• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"m friedrich goerdeler\") OR (((\"la friedrich goerdeler\") OR (\"glogau friedrich goerdeler\"))))~".
• Removing quotes may allow a broader search: (( m friedrich goerdeler ) OR ((( la friedrich goerdeler ) OR ( glogau friedrich goerdeler ))))~.
• Adding a wildcard symbol may retrieve word variants: (("m friedrich goerdeler") OR ((("la friedrich goerdeler") OR ("glogau friedrich goerdeler"))))*.
