Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologische", "philological"
"philologists" » "philologischs", "philologisches", "philologicals", "philological"
"philologica" » "philological", "philologisch", "philologische"
"philologicas" » "philologicals", "philologischs", "philologisches", "philological", "philologicis", "philologicae"
"philologie" » "philology"
"philologisches" » "philologische", "philologischen", "philologischer"

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