nutch scoring - documentation

[eyal edri <ey...@gmail.com>]

Hello,

Can anyone direct me to documentation on how the nutch scoring system works?
I want to know how nutch decides who are the -topN xxx pages retrieved when
using the "topN" argument in command line.
I'm not using any indexing/searching (just plain
inject-->crawl-->fetch-->update cycle).

I know nutch-defaults.xml determins the initials scoring for pages, but do
those pages change thier ranking afterwards?

thanks

The scoring is done through the OPIC scoring filter.  You can find it
in the code under src/plugin/scoring-opic.  The comments at the top of
the java file have a url that explains in greater detail the theory
behind the scoring.
