Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologie", "philologiae"
"philologists" » "philologischs", "philologies", "philologiaes", "philologie", "philologiae", "philological"
"philosophisch" » "philosophische", "philosophischer", "philosophical"
"philosophischen" » "philosophischeen", "philosophischeren", "philosophicalen", "philosophische"
"philologicas" » "philological", "philologica", "philologicae"
"philologicis" » "philological", "philologica", "philologische"
"philologiques" » "philologies", "philosophiques", "physiologiques", "philologiaes"
"philologique" » "philologie", "philologiae", "philosophique"

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