Perhaps you should try some spelling variations:
"philologica" » "philological", "philologiae", "philologische"
"philologisch" » "philologische", "philosophisch", "philologiae"
"philologists" » "philologiae", "philological"
"philologies" » "philologien", "philologiques", "philologicis", "philologys"
"philologie" » "philology"

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