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