Perhaps you should try some spelling variations:
"philologica" » "philological", "philologische", "philosophica"
"philologisch" » "philologische", "philosophisch", "philological"
"philologischen" » "philologischeen", "philosophischen", "philologicalen", "philologische"
"philologie" » "philology"
"philologists" » "philological"

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