Perhaps you should try some spelling variations:
"philologist" » "philologica", "philologische", "philological"
"philologists" » "philologicas", "philologisches", "philologicals", "philological"
"philologisch" » "philologische", "philologica", "philosophisch"
"philologie" » "philology"
"philologies" » "philologys", "philologien", "philologica", "philologen"
"philologiques" » "philologique", "physiologiques", "biologiques"
"philosophiques" » "philosophique", "philosophies", "philosophie"
"philologicis" » "philological", "philologica", "philologische"

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