(a) Before acting on the application, the issuing official may examine on oath the applicant or any other person who may possess pertinent information, but information other than that contained in the affidavit may not be considered by the issuing official in determining whether probable cause exists for the issuance of the warrant unless the information is either recorded or contemporaneously summarized in the record or on the face of the warrant by the issuing official. The information must be shown by one or both of the following:

(b) If the issuing official finds that the application meets the requirements of this Article and finds there is probable cause to believe that the search will discover items specified in the application which are subject to seizure under G.S. 15A-242, he must issue a search warrant in accordance with the requirements of this Article. The issuing official must retain a copy of the warrant and warrant application and must promptly file them with the clerk. If he does not so find, the official must deny the application.
