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