Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philologie", "philologiae"
"philologica" » "philological", "philologie", "philologiae"
"philologists" » "philologie", "philologiae", "philological"
"philosophisch" » "philosophische", "philosophischen", "philosophischer"

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