• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (mot chieu)) sach - thanh trung ((cac dang) OR (cac dan)) cong bang hanh luat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (mot chieu)) sach - thanh trung ((cac dang) OR (cac dan)) cong bang hanh luat".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (mot chieu)) sach - thanh trung ((cac dang) OR (cac dan)) cong bang hanh luat*.
