• Removing quotes may allow a broader search: (((((( specimen philologica slavicae ) OR ( specimen philologie slave ))) OR ( specimens philological slavicae ))) OR ( specimen philosophiae publice )).
• Adding a wildcard symbol may retrieve word variants: (((((("specimen philologica slavicae") OR ("specimen philologie slave"))) OR ("specimens philological slavicae"))) OR ("specimen philosophiae publice"))*.
