Another way to tackle this could be FunctionQuery. It can create a score

Hi,
Lucene uses a variant version of vector space model for ranking the
documents.
You can look at
1)

the fomula,
2) there is an article some one wrote about the Lucene's Ranking function
vs. standard vsm. However

like the following:

Should this work, or is there some other way to escape double quotes

Hi Dan,
You are describing Simpy :) - http://www.simpy.com/
If you look at Simpy's blog at http://blog.simpy.com/blojsom/blog/ ,
you
will see I started a little series of posts about the analysis of
tagging and bookmarking in Simpy. If I find time, I'll post the next
part of the series tonight.
Thanks Erik, seems Otis keeps a very nice blog about simply
http://blog.simpy.com/blojsom/blog/ that's full of helpful advice on the
topic.
