Perhaps you should try some spelling variations:
"philologische" » "philosophische", "philologiae", "philological", "philologistse", "philologicae"
"philologisch" » "philologists", "philologica", "philosophisch"
"philologicas" » "philological", "philologica", "philologicis"
"philologies" » "philologien", "philologists", "philologicis"
"philologiques" » "philologique", "philosophiques", "physiologiques"

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