• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuoc sach)) y nang x hoi. hieu ve bao duc ban thanh vai ((va triet) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (thuoc sach)) y nang x hoi. hieu ve bao duc ban thanh vai ((va triet) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) OR (thuoc sach)) y nang x hoi. hieu ve bao duc ban thanh vai ((va triet) or (cua te))*.
