Robert Muir commented on LUCENE-4100:
-------------------------------------
I spun off a sub-issue (LUCENE-4198) to see how we can first fix this Codec API
so that
you don't need an IndexRewriter and this patch could work "live".
> Maxscore - Efficient Scoring
> ----------------------------

> Key: LUCENE-4100

> At Berlin Buzzwords 2012, I will be presenting 'maxscore', an efficient
> algorithm first published in the IR domain in 1995 by H. Turtle & J. Flood,
> that I find deserves more attention among Lucene users (and developers).
> I implemented a proof of concept and did some performance measurements with
> example queries and lucenebench, the package of Mike McCandless, resulting in
> very significant speedups.
> This ticket is to get started the discussion on including the implementation
> into Lucene's codebase. Because the technique requires awareness about it
> from the Lucene user/developer, it seems best to become a contrib/module
> package so that it consciously can be chosen to be used.
