Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologische", "philological"
"philologists" » "philologischs", "philologisches", "philologicals", "philological"
"philologica" » "philological", "philologisch", "philologische"
"philologicas" » "philologicals", "philologischs", "philologisches", "philological", "philologicis", "philologicae"
"philologischs" » "philologisch", "philologische", "philologischen"
"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 "philologica") OR (("philologischs" OR ("philologiae" OR "philologie")) OR ("philologists" OR "philologicas"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologist\" OR \"philologica\") or ((\"philologischs\" or (\"philologiae\" or \"philologie\")) or (\"philologists\" or \"philologicas\")))".
• Removing quotes may allow a broader search: (( philologist OR philologica ) or (( philologischs or ( philologiae or philologie )) or ( philologists or philologicas ))).
• Adding a wildcard symbol may retrieve word variants: (("philologist" OR "philologica") or (("philologischs" or ("philologiae" or "philologie")) or ("philologists" or "philologicas")))*.
