• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (doi chi)) xanh - thanh trung phan ((xuong huong) OR (muong khuong)) van toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chi)) xanh - thanh trung phan ((xuong huong) OR (muong khuong)) van toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chi)) xanh - thanh trung phan ((xuong huong) OR (muong khuong)) van toan cau*".
