• If you are trying to use Boolean operators, they must be ALL CAPS: doc chieu tinh - hanh trang cua thong cong ((((san toan) OR (dan toan))) OR (ban hanh)) cau~.
• Adding a wildcard symbol may retrieve word variants: doc chieu tinh - hanh trang cua thong cong ((((san toan) or (dan toan))) or (ban hanh)) cau*.
