Search engine duckduckgo URL results 404

[Tomas Nordin <tomasn@xxxxxxxxxx>]

Hello w3m Hackers

This is likely not a bug in w3m but I try with this list anyway since it
happens with w3m.

I have this entry in w3m-search-engine-alist:

'("duck" "https://duckduckgo.com/lite/?q=%s")

and that has been working fine for years. But now the resulting url:s
look like this, (with a search for "searching url duckduckgo")

https://lite.duckduckgo.com/l/?kh=-1&uddg=https%3A%2F%2Fduckduckgo.com%2Fparams

for example, and that link is broken. I cannot figure out how I should
compose the ACTION part of my search url string. Any ideas?

Best regards
