• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach duy sang tao hoi. hieu su cham soc ((ban hanh) OR (va danh)) ((lai cua) OR (hai cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach duy sang tao hoi. hieu su cham soc ((ban hanh) or (va danh)) ((lai cua) OR (hai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: tu sach duy sang tao hoi. hieu su cham soc ((ban hanh) or (va danh)) ((lai cua) OR (hai cua)) te*.
