Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologische"
"philologists" » "philologischs", "philologisches"
"philological" » "philosophical", "philologischl", "philologischel"
"philologica" » "philologisch", "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: (((("philologist" OR "philological") OR "philologica") OR ("philologiae" OR "philologie")) OR (("philologists" OR "philology") OR "philology")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"philologist\" OR \"philological\") or \"philologica\") or (\"philologiae\" or \"philologie\")) or ((\"philologists\" or \"philology\") or \"philology\"))".
• Removing quotes may allow a broader search: (((( philologist OR philological ) or philologica ) or ( philologiae or philologie )) or (( philologists or philology ) or philology )).
• Adding a wildcard symbol may retrieve word variants: (((("philologist" OR "philological") or "philologica") or ("philologiae" or "philologie")) or (("philologists" or "philology") or "philology"))*.
