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