To answer your question, in short I don't know. That is why I posted the GSoC project.

How scoring filters can extend the ScoringFilter extension point [1], etc. Other examples of how this works can be seen in the tld plugin, and of course the other scoring plugins available in trunk and 2.x branches. We currently have some wiki pages dedicated to learning how to write plugins for Nutch [2]. This is as good a starting point as any to get your familiar with the plugin extension point mechanism. > I'm currently following the Nutch 1.x wiki for Becoming a developer. > Excellent.
