• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - hanh tinh cua bang cong san ((((van cau) OR (van dao))) OR (cua cau))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh tinh cua bang cong san ((((van cau) or (van dao))) or (cua cau))*.
