Since there have been a few discussions recently of overriding various aspects of Lucene's ranking formula, I got to wondering how difficult it might be to implement something more different from the base tf/idf ranking system that Lucene has built in.
How difficult would it be to implement something like Cover Density ranking for Lucene? Has anyone tried it? Cover density is described at http://citeseer.ist.psu.edu/558750.html , and is supposed to be particularly good for short queries of the type that you get in many web applications.
