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