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