Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologische"
"philologists" » "philologischs", "philologisches"
"philologica" » "philologisch", "philologische", "philosophica"
"philological" » "philologischl", "philologischel", "philosophical"
"philologisches" » "philologische", "philologischen", "philologischer"
"philologies" » "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: (("philologist" OR ("philologica" OR "philological")) OR ((("philologists" OR "philologisches") OR ("philologiae" OR ("philologie" OR "philology"))) OR "philologies")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologist\" or (\"philologica\" or \"philological\")) or (((\"philologists\" or \"philologisches\") or (\"philologiae\" or (\"philologie\" OR \"philology\"))) or \"philologies\"))".
• Removing quotes may allow a broader search: (( philologist or ( philologica or philological )) or ((( philologists or philologisches ) or ( philologiae or ( philologie OR philology ))) or philologies )).
• Adding a wildcard symbol may retrieve word variants: (("philologist" or ("philologica" or "philological")) or ((("philologists" or "philologisches") or ("philologiae" or ("philologie" OR "philology"))) or "philologies"))*.
