• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (ho chieu)) sach - hanh mang cua thong ((cong tap) OR (cong tac)) quan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (ho chieu)) sach - hanh mang cua thong ((cong tap) OR (cong tac)) quan cap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (ho chieu)) sach - hanh mang cua thong ((cong tap) OR (cong tac)) quan cap*.
