• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky tang ma hoi. hieu ((va tham) OR (van chat)) tuc ((va dinh) OR (va tinh)) thai su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky tang ma hoi. hieu ((va tham) or (van chat)) tuc ((va dinh) OR (va tinh)) thai su triet*".
