Hi,

Below is the code which worked for me.
  
public class ContactSearch {

    public static List<Contact> searchForContacts(String lastName,String postalCode){
        return [select LastName,MailingPostalCode from Contact
                where LastName = :lastName and MailingPostalCode = :postalCode order by LastName,MailingPostalCode desc];
    }
}

Please mark it as solved if my reply was helpful. It will make it available for other as the proper solution.
                                             
Best Regards
Sandhya
