How the default ranking works

Hello,
 
   How the hits are ranked in default case. If I have say some query like this:
 
title:"measurement procedure" AND id:ep6289*
 
Say I have some 10 documents matched with that query, how my hits will be displayed. Which record will display first and how it will do the ranking in default case. And also think that I don't have any sort Field.
 
Please give me some resources where I can read all about Indexing, Ranking of Lucene.
 
Thanx,
MTREDDY

You can order it online and have it shipped to you from many online  
bookstores - or buy the PDF directly from Manning online.  Links at

To dig through it yourself, check out IndexSearcher.explain().  To  
dig deeper, look at the javadocs on Similarity.

There is of course a bit on scoring in "Lucene in Action":

You have a copy of this book, right?!  :)
