Perhaps you should try some spelling variations:
"philologica" » "philological", "philologie", "philosophica"
"philologiae" » "philologie"
"philologists" » "philologie", "philological"
"philologies" » "philologie", "philologiques", "philologicis"
"philologien" » "philologie", "philologen", "philologist"
"philologisch" » "philosophisch", "philologie", "philological"
"philologischen" » "philosophischen", "philologieen", "philologicalen", "philologien", "philologicaln"
"philologische" » "philosophische", "philologiee", "philologicale", "philologie", "philological"
"philosophischen" » "philosophische"

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 (("philologists" OR ("philologies" OR "philologien")) OR ("philologisch" OR (("philologischen" OR "philologische") OR "philosophischen")))).
• Removing quotes may allow a broader search: (( philologica or philologiae ) or (( philologists or ( philologies or philologien )) or ( philologisch or (( philologischen or philologische ) or philosophischen )))).
• Adding a wildcard symbol may retrieve word variants: (("philologica" or "philologiae") or (("philologists" or ("philologies" or "philologien")) or ("philologisch" or (("philologischen" or "philologische") or "philosophischen"))))*.
