Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philological"
"philologists" » "philologischs", "philologicals", "philological"
"philologica" » "philological", "philologisch", "philosophica"
"philologische" » "philologisch", "philosophische", "philological"
"philologisches" » "philologischs", "philosophisches", "philologicals", "philologischen", "philologischer", "philologischem"
"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 "philologische")) 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 \"philologische\")) or (((\"philologists\" or \"philologisches\") or (\"philologiae\" or (\"philologie\" or \"philology\"))) or \"philologies\"))".
• Removing quotes may allow a broader search: (( philologist or ( philologica OR philologische )) or ((( philologists or philologisches ) or ( philologiae or ( philologie or philology ))) or philologies )).
• Adding a wildcard symbol may retrieve word variants: (("philologist" or ("philologica" OR "philologische")) or ((("philologists" or "philologisches") or ("philologiae" or ("philologie" or "philology"))) or "philologies"))*.
