• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"johannes pfister muller\") OR (\"johannes pfisters muhle\"))) or (((\"johannes peter muller\") or (\"johann peter muller\"))))".
• Removing quotes may allow a broader search: (((( johannes pfister muller ) OR ( johannes pfisters muhle ))) or ((( johannes peter muller ) or ( johann peter muller )))).
• Adding a wildcard symbol may retrieve word variants: (((("johannes pfister muller") OR ("johannes pfisters muhle"))) or ((("johannes peter muller") or ("johann peter muller"))))*.
