QueryRoute is introduced, a benchmark that freezes the expensive artifacts needed to study this inference-time decision problem reproducibly: original queries, generated variants, ranked lists under multiple retrievers, retrieval scores, and per-query oracle labels.
ExecRubrics achieves up to 320 times faster evaluation while matching or exceeding the accuracy of traditional black-box judges in long-form response assessments.
Simple Boolean queries can outperform complex retrieval methods, achieving competitive search performance without the need for supervised learning.
LLM-powered query reformulation, a hot topic in IR, often fails to translate gains from lexical to neural retrieval, and bigger models don't always help.
Stop prompting LLMs to blindly rewrite queries – ReFormeR distills query transformations into reusable patterns that actually improve retrieval.
