• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty sang ma hoa. hieu ((van cam) OR (van nam)) xuc ((ban danh) OR (ban hanh)) dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty sang ma hoa. hieu ((van cam) or (van nam)) xuc ((ban danh) OR (ban hanh)) dai cua triet".
