Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philologists", "philologica"
"philologisches" » "philologischees", "philologistses", "philologicaes", "philologische", "philologischen", "philologischer"
"philologien" » "philologen", "philologica", "philologist", "philologyn"
"philologyn" » "philology", "philologen", "philologin"
"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 (("philologisches" OR (("philologien" OR "philologyn") OR "philologie")) OR (("philologien" OR "philologyn") OR "philologie"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologiae\" or \"philologisch\") or ((\"philologisches\" or ((\"philologien\" OR \"philologyn\") or \"philologie\")) or ((\"philologien\" OR \"philologyn\") or \"philologie\")))".
• Removing quotes may allow a broader search: (( philologiae or philologisch ) or (( philologisches or (( philologien OR philologyn ) or philologie )) or (( philologien OR philologyn ) or philologie ))).
• Adding a wildcard symbol may retrieve word variants: (("philologiae" or "philologisch") or (("philologisches" or (("philologien" OR "philologyn") or "philologie")) or (("philologien" OR "philologyn") or "philologie")))*.
