• If you are trying to use Boolean operators, they must be ALL CAPS: van dung khoa luan ket qua trieu tri dinh ((doanh doanh) OR (doanh hoan)) (thien OR tien).
• The words AND, OR and NOT may confuse the search; try adding quotes: "van dung khoa luan ket qua trieu tri dinh ((doanh doanh) OR (doanh hoan)) (thien or tien)".
