• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((((lanh tranh) OR (lan tranh))) OR (hoang manh)) cua thong duong van tuan ban~.
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((((lanh tranh) or (lan tranh))) or (hoang manh)) cua thong duong van tuan ban*.
