Perhaps you should try some spelling variations:
"philologica" » "philologische", "philosophica"
"philological" » "philologischel", "philosophical"
"philologisch" » "philologische", "philosophisch"
"philologie" » "philology"
"philologien" » "philologyn", "philologen", "philologist", "philologischen"

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 "philological") OR "philologisch") OR (("philologists" OR ("philologiae" OR "philologie")) OR "philologien")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"philologica\" OR \"philological\") or \"philologisch\") or ((\"philologists\" or (\"philologiae\" or \"philologie\")) or \"philologien\"))".
• Removing quotes may allow a broader search: ((( philologica OR philological ) or philologisch ) or (( philologists or ( philologiae or philologie )) or philologien )).
• Adding a wildcard symbol may retrieve word variants: ((("philologica" OR "philological") or "philologisch") or (("philologists" or ("philologiae" or "philologie")) or "philologien"))*.
