• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu tinh - ((thanh trung) OR (thanh tung)) ((cua thuong) OR (cua truong)) cong san toan tap~.
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - ((thanh trung) or (thanh tung)) ((cua thuong) or (cua truong)) cong san toan tap*.
