• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh chinh tu nhung cong san ((((than cau) OR (thanh chau))) OR (khoan cam))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - hanh chinh tu nhung cong san ((((than cau) or (thanh chau))) or (khoan cam))*.
