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