Perhaps you should try some spelling variations:
"philosophische" » "philosophical", "philosophie"
"philological" » "philosophical", "philologischl", "philologischel"
"philologica" » "philologisch", "philologische", "philosophica"
"philologie" » "philology"

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: (((("philosophische" OR "philological") OR "philologica") OR "philologiae") OR ("philologists" OR "philologie")).
• Removing quotes may allow a broader search: (((( philosophische or philological ) or philologica ) or philologiae ) or ( philologists or philologie )).
• Adding a wildcard symbol may retrieve word variants: (((("philosophische" or "philological") or "philologica") or "philologiae") or ("philologists" or "philologie"))*.
