• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((lang van) OR (tang van)) hoi. thien van chat duc ban benh vi ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((lang van) OR (tang van)) hoi. thien van chat duc ban benh vi ((cua tre) or (cuu tre))*".
