You can override org.apache.lucene.search.Similarity/DefaultSimilarity to tweak quite a lot of stuff.
computeNorm() may be the method you are interested in. Called at indexing time so be sure to use the same implementation at index and query time, using IndexWriterConfig.setSimilarity() and IndexSearcher.setSimilarity(), unless you are clever or like being confused. SweetSpotSimilarity might also be worth a look. -- Ian.
