Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologische"
"philologists" » "philologischs", "philologisches"
"philologica" » "philologisch", "philologische"
"philological" » "philologischl", "philologischel"
"philosophical" » "philosophicl", "philosophial", "philosophischl"
"philosophica" » "philosophic", "philosophia", "philosophisch"
"philologies" » "philologien", "philologiques", "philologicis"

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