Perhaps you should try some spelling variations:
"philologica" » "philological", "philologisch", "philologie"
"philosophisch" » "philosophische", "philosophischer", "philosophical"
"philosophischen" » "philosophischeen", "philosophischeren", "philosophicalen", "philosophische"
"philologists" » "philologie", "philologiae", "philological"
"philologies" » "philologie", "philologiques", "philologicis"
"philologien" » "philologie", "philologen", "philologiae"

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