Hi Aaron,
The Examples page on our demo is simply an archive page for the examples, it’s layout is custom coded – we are using a custom made underscores theme on that page. Unfortunately for that exact layout we can’t make a tutorial, as it’s outputted by the theme and independent from the search plugin.
In the search plugin you can turn on searching for the archive pages via these settings. Similarly, you can use that feature with any theme for the archive pages. Most themes allow you to edit the archive pages layout, so there is a good chance you can create a very similar layout to our examples page.
