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