• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - thanh trung cua cong ((dong dan) OR (duong dan)) toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - thanh trung cua cong ((dong dan) or (duong dan)) toan tap".
