This doesn't really seem like a very compelling use case. Surely more 
modern search technologies would be a significantly more effective way of 
addressing the same problem at the user level, but with a significantly 
better user experience? Can you walk me through what a typical user might 
search for in a way that metadata with a scheme would affect the result? 
I'm having trouble figuring out what a suitable "non-preferred term" might 
be. For example, I did a search on direct.gov.uk for "how do i report 
foreign income for tax purposes", which gave me the same top result as 
Google did for that same search (with a site restrict), and did not appear 
to be in any way affected by metadata terms that used schemes.
