• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y lang van hoi. hieu va cam duc va ((trinh hoa) OR (minh hoa)) ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y lang van hoi. hieu va cam duc va ((trinh hoa) or (minh hoa)) ((cua viet) OR (ca viet))".
