Perhaps you should try some spelling variations:
"philologist" » "philologie", "philologica", "philologische"
"philologists" » "philologies", "philologicas", "philologisches", "philologie", "philological"
"philologisch" » "philologische", "philologica", "philosophisch"
"philologicas" » "philological", "philologica", "philologicis"
"philologies" » "philologie", "philologiques", "philologicis"
"philologien" » "philologie", "philologen", "philologica"
"philologiae" » "philologie"

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 "philologicas") OR "philologicas") OR ("philologies" OR ("philologien" OR "philologiae"))) OR ("philologies" OR ("philologien" OR "philologiae")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologist\" or \"philologisch\") or ((((\"philologists\" or \"philologicas\") or \"philologicas\") or (\"philologies\" or (\"philologien\" OR \"philologiae\"))) or (\"philologies\" or (\"philologien\" OR \"philologiae\"))))".
• Removing quotes may allow a broader search: (( philologist or philologisch ) or (((( philologists or philologicas ) or philologicas ) or ( philologies or ( philologien OR philologiae ))) or ( philologies or ( philologien OR philologiae )))).
• Adding a wildcard symbol may retrieve word variants: (("philologist" or "philologisch") or (((("philologists" or "philologicas") or "philologicas") or ("philologies" or ("philologien" OR "philologiae"))) or ("philologies" or ("philologien" OR "philologiae"))))*.
