Out of the box SXA
Search Results component shows only page
How can I customize that component to show page
You should use Rendering variants for this.
When you edit the search results rendering properties, there is a field which allows you to select rendering variant. You can choose from the couple of default ones but you can define your own.
In order to define a variant you have to:
Variant definitionin the
Presentation\Rendering Variants\Search results
