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

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