Requeries
Requeries are follow-up queries issued during information retrieval tasks with the goal of refining, expanding, or redirecting the original search. The concept is common in interactive search environments, where users iteratively adjust terms, constraints, or topics after inspecting initial results. It also applies to automated systems that generate revised queries in response to user signals such as clicks, dwell time, or explicit relevance judgments, in order to improve subsequent results.
In practice, requeries occur in search engines, database query interfaces, and data exploration tools. They enable
Mechanisms for generating requeries include relevance feedback, query expansion, session-based minimization or diversification, and learning-to-rank loops.
Benefits of requeries include higher precision, improved recall for targeted intents, and better user satisfaction in
