Perhaps you should try some spelling variations:
"philologica" » "philologisch", "philologische", "philosophica"
"philological" » "philologischl", "philologischel", "philosophical"
"philologie" » "philology"
"philologischs" » "philologisch", "philologische", "philologischen"

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