Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philologists", "philologica"
"philological" » "philologiae", "philosophical", "philologie"
"philosophisch" » "philosophische", "philosophischen", "philosophischer"

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