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