Researchers have introduced a new framework for evaluating LLM-guided search systems, which iteratively generate queries and retrieve documents. This framework models the search environment as ranked lists and defines two core actions: 'select' to advance through a ranking and 'spawn' to generate a new ranking via query reformulation. The approach allows for various retrieval strategies to be expressed as policies within a common environment, with a natural reinforcement learning interpretation. Experiments demonstrate that both the retrieval method and the 'deep research' policy significantly impact performance, particularly in high-recall information retrieval scenarios. AI
