• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sang - hanh trang ((cua truong) or (duong truong)) cong ngan ((hang cau) OR (hang ca))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh trang ((cua truong) OR (duong truong)) cong ngan ((hang cau) OR (hang ca))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - hanh trang ((cua truong) or (duong truong)) cong ngan ((hang cau) OR (hang ca))*".
