• If you are trying to use Boolean operators, they must be ALL CAPS: (((("specimen philosophiae suae") OR ("specimen philosophiae publice"))) OR ((((("specimens philosophiae slavicae") OR ("species philosophers slavicae"))) OR ("specimina philologica slavicae"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"specimen philosophiae suae\") or (\"specimen philosophiae publice\"))) or (((((\"specimens philosophiae slavicae\") OR (\"species philosophers slavicae\"))) or (\"specimina philologica slavicae\"))))*".
• Removing quotes may allow a broader search: (((( specimen philosophiae suae ) or ( specimen philosophiae publice ))) or ((((( specimens philosophiae slavicae ) OR ( species philosophers slavicae ))) or ( specimina philologica slavicae ))))*.
