Perhaps you should try some spelling variations:
"philologist" » "philologie", "philologica", "philologische"
"philologists" » "philologies", "philologicas", "philologisches", "philologie", "philological"
"philologisch" » "philologische", "philologica", "philosophisch"
"philologicis" » "philological", "philologica", "philologische"
"philologiques" » "philologies", "philosophiques", "physiologiques", "philologisches"
"philologique" » "philologie", "philosophique", "philologische"
"philologiae" » "philologie"

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