Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philologists", "philologica"
"philologischen" » "philologischeen", "philologistsen", "philologicaen", "philologische", "philosophischen"
"philological" » "philosophical"
"philologie" » "philology"

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