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