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