Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philosophisch", "philological"
"philologica" » "philological", "philologische", "philosophica"
"philologists" » "philological"
"philologie" » "philology"
"philologies" » "philologys", "philologien", "philologiques", "philologicis"

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