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