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