theo chu » theo chieu, cho chu, chao chu
chu sang » chu bang, thu sang, chieu sang

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sang - thanh hang cua dung cong ((manh toan) OR (anh tuan)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo chu sang - thanh hang cua dung cong ((manh toan) or (anh tuan)) cau*.
