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