# R-Search: Empowering LLM Reasoning with Search via Multi-Reward Reinforcement Learning

[Paper](https://huggingface.co/papers/2506.04185)

**R-Search** is a novel reinforcement learning framework for reasoning–search integration. It enables LLMs to autonomously perform multi-step reasoning with deep search interaction, and to learn optimal reasoning–search trajectories via multi-reward signals, substantially improving performance on complex logic- and knowledge-intensive tasks.

## Trained Models

We open-sourced the following models trained only on the 2wikimultihopqa training set:
