If you are handing a user-typed String to (MultiField)QueryParser you  
cannot, be default, prevent any indexed fields from being searched.   
You could, however, create custom QueryParser and  
MultiFieldQueryParser subclasses that could prevent this, I believe,  
by overriding all the various get* methods that return a Query and  
block specific fields as desired.  I'm not quite sure of the details  
and am just mentioning this off the top of my head, so maybe there  
are some issues I haven't considered that make this tougher than just
