Perhaps you should try some spelling variations:
"philologische" » "philologisch", "philologists"
"philosophische" » "philosophical", "philosophie"
"philological" » "philosophical", "philologischl", "philologistsl"
"philologicals" » "philosophicals", "philologically", "philologicis", "philologicae", "philologischls", "philologistsls"
"philologica" » "philologisch", "philosophica", "philologists"
"philologie" » "philology"
"philologiques" » "philologies", "philosophiques", "physiologiques", "biologiques"
"philologique" » "philosophique", "physiologique", "biologique"

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: (("philologische" OR "philosophische") OR (((("philological" OR "philologicals") OR "philologica") OR ("philologiae" OR "philologie")) OR ("philologiques" OR "philologique"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologische\" OR \"philosophische\") or ((((\"philological\" or \"philologicals\") or \"philologica\") or (\"philologiae\" or \"philologie\")) or (\"philologiques\" or \"philologique\")))".
• Removing quotes may allow a broader search: (( philologische OR philosophische ) or (((( philological or philologicals ) or philologica ) or ( philologiae or philologie )) or ( philologiques or philologique ))).
• Adding a wildcard symbol may retrieve word variants: (("philologische" OR "philosophische") or (((("philological" or "philologicals") or "philologica") or ("philologiae" or "philologie")) or ("philologiques" or "philologique")))*.
