Perhaps you should try some spelling variations:
"philologisch" » "philologica", "philosophisch", "philological"
"philologische" » "philologicae", "philosophische", "philologicale", "philological", "philologica"
"philologists" » "philological"
"philologies" » "philologien", "philologiques", "philologicis", "philologys"
"philologie" » "philology"

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