• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - hanh trang ((cua tuong) OR (cua huong)) tuong tac ((thanh cha) OR (thanh chac))~.
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - hanh trang ((cua tuong) or (cua huong)) tuong tac ((thanh cha) or (thanh chac))*.
