Perhaps you should try some spelling variations:
"philological" » "philologiae", "philosophical", "philologie"
"philologischen" » "philologische", "philosophischen", "philologischeen", "philologistsen", "philologicaen"
"philologisch" » "philologische", "philologists", "philologica"

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: ("philological" OR ("philologischen" OR ("philologischen" OR "philologisch"))).
• Removing quotes may allow a broader search: ( philological or ( philologischen or ( philologischen or philologisch ))).
• Adding a wildcard symbol may retrieve word variants: ("philological" or ("philologischen" or ("philologischen" or "philologisch")))*.
