Live Search is a set of standalone packages for Adobe Commerce that replaces the standard search capabilities. The Live Search module is installed from the command line of the server and connects to your Commerce installation as a service. When the process is complete, Live Search appears on the Marketing menu under SEO & Search in the Commerce Admin.
The Adobe Commerce side of the architecture includes hosting the search Admin, synchronizing catalog data, and running the query service. After Live Search is installed and configured, Adobe Commerce begins sharing search and catalog data with SaaS services. At this point, Admin users can set up, customize, and manage search facets, synonyms, and merchandising rules.
