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