Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philosophisch", "philological"
"philologica" » "philological", "philologische"
"philosophica" » "philosophical", "philosophia", "philosophisch", "philosophiea", "philosophicala", "philosophischa"
"philosophic" » "philosophie", "philosophical", "philosophisch"
"philologists" » "philological"
"philologie" » "philology"
"philologies" » "philologys", "philologien", "philologiques", "philologicis"

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: (("philologisch" OR ("philologica" OR ("philosophica" OR "philosophic"))) OR (("philologists" OR ("philologiae" OR "philologie")) OR "philologies")).
• Removing quotes may allow a broader search: (( philologisch or ( philologica or ( philosophica or philosophic ))) or (( philologists or ( philologiae or philologie )) or philologies )).
• Adding a wildcard symbol may retrieve word variants: (("philologisch" or ("philologica" or ("philosophica" or "philosophic"))) or (("philologists" or ("philologiae" or "philologie")) or "philologies"))*.
