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