Subject Re: Subjects DB Matching

Hi Mauro,

I'd go to one of the Lucene mail archives, and search "record  
linkage", there you will find various conversations on the topic [1].   
Also, try googling for that.  In particular, you might look for stuff  
by W. Winkler at the census bureau, amongst others.   There is also  
the Second String package by William Cohen at CMU that may help, but I  
don't know if it scales or how well supported it is.

Also see as a starting  
point.  In short, I think Lucene could facilitate such a system, but  
it probably isn't going to be the main piece.
