Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologiae", "philologica"
"philologists" » "philologischs", "philologiaes", "philologicas", "philologiae", "philological"
"philologisches" » "philologische", "philologischen", "philologischer"
"philologys" » "philologus", "philologos", "philologis"

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