• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang cao hoa. hieu ve ((chat xuc) OR (cam xuc)) ((gia thanh) OR (ban hanh)) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang cao hoa. hieu ve ((chat xuc) OR (cam xuc)) ((gia thanh) or (ban hanh)) vai cua tre*".
