is a better value to use
  +    than the final token position.  Position is used in phrase
  +    searching (see PhraseQuery and Token.setPositionIncrement()).
