Perhaps you should try some spelling variations:
philologica » philologie, philologiae, philosophica
philological » philologiel, philologiael, philosophical, philologiae, philologie
philologisch » philologists, philosophisch, philologie
philologische » philologistse, philosophische, philologiee, philologie, philologiae

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: (((philologica OR philologisch) OR philological) OR philologische).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((philologica OR philologisch) or philological) or philologische)".
• Adding a wildcard symbol may retrieve word variants: (((philologica OR philologisch) or philological) or philologische)*.
