• Performing a fuzzy search may retrieve terms with similar spellings: (("thang chien chong my") or ((("thanh hien chong my") OR ("thanh hien cong my"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("thang chien chong my") OR ((("thanh hien chong my") OR ("thanh hien cong my")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thang chien chong my\") or (((\"thanh hien chong my\") OR (\"thanh hien cong my\"))))".
• Removing quotes may allow a broader search: (( thang chien chong my ) or ((( thanh hien chong my ) OR ( thanh hien cong my )))).
• Adding a wildcard symbol may retrieve word variants: (("thang chien chong my") or ((("thanh hien chong my") OR ("thanh hien cong my"))))*.
