• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (tien anh)) - ((hanh trung) OR (manh trung)) cap dung cong manh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien anh) OR (tien anh)) - ((hanh trung) or (manh trung)) cap dung cong manh toan ban".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien anh) OR (tien anh)) - ((hanh trung) or (manh trung)) cap dung cong manh toan ban*.
