Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philologists", "philologica"
"philologischer" » "philologischeer", "philologistser", "philologicaer", "philologische", "philologischen", "philosophischer"
"philological" » "philosophical", "philologie"
"philologiae" » "philologie"

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: ("philologisch" OR ((("philologischer" OR ("philological" OR "philologiae")) OR "philology") OR "philology")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"philologisch\" or (((\"philologischer\" or (\"philological\" OR \"philologiae\")) or \"philology\") or \"philology\"))".
• Removing quotes may allow a broader search: ( philologisch or ((( philologischer or ( philological OR philologiae )) or philology ) or philology )).
• Adding a wildcard symbol may retrieve word variants: ("philologisch" or ((("philologischer" or ("philological" OR "philologiae")) or "philology") or "philology"))*.
