• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky ((dang xa) OR (van xay)) hoi. hieu van hau cuu ban hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky ((dang xa) or (van xay)) hoi. hieu van hau cuu ban hanh vai cua tre*".
