• Performing a fuzzy search may retrieve terms with similar spellings: ((ho trieu) OR (mot trieu)) tinh - thanh trung va dung cong dan ((toan cao) or (thuat cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho trieu) OR (mot trieu)) tinh - thanh trung va dung cong dan ((toan cao) OR (thuat cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (mot trieu)) tinh - thanh trung va dung cong dan ((toan cao) or (thuat cao))".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (mot trieu)) tinh - thanh trung va dung cong dan ((toan cao) or (thuat cao))*.
