What is the test for determining whether a search warrant can be issued in a different state?

We know that the legality of a search does not depend "on the law of the particular State in which the search occurs." California v. Greenwood, 486 U.S. 35, 43, 108 S.Ct. 1625, 1630, 100 L.Ed.2d 30 (1988). It is a question of federal constitutional law, even if the state gives greater protection.

We also know that the legality of an arrest does not depend upon the law of the particular state where the arrest occurs. That, too, is a question of federal constitutional law, even if the state gives greater protection. Barry v. Fowler, 902 F.2d 770, 773 (9th Cir.1990).
