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