Subject Re: How can I get document's top n raw score?
Date Mon, 04 Feb 2008 02:02:43 GMT
I'm not sure I understand what you are asking, but, you can get non- 
normalized scores by using the lower-level non-Hits based search like  
the TopDocs, etc.

However, scores are not really all that comparable across queries.
