摘要
当前的信息检索智能体在长周期探索中难以保持专注度与连贯性,因为将搜索状态(包括规划流程和海量搜索结果)记录于单一纯文本语境存在固有脆弱性。为此,我们提出表格式搜索框架,该结构化规划框架将信息检索任务重新定义为表格填充任务。该框架将每个查询映射至外部数据库维护的结构化表格模板中:行代表搜索候选项,列表示约束条件或所需信息。这种表格能精准管理搜索状态:已填充单元格严格记录历史搜索记录与结果,而未填充单元格则构成显式搜索计划。关键的是,该框架统一了三种不同的信息检索任务:深度搜索、广度搜索以及具有挑战性的深度广度联合搜索。大量实验表明,在包含多智能体框架和商业系统的三类基准测试中,该框架显著优于众多先进基线方法。此外,我们的分析验证了该框架在长周期信息检索中具有卓越的鲁棒性,同时兼具高效性、可扩展性和灵活性。代码与数据集已开源:https://github.com/AIDC-AI/Marco-Search-Agent。

Current Information Seeking (InfoSeeking) agents struggle to maintain focus and coherence during long-horizon exploration, as tracking search states, including planning procedure and massive search results, within one plain-text context is inherently fragile. To address this, we introduce Table-as-Search (TaS), a structured planning framework that reformulates the InfoSeeking task as a Table Completion task. TaS maps each query into a structured table schema maintained in an external database, where rows represent search candidates and columns denote constraints or required information. This table precisely manages the search states: filled cells strictly record the history and search results, while empty cells serve as an explicit search plan. Crucially, TaS unifies three distinct InfoSeeking tasks: Deep Search, Wide Search, and the challenging DeepWide Search. Extensive experiments demonstrate that TaS significantly outperforms numerous state-of-the-art baselines across three kinds of benchmarks, including multi-agent framework and commercial systems. Furthermore, our analysis validates the TaS's superior robustness in long-horizon InfoSeeking, alongside its efficiency, scalability and flexibility.
