FAQ Magento Integrate Algolia to your search page template

The realtime search experience implemented by the extension is done using JavaScript in your end-users browsers and therefore cannot have access to the templates of your original theme (which is rendered with PHP from your backend). Instead, it creates a search page with a default theme that you may need to adapt to fit your UI needs.

But you can still customize the design of the instant search results page & the auto-complete menu. See Customization section in documentation.
