• If you are trying to use Boolean operators, they must be ALL CAPS: su sach _ sang ma hoi. hieu ((ve cam) OR (((ve cham) OR (va cham)))) thuc dan dinh dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach _ sang ma hoi. hieu ((ve cam) or (((ve cham) OR (va cham)))) thuc dan dinh dai cua te*".
