Perhaps you should try some spelling variations:
"philologist" » "philologists", "philologie", "philologiae"
"philologisch" » "philologists", "philologie", "philologiae"
"philologische" » "philologistse", "philologiee", "philologiaee", "philologie", "philologiae", "philologists"
"philologica" » "philologie", "philologiae", "philosophica"
"philological" » "philologiel", "philologiael", "philosophical", "philologiae", "philologie"
"philosophisch" » "philosophischen", "philosophischer", "philosophical"
"philosophische" » "philosophischene", "philosophischere", "philosophicale", "philosophical", "philosophie"

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