• If you are trying to use Boolean operators, they must be ALL CAPS: doc dien anh - hanh trung cua cong trong lanh ((((tuan cao) OR (toan cao))) OR (quang cao))~.
• Adding a wildcard symbol may retrieve word variants: doc dien anh - hanh trung cua cong trong lanh ((((tuan cao) or (toan cao))) or (quang cao))*.
