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

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 (("philologica" OR ("philosophica" OR "philosophia")) OR "philologische"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"philologie\" or ((\"philologica\" or (\"philosophica\" OR \"philosophia\")) or \"philologische\"))*".
• Removing quotes may allow a broader search: ( philologie or (( philologica or ( philosophica OR philosophia )) or philologische ))*.
