Perhaps you should try some spelling variations:
philological polemical » philological philomedical, philosophical political, philological critical
philological slavicae » philologica slavicae, philologiae slavicae, philological satirical
slavicae » slavice
slavica » slavic

You may be able to get more results by adjusting your search query.

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