Understanding Federated Searching: A Comprehensive Overview

Federated searching simplifies the research process by allowing users to input a single search query into a federated search engine, which then translates it into the specific syntax required for multiple databases. The user interface remains consistent and familiar, presenting results from various resources such as e-journals and e-books in a single, combined list. This method enhances efficiency by aggregating results, removing duplicates, and providing full-text connections. Learn how federated searching plays a crucial role in effective information retrieval.
