The Search theme setting controls the theme's search function, mainly found in the header and home page section.
Control what can be searched
Enable Show blog posts and pages in search results to expand the search criteria to include your store's blog posts and static pages.
Adjust the search results page layout
Reach's search results page will resemble the collection page layout, using a scattered and offset display. Select Enable standard product grid to use a uniform grid for the search results page instead.
Adjust the products per row
Use the Products per row slider to control how many products are included in horizontal rows.
Adjust the products per page
Use the Products per page slider to control the number of products gathered and presented on the first search results page. Using a lower value will not decrease the number of search results, but rather how many are included on the initial page. More items can be viewed by selecting the pagination links at the bottom of the page.
