See the Similarity (and DefaultSimilarity) class in the Lucene source
code. There are, of course, many other ways to customize similarity:
Function queries, write your own queries, etc.
More details on what you are trying to customize would help answer
your question.

Hi!
How to can I to customize the calculation of the similarity?
I did my own index processor using the classes IndexWriter and
IndexReader,
because the my calculation of the index is very different the Vector
Model.
Then, based on my own index, I need to calculate the similarity
using the
Lucene.
Obs: I'm using the code is in
http://svn.apache.org/repos/asf/lucene/java/trunk/src/java, because
I see
future problems with the version 2.4 on my app to change to new
versions.
Now, thanks!
