• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu xanh - hanh mang cua nhung cong ((((van toan) OR (van tan))) or (dan than)) ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - hanh mang cua nhung cong ((((van toan) OR (van tan))) OR (dan than)) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh mang cua nhung cong ((((van toan) OR (van tan))) or (dan than)) ban*".
