• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"specimen philosophiae slavicae\") OR (\"specimen philosophiae suae\"))) or (((\"specimens philosophiae publice\") or (\"specimens philologica slavicae\"))))".
• Removing quotes may allow a broader search: (((( specimen philosophiae slavicae ) OR ( specimen philosophiae suae ))) or ((( specimens philosophiae publice ) or ( specimens philologica slavicae )))).
• Adding a wildcard symbol may retrieve word variants: (((("specimen philosophiae slavicae") OR ("specimen philosophiae suae"))) or ((("specimens philosophiae publice") or ("specimens philologica slavicae"))))*.
