Stefan Pohl updated LUCENE-4100:
--------------------------------
Description:
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.
