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