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