chieu xanh » chieu sach, chieu sang, chieu tinh
cua thuong » cua truong, cua phuong, ca thuong

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - ((anh sang) OR (anh bang)) cua thuong cong tac quan cao~.
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - ((anh sang) or (anh bang)) cua thuong cong tac quan cao*.
