In one project we index an empty file with the same path into a new 
index and merge that with the old one. IIRC the new one is favoured over 
the older one and since it does not contain any words, it is never found.

Hope that helps, I can look up the details if needed. It seems to be 
working for long enough that I have forgotten how we do it ;-)
