• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((trieu tinh) OR (chieu sach)) - thanh trung va thong thong minh ((toan cao) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((trieu tinh) or (chieu sach)) - thanh trung va thong thong minh ((toan cao) OR (toan tap))*".
