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