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