• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh ((((trung tuan) OR (trung tam))) OR (truong cao)) thong huong dan than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh ((((trung tuan) OR (trung tam))) or (truong cao)) thong huong dan than cap".
