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