Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologica", "philologische"
"philologists" » "philologischs", "philologicas", "philologisches"
"philologischs" » "philologisch", "philologische", "philologischen"
"philological" » "philosophical"

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