Perhaps you should try some spelling variations:
"philologica" » "philological", "philologiae", "philologische"
"philologisch" » "philologische", "philosophisch", "philologiae"
"philologists" » "philologiae", "philological"
"philologies" » "philologiques", "philologicis", "philologiae", "philologys"
"philologien" » "philologen", "philologiae", "philologist", "philologyn"
"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: (("philologica" OR "philologisch") OR (("philologists" OR (("philologies" OR "philologien") OR "philologie")) OR (("philologies" OR "philologien") OR "philologie"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologica\" or \"philologisch\") or ((\"philologists\" or ((\"philologies\" OR \"philologien\") or \"philologie\")) or ((\"philologies\" OR \"philologien\") or \"philologie\")))".
• Removing quotes may allow a broader search: (( philologica or philologisch ) or (( philologists or (( philologies OR philologien ) or philologie )) or (( philologies OR philologien ) or philologie ))).
• Adding a wildcard symbol may retrieve word variants: (("philologica" or "philologisch") or (("philologists" or (("philologies" OR "philologien") or "philologie")) or (("philologies" OR "philologien") or "philologie")))*.
