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

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: (("philologists" OR ("philosophical" OR "philosophischen")) OR ("philologische" OR "philosophisches")).
• Removing quotes may allow a broader search: (( philologists or ( philosophical or philosophischen )) or ( philologische or philosophisches )).
• Adding a wildcard symbol may retrieve word variants: (("philologists" or ("philosophical" or "philosophischen")) or ("philologische" or "philosophisches"))*.
