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