• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien tinh) OR (khien tinh)) - ((thanh trung) OR (hanh trinh)) cua hang cong vang toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien tinh) OR (khien tinh)) - ((thanh trung) or (hanh trinh)) cua hang cong vang toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien tinh) OR (khien tinh)) - ((thanh trung) or (hanh trinh)) cua hang cong vang toan ban*.
