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