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