• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sang - thanh trung ((((cua tong) OR (cua cong))) or (cua thuong)) cong dan phan tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh trung ((((cua tong) OR (cua cong))) OR (cua thuong)) cong dan phan tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh trung ((((cua tong) OR (cua cong))) or (cua thuong)) cong dan phan tu*".
