• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky lang van hoa. hieu qua coc luc va hanh vi ((cau treo) OR (cau triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ky lang van hoa. hieu qua coc luc va hanh vi ((cau treo) OR (cau triet))*".
