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