About the normalization, the norm factors are computed during the indexation step and store in the index. If you keep using the same index (I mean an index created using the default Similarity), you still have the old norm factors computed with the 'norm' method of the default Similarity.
So, don't forget to re-index after changing the Similarity.
I hope this helps.

I am working on assignment about passage retrieval. I need to change the current scoring scheme (tf.idf.norm.etc..) especially removing normalization part. I tried to extends Similarity, but it always came out with normalization. Do I have to change the code of Scorer class for every query ? Or is there more elegant way ?
