• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) sach - thanh truong cua trong cong tap ((quan tap) OR (quan tam))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) sach - thanh truong cua trong cong tap ((quan tap) OR (quan tam))*.
