Perhaps you should try some spelling variations:
"philologische" » "philologisch", "philosophische", "philologica"
"philological" » "philosophical"
"philologischs" » "philologisch", "philologischen", "philologischer"
"philologie" » "philology"
"philologies" » "philologys", "philologien", "philologiques", "philologicis"

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