Perhaps you should try some spelling variations:
philologische » philologisch, philosophische, philological
philologischen » philologischn, philosophischen, philologicaln, philologisch
philologie » philology
philologischs » philologisch, philologischer, philologischem
philologicaln » philological, philologically, philologica

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: (( philologische OR (philologiae OR philologie) ) OR (philologischs OR (philologischen OR philologicaln)) ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( philologische or (philologiae or philologie) ) or (philologischs or (philologischen OR philologicaln)) )".
• Adding a wildcard symbol may retrieve word variants: (( philologische or (philologiae or philologie) ) or (philologischs or (philologischen OR philologicaln)) )*.
