• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - hanh dong ((cua trong) OR (cua truong)) ((cong thanh) OR (truong thanh)) san tap~.
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - hanh dong ((cua trong) or (cua truong)) ((cong thanh) or (truong thanh)) san tap*.
