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