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