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