Perhaps you should try some spelling variations:
"philologica" » "philologisch", "philologiae", "philologists"
"philological" » "philologischl", "philologiael", "philologistsl", "philologiae", "philosophical"
"philosophica" » "philosophical", "philosophic", "philosophia"
"philologische" » "philologisch", "philosophische", "philologiae"

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