• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"hinrich hinz\") OR (\"hsinrich hsinz\"))) OR (((\"heinrich hein\") OR (\"hsinrich hsin\"))))".
• Removing quotes may allow a broader search: (((( hinrich hinz ) OR ( hsinrich hsinz ))) OR ((( heinrich hein ) OR ( hsinrich hsin )))).
• Adding a wildcard symbol may retrieve word variants: (((("hinrich hinz") OR ("hsinrich hsinz"))) OR ((("heinrich hein") OR ("hsinrich hsin"))))*.
