• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc hien)) sang - ((thanh trung) OR (thanh tung)) cua tong hung manh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc hien)) sang - ((thanh trung) OR (thanh tung)) cua tong hung manh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (hoc hien)) sang - ((thanh trung) OR (thanh tung)) cua tong hung manh toan ban*.
