The Smart Search add-on provides search suggestions as you enter into the search field, making things quicker for customers.
In previous versions of the Debutify theme, customers can only search for products.
In Debutify 4.7.0 and later themes, the search functionality expands to include Collections, Products, Blog Articles, and Pages.

Select your Debutify Shopify theme (4.7 or later versions) and click on Customize.
Click on Theme Settings.
Click on Advanced Settings.
Enable search and select what the search criteria should include.
Click Save to apply the changes.
