Universal Search can be used as a form of site search for consumers to learn anything about a brand. When used effectively, it should be the entry point into search on a website. It searches across different vertical search experiences through a federated architecture to deliver users the best results.
Generally, Universal Search doesn't include any filters or facets and just has a single search bar.
