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

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