> 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.
