dung cong » dung trong
theo chu » cho chu, chao chu, theo yeu
dung cua » dung luan, dung cho

• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo chu)) xang - manh dung cua dung cong san ((than tap) OR (han tap))~.
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo chu)) xang - manh dung cua dung cong san ((than tap) or (han tap))*.
