> We should offer a standard way to force upper-case tokens.  I understand that 
> lowercase is safer for general search quality because some uppercase 
> characters can represent multiple lowercase ones.
> However, having upper-case tokens is often nice for faceting (consider 
> normalizing to standard acronyms)
