Perhaps you should try some spelling variations:
"philologist" » "philologie", "philologiae", "philologica"
"philologists" » "philologies", "philologiaes", "philologicas", "philologie", "philologiae"
"philologisch" » "philologische", "philologica", "philosophisch"
"philological" » "philologiae", "philosophical", "philologie"
"philologicas" » "philologica", "philologicae", "philologicus"
"philologicis" » "philologica", "philologische", "philosophicis"
"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 "philologisch") OR (((("philologists" OR "philological") 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 \"philologisch\") or ((((\"philologists\" OR \"philological\") or \"philologicas\") or (\"philologicis\" or (\"philologiques\" or \"philologique\"))) or (\"philologicis\" or (\"philologiques\" or \"philologique\"))))".
• Removing quotes may allow a broader search: (( philologist or philologisch ) or (((( philologists OR philological ) or philologicas ) or ( philologicis or ( philologiques or philologique ))) or ( philologicis or ( philologiques or philologique )))).
• Adding a wildcard symbol may retrieve word variants: (("philologist" or "philologisch") or (((("philologists" OR "philological") or "philologicas") or ("philologicis" or ("philologiques" or "philologique"))) or ("philologicis" or ("philologiques" or "philologique"))))*.
