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()).
