• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu tinh - ((hanh trang) OR (canh tranh)) cua hang cong van ((thanh cau) OR (nhanh cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu tinh - ((hanh trang) or (canh tranh)) cua hang cong van ((thanh cau) OR (nhanh cau))".
