Hi,
nutch uses lucene.
So you will find that interesting:
http://lucene.apache.org/java/docs/api/org/apache/lucene/search/ 
Similarity.html
Beside that nutch uses a kind of opic:
http://lucene.apache.org/nutch/nutch-nightly/docs/api/org/apache/ 
nutch/scoring/opic/OPICScoringFilter.html

Also have a look here:
http://svn.apache.org/viewvc/lucene/nutch/trunk/src/java/org/apache/ 
nutch/indexer/Indexer.java?view=markup
search for:
// run scoring filters

Hope this answers your question.

Stefan
