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