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

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