BTW I also like this idea.
So +1 quack!

On the help site about this it states "If you use our sort by date feature (for recent pages) there is a date displayed next to each domain.".
However this is not the case. In my case it displayed the results as it normally would only sorted differently.

There is already something similar available. At least for CC licenses. They have tree layers which includes a technically layer.
This way search engines can index it.

BTW I really like the idea of photo filtering. This is a feature DuckDuckGo really lacks.
E.g. filtering only CC-licensed images like on the CC site: http://search.creativecommons.org/

Of course it would be great if this would be extended to any search, but I think photos are the most important thing.

My text was originally this one:

But this is a single line field, so how can I add more than one paragraph there?
Now it's all in one line... :(

Are there any news about this topic?
Personally I would also support this idea.

+100
Yeah... DANE (with DNSSEC)

More information: https://en.wikipedia.org/wiki/DNS-based_...
Here is a list of sites which already supports DANE: http://www.internetsociety.org/deploy360...

This way you can make the SSL connection much more secure and be more independent from certification authorities.
