• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((tang ma) OR (trong xa)) hoi. hieu ve cam hoc va ((danh sai) OR (danh bat)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((tang ma) or (trong xa)) hoi. hieu ve cam hoc va ((danh sai) OR (danh bat)) cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((tang ma) or (trong xa)) hoi. hieu ve cam hoc va ((danh sai) OR (danh bat)) cua te*.
