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