Perhaps you should try some spelling variations:
"philologist" » "philologists"
"philologica" » "philologists"
"philological" » "philologistsl", "philosophical"
"philosophica" » "philosophical", "philosophic", "philosophia"
"philologie" » "philology"
"philologisch" » "philologists", "philosophisch"
"philologischen" » "philologistsen", "philosophischen", "philologistsn"
"philologische" » "philologistse", "philosophische", "philologists"
"philosophischen" » "philosophische"

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