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