• If you are trying to use Boolean operators, they must be ALL CAPS: ho trieu tinh - hanh tong quan nhung ((cong tan) OR (cong san)) ((toan cao) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - hanh tong quan nhung ((cong tan) OR (cong san)) ((toan cao) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - hanh tong quan nhung ((cong tan) OR (cong san)) ((toan cao) or (van ban))*.
