• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chiet) OR (ho thiet)) tach - thanh tung cac ((thuong cong) or (thuong dong)) dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chiet) OR (ho thiet)) tach - thanh tung cac ((thuong cong) OR (thuong dong)) dan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chiet) OR (ho thiet)) tach - thanh tung cac ((thuong cong) or (thuong dong)) dan toan cao*".
