Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philologists", "philologica"
"philologisches" » "philologischees", "philologistses", "philologicaes", "philologische", "philologischen", "philologischer"
"philologien" » "philologen", "philologica", "philologist", "philologyn"
"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: (("philologiae" OR "philologisch") OR (("philologisches" OR ("philologien" OR "philologie")) OR ("philologien" OR "philologie"))).
• Removing quotes may allow a broader search: (( philologiae or philologisch ) or (( philologisches or ( philologien or philologie )) or ( philologien or philologie ))).
• Adding a wildcard symbol may retrieve word variants: (("philologiae" or "philologisch") or (("philologisches" or ("philologien" or "philologie")) or ("philologien" or "philologie")))*.
