Perhaps you should try some spelling variations:
"philologist" » "philologica", "philologische", "philological"
"philologists" » "philologicas", "philologisches", "philologicals", "philological"
"philologisch" » "philologische", "philologica", "philosophisch"
"philologicas" » "philological", "philologica", "philologicis"
"philologies" » "philologien", "philologicis", "philologica", "philologys"
"philologiques" » "philologique", "philosophiques", "physiologiques"
"philologys" » "philology", "philologus", "philologos"
"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 "philologisch") OR (((("philologists" OR "philologicas") OR "philologiae") OR ((("philologies" OR "philologiques") OR "philologys") OR "philologie")) OR ((("philologies" OR "philologiques") OR "philologys") OR "philologie"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologist\" or \"philologisch\") or ((((\"philologists\" or \"philologicas\") or \"philologiae\") or (((\"philologies\" OR \"philologiques\") or \"philologys\") or \"philologie\")) or (((\"philologies\" OR \"philologiques\") or \"philologys\") or \"philologie\")))".
• Removing quotes may allow a broader search: (( philologist or philologisch ) or (((( philologists or philologicas ) or philologiae ) or ((( philologies OR philologiques ) or philologys ) or philologie )) or ((( philologies OR philologiques ) or philologys ) or philologie ))).
• Adding a wildcard symbol may retrieve word variants: (("philologist" or "philologisch") or (((("philologists" or "philologicas") or "philologiae") or ((("philologies" OR "philologiques") or "philologys") or "philologie")) or ((("philologies" OR "philologiques") or "philologys") or "philologie")))*.
