Added filtering capabilities

[eliseomartelli]

I love your search card so I thought that I may help by adding some domain-filtering capabilities :)

Great addition, thanks! Was thinking about adding the same thing as well 😊 Added a small comment you can have a look at. Would also like it that you update the readme and extend the example, so people know how to use it.

I think we can close this 'cause the regex filter already covers this usecase :)

[postlund]

I still see a valid purpose with this change, as it allows permanent exclusion of results that you might never wanna see.

Mind resolving the conflicts @eliseomartelli?

Can we get some examples of the regex if this isn't going to be merged in?
