At least using surfraw, the duckduckgo.elvi either doesn't make provision for and/or doesn't pass the negative filter option through with google directly you can use the - operator in front of a term to exclude it but not in surfraw when running duckduckgo. A little after Breakfast today I'll go onto duckduckgo directly and try a negative search the way it's done in google and see if it works. If it works, the surfraw duckduckgo elvi could do with some improvement.
