Perhaps you should try some spelling variations:
"philologist" » "philologie", "philologiae", "philologica"
"philologists" » "philologies", "philologiaes", "philologicas", "philologie", "philologiae", "philological"
"philologisch" » "philologica", "philosophisch", "philologie"
"philologischs" » "philologicas", "philosophischs", "philologies", "philologischer", "philologischem", "philologicis"
"philologischen" » "philologicaen", "philosophischen", "philologieen", "philologien", "philologiaen"
"philologische" » "philologicae", "philosophische", "philologiee", "philologie", "philologiae"
"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 "philologisch") OR ("philologists" OR ("philologischs" OR (("philologischen" OR "philologische") OR "philosophischen"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologist\" or \"philologisch\") or (\"philologists\" or (\"philologischs\" or ((\"philologischen\" OR \"philologische\") or \"philosophischen\"))))*".
• Removing quotes may allow a broader search: (( philologist or philologisch ) or ( philologists or ( philologischs or (( philologischen OR philologische ) or philosophischen ))))*.
