Custom Score-Similarity

Hi, 
I need some insight into the how the document matching actually happens 
and how score is generated.
The basic need driving this desire is to search on multiple fields using 
boolean queries, and computing similarity score, for each field for each 
hit document so as to device a method to smartly select a document from a 
hitlist.
The similarity between fields may want to leverage idf's(Lucene 
statistics). :(

Your Help in sharing online resources or even better your inputs will be 
of great help.

Thanks 
Darshan.

Thanks Ian, I found it a couple of hours back.  Now Trying to figure out 
the code flow. Debugging has never been this insightful :)

http://lucene.apache.org/java/3_4_0/scoring.html would be a good place to 
start.
