The search results page displays the store contents that match the keywords provided in the search feature.
Theme editor settings for search results
You can customize the page by searching for something in the theme editor's preview, then opening up the Search results page section that appears in the left-side settings.
Use the Products per page slider to control how many products are gathered for the search results page. Include between 6-30 products on your search results page.
Use the Product aspect ratio dropdown to select a display option for the product images. The aspect ratio is the relationship between the width and height of the image, so this setting controls how the images fit into the page's containers.
