Exactly. However, one event when Xyz's first came out it was ruled so that you COULD search.

As for Castor and Veiler, one event ruled that it would negate Castor, but after the event, they changed the ruling so that it wouldn't stop the second summon from happening.

Hopefully that tells you that Konami sometimes doesn't know the rules of their own game.
