Perhaps you should try some spelling variations:
"philologica" » "philological", "philologiae", "philologische"
"philologisch" » "philologische", "philosophisch", "philologiae"
"philologists" » "philologiae", "philological"
"philologies" » "philologien", "philologiques", "philologicis"

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