• Performing a fuzzy search may retrieve terms with similar spellings: theo chiet tach - ((hanh doanh) OR (doanh doanh)) nhan khong cong ((manh toan) or (van toan)) tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chiet tach - ((hanh doanh) OR (doanh doanh)) nhan khong cong ((manh toan) OR (van toan)) tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chiet tach - ((hanh doanh) OR (doanh doanh)) nhan khong cong ((manh toan) or (van toan)) tap".
• Adding a wildcard symbol may retrieve word variants: theo chiet tach - ((hanh doanh) OR (doanh doanh)) nhan khong cong ((manh toan) or (van toan)) tap*.
