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