Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philosophisch", "philologie"
"philologica" » "philological", "philologie", "philologische"
"philologists" » "philologie", "philological"
"philologiae" » "philologie"
"philologien" » "philologie", "philologen", "philologist"

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