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

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