• If you are trying to use Boolean operators, they must be ALL CAPS: (("johannes pfister muller") OR ((("johannes peter muller") OR ("johann peter muller"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"johannes pfister muller\") or (((\"johannes peter muller\") OR (\"johann peter muller\"))))*".
• Removing quotes may allow a broader search: (( johannes pfister muller ) or ((( johannes peter muller ) OR ( johann peter muller ))))*.
