• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((dang cau) OR (bang cau)) hoa. hieu ((va cam) OR (va cham)) xuc van hanh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((dang cau) OR (bang cau)) hoa. hieu ((va cam) or (va cham)) xuc van hanh tai cua triet".
