OneRetrieval: Unifying Multi-Branch E-commerce Retrieval with an Editable Generative Model

Xuxin Zhang, Ben Chen, Yue Lv +13

Industrial e-commerce search serves hundreds of millions of items through a multi-branch retrieval stage fused by hand-tuned merging without joint optimization. Generative retrieva…

Search-E1: Self-Distillation Drives Self-Evolution in Search-Augmented Reasoning

Zihan Liang, Yufei Ma, Ben Chen +4

Post-training has become the dominant recipe for turning a language model into a competent search-augmented reasoning agent. A line of recent work pushes its performance further by…

SD-Search: On-Policy Hindsight Self-Distillation for Search-Augmented Reasoning

Yufei Ma, Zihan Liang, Ben Chen +6

Search-augmented reasoning agents interleave internal reasoning with calls to an external retriever, and their performance relies on the quality of each issued query. However, unde…
