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