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