Perhaps you should try some spelling variations:
"philological" » "philosophical"
"philologien" » "philologen", "philologica", "philologist", "philologyn"
"philologie" » "philology"
"philologies" » "philologys", "philologiques", "philologicis", "philologica"

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