Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philological"
"philologists" » "philologischs", "philologicals", "philological"
"philologica" » "philological", "philologisch", "philosophica"
"philologicals" » "philologicalls", "philologischls", "philosophicals", "philological", "philologically", "philologicae"
"philologicis" » "philological", "philosophicis", "philologisch"
"philologie" » "philology"
"philologischen" » "philologisch", "philosophischen", "philologischn", "philologicaln"
"philologische" » "philologisch", "philological"
"philosophische" » "philosophical", "philosophie"

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 "philologica") OR ((("philologists" OR ("philologicals" OR "philologicis")) OR ("philologiae" OR "philologie")) OR ("philologischen" OR ("philologische" OR "philosophische"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologist\" or \"philologica\") or (((\"philologists\" or (\"philologicals\" OR \"philologicis\")) or (\"philologiae\" or \"philologie\")) or (\"philologischen\" or (\"philologische\" or \"philosophische\"))))*".
• Removing quotes may allow a broader search: (( philologist or philologica ) or ((( philologists or ( philologicals OR philologicis )) or ( philologiae or philologie )) or ( philologischen or ( philologische or philosophische ))))*.
