• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((danh xay) OR (anh xay)) hoi. hieu danh nhan luc van hanh va ((cua tre) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((danh xay) OR (anh xay)) hoi. hieu danh nhan luc van hanh va ((cua tre) or (su triet))".
