I reviewed the search engine you wish to add in WordPress. Unfortunately, there is not a similar Plugin for this.

You have done it correct by approaching their team.

In case you wish to add this in WordPress, it can be done via the Custom Code and embedding the quickanswer search in a WordPress page.

Thanks.

I site suckered it to look at the js files but it looks like its a specialist google search he’s created and has his google id etc in it linked to that .io website/

Is there any other way to embed in a site other than iframe. as I all I want is the search and answer form. I know how to iframe a given section of a page, but its all a bit ugly
