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

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