Perhaps you should try some spelling variations:
"philosophisch" » "philosophische", "philosophischen", "philosophischer"
"philologica" » "philologische"
"philological" » "philologischel", "philosophical"
"philologisch" » "philologische"
"philosophica" » "philosophical", "philosophic", "philosophia"
"philologie" » "philology"
"philologies" » "philologys", "philologien", "philologiques", "philologicis"

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