trung thai » trong thai, trang thai, trung tai
thuong ban » thuong han, thuong lan, tuong ban

• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sach) OR (trieu tinh)) - manh ((trung thai) OR (trung hai)) bang thuong ban than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) or (trieu tinh)) - manh ((trung thai) OR (trung hai)) bang thuong ban than cap~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) or (trieu tinh)) - manh ((trung thai) OR (trung hai)) bang thuong ban than cap*.
