Federated Architecture (or "Federated Search") is a technology framework wherein the search engine queries multiple data sources and aggregates the results in one unified experience for the user.
In Yext Search
Yext Search uses a federated architecture to search across verticals within your Knowledge Graph, all from one search query. Whether the user search is for products, professionals, or locations, this architecture will identify the context and return results across the verticals. Search can also integrate with third-party systems (e.g., Zendesk) to return even more results to users — all in one place.
