Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologica", "philological"
"philologists" » "philologischs", "philologicas", "philologicals", "philological"
"philologische" » "philologisch", "philosophische", "philological"
"philologischs" » "philologisch", "philologischen", "philologischer"
"philologie" » "philology"

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