• If you are trying to use Boolean operators, they must be ALL CAPS: (((("specimina philologica slavicae") OR ("specimina philologica slavica"))) OR ((("specimen philosophiae slavicae") OR ("specimen philologiae slavicae")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"specimina philologica slavicae\") or (\"specimina philologica slavica\"))) or (((\"specimen philosophiae slavicae\") OR (\"specimen philologiae slavicae\"))))".
• Removing quotes may allow a broader search: (((( specimina philologica slavicae ) or ( specimina philologica slavica ))) or ((( specimen philosophiae slavicae ) OR ( specimen philologiae slavicae )))).
• Adding a wildcard symbol may retrieve word variants: (((("specimina philologica slavicae") or ("specimina philologica slavica"))) or ((("specimen philosophiae slavicae") OR ("specimen philologiae slavicae"))))*.
