Hi,
I am trying to tweak BM25Similarity for my use case wherein, I want to
avoid the effects of field-length normalization for certain fields
(return a constant value irrespective of how long was the document).
Currently, both computeWeight and computeNorm methods are defined final
in BM25Sim
How about just indexing the field without norms?

You don't need to do any subclassing for this: just pass parameter b=0
to the constructor.

Hi Robert,
passing b = 0 will influence the similarity across all the fields (no?)
. I wanted it to be field specific. I think Uwe's suggestion of not
indexing norms for specific fields should work better.
Thankx again.

You can use PerFieldSimilarityWrapper to have different BM25 settings per
field.
