Perhaps you should try some spelling variations:
"philologisch" » "philologists", "philologica", "philological"
"philologisches" » "philologistses", "philologicaes", "philologicales", "philologischen", "philologischer", "philologischem", "philosophisches", "philologicals", "philologistss"
"philologische" » "philologistse", "philologicae", "philologicale", "philosophische", "philological", "philologists"
"philosophisch" » "philosophische", "philosophischen", "philosophischer"
"philologies" » "philologien", "philologiques", "philologists", "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: (("philologiae" OR ("philologisch" OR "philosophisch")) OR ((("philologisches" OR "philologische") OR ("philologies" OR "philologie")) OR ("philologies" OR "philologie"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologiae\" or (\"philologisch\" OR \"philosophisch\")) or (((\"philologisches\" or \"philologische\") or (\"philologies\" or \"philologie\")) or (\"philologies\" or \"philologie\")))".
• Removing quotes may allow a broader search: (( philologiae or ( philologisch OR philosophisch )) or ((( philologisches or philologische ) or ( philologies or philologie )) or ( philologies or philologie ))).
• Adding a wildcard symbol may retrieve word variants: (("philologiae" or ("philologisch" OR "philosophisch")) or ((("philologisches" or "philologische") or ("philologies" or "philologie")) or ("philologies" or "philologie")))*.
