• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang so hai. hieu va cam xuc ((ban danh) OR (ban hanh)) ((di cau) OR (diem cau)) tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang so hai. hieu va cam xuc ((ban danh) or (ban hanh)) ((di cau) OR (diem cau)) tren*".
