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