Sitecore Search lets you create search and recommendation experiences for your content across all your channels. Using Search JS SDK and UI Components packages is the fastest way to integrate Search experiences into your Preact applications. The two packages are exclusively created for Preact. You can install them in your project to access their contents. At compile time, the JS SDK is integrated into your Preact browser application.
The Search JS SDK package contains components, functions, and query hooks.
For rapid integration, you can install the Sitecore Search UI components package which contains headless primitives and widget templates for your Preact application.
