• If you are trying to use Boolean operators, they must be ALL CAPS: theo chua xang - hanh tang cua nhung ((phung thanh) OR (phuong thanh)) ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chua xang - hanh tang cua nhung ((phung thanh) or (phuong thanh)) ((toan cao) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo chua xang - hanh tang cua nhung ((phung thanh) or (phuong thanh)) ((toan cao) OR (toan tap))*.
