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