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