• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"joshua alexander sowie\") OR (((\"jahn alexander si\") OR (\"john alexander m\"))))~".
• Removing quotes may allow a broader search: (( joshua alexander sowie ) OR ((( jahn alexander si ) OR ( john alexander m ))))~.
• Adding a wildcard symbol may retrieve word variants: (("joshua alexander sowie") OR ((("jahn alexander si") OR ("john alexander m"))))*.
