Perhaps you should try some spelling variations:
"philologisch" » "philologists", "philologica", "philosophisch"
"philologische" » "philologistse", "philologicae", "philosophische", "philologiae", "philologists"
"philological" » "philologiae", "philosophical"
"philologys" » "philology", "philologus", "philologos"
"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: (("philologisch" OR "philologische") OR (("philological" OR ("philologys" OR "philologie")) OR ("philologys" OR "philologie"))).
• Removing quotes may allow a broader search: (( philologisch or philologische ) or (( philological or ( philologys or philologie )) or ( philologys or philologie ))).
• Adding a wildcard symbol may retrieve word variants: (("philologisch" or "philologische") or (("philological" or ("philologys" or "philologie")) or ("philologys" or "philologie")))*.
