Perhaps you should try some spelling variations:
"philologist" » "philologiae", "philologica", "philologische"
"philologists" » "philologiaes", "philologicas", "philologisches", "philologiae", "philological"
"philologisch" » "philologische", "philologica", "philologiae"
"philosophisch" » "philosophische", "philosophischen", "philosophischer"

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