What is the test for obtaining a warrant for search warrant for a home search?

"The Fourth Amendment requires that a warrant particularly describe both the place to be searched and the person or things to be seized. The description must be specific enough to enable the person conducting the search reasonably to identify the things authorized to be seized." United States v. Spilotro, 800 F.2d 959, 963 (9th Cir.1986). One factor to consider in determining whether a warrant sufficiently defines the objects to be seized is "whether the government was able to describe the items more particularly in light of the information available to it at the time the warrant was issued."
