Perhaps you should try some spelling variations:
"philological" » "philosophical", "philologischel"
"philologie" » "philology"
"philologica" » "philologische", "philosophica"
"philologischs" » "philologische", "philologischen", "philologischer", "philologisches", "philosophischs"
"philologisch" » "philologische", "philosophisch"

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