More quick results and embeds

[ghost]

Is your feature request related to a problem? Please describe.

Yeah, it's about some features that a lot of other search engines provide that is missing in here.

Describe the solution you'd like

Adding more quick results and embeds, for example

Asking DDG a question results in :

But Searx doesn't seem to have a thing for this, as it results in a regular search.

Another example :

DDG neatly puts an embed next to the site (even though it's unrelated to the question but forget about that), showing a possible answer, while Searx seems to only show results from Stackoverflow

Yet another example :

Here, we ask DDG a basic math problem, and it neatly shows the result to us, with a calculator screen allowing us to do future calculations. This feature does not exist in Searx.

Describe alternatives you've considered

While clicking on the first result is one of the things that come to mind, it'd still be cool to have basic possible answers such as these to be embedded on our search results. It seems to partly work for stuff like when i search for "Apple" i can see the company on the side, but it can be greatly expanded.

Additional context

It may be a little out of scope for this project, but i really want to see Searx noıt be inferior to the engines it uses, so this is the reason why i'm creating this feature request.
