• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ((ky vung) OR (tay vung)) ((ha hoi) OR (hoa hoc)). hieu ve chat luoc van thanh di cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ((ky vung) OR (tay vung)) ((ha hoi) or (hoa hoc)). hieu ve chat luoc van thanh di cuu tre*".
