• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"specimen philosophiae slavicae\") or (\"specimen philosophiae publice\"))) or (((((\"specimens philosophiae slavicae\") OR (\"specimens philologiae slavicae\"))) or (\"specimina philologica slavicae\"))))*".
• Removing quotes may allow a broader search: (((( specimen philosophiae slavicae ) or ( specimen philosophiae publice ))) or ((((( specimens philosophiae slavicae ) OR ( specimens philologiae slavicae ))) or ( specimina philologica slavicae ))))*.
