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

"philologiques" » "philologies", "philosophiques", "physiologiques", "philologiaes", "philologisches"
"philologique" » "philologiae", "philosophique", "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 ("philosophisch" OR "philosophischen")) OR ((("philologists" OR "philologicas") OR ("philologicis" OR ("philologiques" OR ("philologique" OR "philologie")))) OR ("philologicis" OR ("philologiques" OR ("philologique" OR "philologie"))))).
• 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 \"philologie\")))) or (\"philologicis\" or (\"philologiques\" or (\"philologique\" OR \"philologie\")))))".
• Removing quotes may allow a broader search: (( philologist or ( philosophisch or philosophischen )) or ((( philologists or philologicas ) or ( philologicis or ( philologiques or ( philologique OR philologie )))) or ( philologicis or ( philologiques or ( philologique OR philologie ))))).
• Adding a wildcard symbol may retrieve word variants: (("philologist" or ("philosophisch" or "philosophischen")) or ((("philologists" or "philologicas") or ("philologicis" or ("philologiques" or ("philologique" OR "philologie")))) or ("philologicis" or ("philologiques" or ("philologique" OR "philologie")))))*.
