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

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