Perhaps you should try some spelling variations:
"philologica" » "philologiae", "philologische", "philosophica"
"philological" » "philologiael", "philologischel", "philosophical", "philologiae"
"philologisch" » "philologische", "philosophisch", "philologiae"
"philologists" » "philologiae"
"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 "philological") 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 \"philological\") 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 philological ) or (( philologies OR philologie ) or philology )) or (( philologies OR philologie ) or philology )))*.
