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