• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) sach - thanh ((cong va) OR (cong tac)) nhung cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) sach - thanh ((cong va) OR (cong tac)) nhung cong dan than cau".
