Researchers have introduced QueryRoute, a new benchmark designed to evaluate query reformulation selection strategies for LLM-based information retrieval. This benchmark addresses the challenge of choosing the optimal query reformulation for a given query, domain, retriever, and model by providing a standardized set of artifacts. QueryRoute includes 3,757 queries, 11 candidate systems, five reformulator backbones, and three retrievers across multiple datasets, resulting in over 600,000 retrieval outcomes. Initial benchmarking of various selection methods revealed significant potential for improvement over fixed reformulators, though current methods only capture a fraction of this potential, with selector performance varying across different retrieval systems.
