• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) y nang x hoi. hieu va dao duc ban thanh van ((cua triet) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) y nang x hoi. hieu va dao duc ban thanh van ((cua triet) or (cua te))*".
