Yep, you're correct. CopyField is probably your simplest option here as Ahmet suggested. A more complex solution would be your own response writer, but unless and until you index gets cumbersome, I'd avoid that. Plus, storing the copied contents only shouldn't impact search much, since this doesn't add any terms...
