BTW, the effort you put into creating a process to totally replace
your index won't be wasted. I pretty much guarantee that you'll have
to re-index everything upon occasion if for no other reason than the
requirements will change. "Oh, you know that field we said never would
be used for phrase searches? We changed our mind"......... "We decided
to support 14 new use cases....." ;)...
