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