Perhaps you should try some spelling variations:
"philologist" » "philologiae", "philologische", "philological"
"philologists" » "philologiaes", "philologisches", "philologicals", "philologiae", "philological"
"philologisch" » "philologische", "philosophisch", "philologiae"
"philologie" » "philology"
"philologies" » "philologys", "philologiques", "philologicis", "philologiae"
"philologien" » "philologyn", "philologen", "philologiae", "philologischen"
"philologicas" » "philological", "philologicis", "philologicae", "philologicals", "philologiaes", "philologisches"
"philologica" » "philological", "philologiae", "philologische"
"philologys" » "philology", "philologus", "philologos"

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