I do not want to interfere, and if I do please let me know.
I am watching this thread, and spotted something in Uwe's answer below 
that also interests me, and I believe is relevant to the matter at hand.

If so, how does Lucene handle the case where a book has several authors, 
each with a name, a weight, etc..
How does one keep them "in sync", so that if I search for books that 
have an author with first name "Robert" and who weighs more than 100 Kg, 
I do not hit the ones that have a combination like this :
author #1 : Einstein, Albert, 101 Kg
author #2 : McNamara, Robert, 075 Kg
