Perhaps you should try some spelling variations:
"philologica" » "philological", "philologisch", "philologische"
"philosophisch" » "philosophische", "philosophischen", "philosophischer"
"philologie" » "philology"
"philologists" » "philological"
"philologisches" » "philologische", "philologischen", "philologischer"

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: (((("philologica" OR "philosophisch") OR "philologiae") OR "philologie") OR ("philologists" OR "philologisches")).
• Removing quotes may allow a broader search: (((( philologica or philosophisch ) or philologiae ) or philologie ) or ( philologists or philologisches )).
• Adding a wildcard symbol may retrieve word variants: (((("philologica" or "philosophisch") or "philologiae") or "philologie") or ("philologists" or "philologisches"))*.
