• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chinh sach)) - thanh trung cua ((ban huong) OR (ban hang)) dan hang cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chinh sach)) - thanh trung cua ((ban huong) OR (ban hang)) dan hang cau*".
