Bouvier's Law Dictionary, Revised 6th Ed (1856):

SEARCH WARRANT, crim. law, practice. A warrant (q.v.) requiring the officer
to whom it is addressed, to search a house or other place therein specified,
for property therein alleged to have been stolen; and if the same shall be
found upon such search, to bring the goods so found, together with the body
of the person occupying the same, who is named, before the justice or other
officer granting the warrant, or some other justice of the peace, or other
lawfully authorized officer. It should be given under the hand and seal of
the justice, and dated.
     2. The constitution of the United States, amendments, art. 4, declares
that "the right of the people to be secure in their persons, houses, papers
and effects, against unreasonable searches and seizures, shall not be
violated; and no warrants shall issue, but upon probable cause, supported by
oath or affirmation, and particularly describing the place to be searched,
and the person or things to be seized."
     3. Lord Hale, 2 P. C. 149, 150, recommends great caution in granting
such warrants. 1. That they be, not granted without oath made before a
justice of a felony committed, and that the complainant has probable cause
to suspect they are in such a house or place, and his reasons for such
suspicion. 2. That such warrants express that the search shall be made in
day time. 3. That they ought to be directed to a constable or other proper
officer, and not to a private person. 4. A search warrant ought to command
the officer to bring the stolen goods and the person in whose custody they
are, before some justice of the peace. Vide 1 Chit. Cr. Law, 57, 64; 4 Inst.
