Perhaps you should try some spelling variations:
"philologist" » "philologiae", "philologica", "philologische"
"philologists" » "philologiaes", "philologicas", "philologisches", "philologiae", "philological"
"philologie" » "philology"
"philologischs" » "philologische", "philologischer", "philologischem", "philologisches", "philologicas", "philosophischs"
"philologisch" » "philologische", "philologica", "philosophisch"
"philologischen" » "philologischeen", "philologicaen", "philosophischen", "philologische"
"philosophischen" » "philosophische"

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 "philologie") OR ("philologists" OR (("philologischs" OR "philologisch") OR ("philologischen" OR "philosophischen")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologist\" or \"philologie\") or (\"philologists\" or ((\"philologischs\" OR \"philologisch\") or (\"philologischen\" or \"philosophischen\"))))".
• Removing quotes may allow a broader search: (( philologist or philologie ) or ( philologists or (( philologischs OR philologisch ) or ( philologischen or philosophischen )))).
• Adding a wildcard symbol may retrieve word variants: (("philologist" or "philologie") or ("philologists" or (("philologischs" OR "philologisch") or ("philologischen" or "philosophischen"))))*.
