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