cho chieu » ho chieu, theo chieu, chon chien
tang luan » dung luan
anh tang » anh bang, anh dang, anh nang

• If you are trying to use Boolean operators, they must be ALL CAPS: cho chieu sach - anh tang luan ((thong cong) OR (trong cong)) tan than cap~.
• Adding a wildcard symbol may retrieve word variants: cho chieu sach - anh tang luan ((thong cong) or (trong cong)) tan than cap*.
