Perhaps you should try some spelling variations:
"philological" » "philosophical", "philologischl", "philologischel"
"philologie" » "philology"
"philologica" » "philologisch", "philologische"
"philosophica" » "philosophical", "philosophic", "philosophia"
"philologischs" » "philologisch", "philologische", "philologischen"

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