• Performing a fuzzy search may retrieve terms with similar spellings: doi ((chieu xanh) or (trieu tinh)) - nhan dang luan dong cong ((san toan) OR (van toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (trieu tinh)) - nhan dang luan dong cong ((san toan) OR (van toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (trieu tinh)) - nhan dang luan dong cong ((san toan) OR (van toan)) cau".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (trieu tinh)) - nhan dang luan dong cong ((san toan) OR (van toan)) cau*.
