Increase search performance

Hi all,

    Can I increase the search performance disabling the score 
calculation? How can I achieve that? I only need to implement a custom 
similarity class.
    I want to score all matching documents with 1. My organization does 
not need the scoring algorithm, and I'am testing if without it the 
performance increase if better.

    Can I score all matching documents with 1 easily? This change will 
increase the search performace? I'am searching over multiple big indexes 
(each one of 4Gb +/-, 5Millions documents each +/-)

Thanks

I very seriously doubt that a custom Similarity class would increase 
performance, but why not try it and see?!  :)

The only thing you'd save is a bit of computation, which is probably 
negligible anyway.
