From federated to aggregated search
Fernando Díaz, Mounia Lalmas, Milad Shokouhi · 2010
Federated search refers to the brokered retrieval of content from a set of auxiliary retrieval systems instead of from a single, centralized retrieval system. Federated search tasks occur in, for example, digital libraries (where documents from several retrieval systems must be seamlessly merged) or peer-to-peer information retrieval (where documents distributed across a network of local indexes must be retrieved).
