Perhaps you should try some spelling variations:
"philologie" » "philology"
"philologisch" » "philologische", "philologica", "philosophisch"
"philologists" » "philologiae"
"philosophica" » "philosophical", "philosophic", "philosophia"
"philological" » "philologiae", "philosophical"

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