信息搜索的模型，包括库尔索的信息搜索过程模型，描述了根本不同的宏观层面的阶段。当前的搜索系统通常不提供对这些阶段的支持，而是提供一组主要集中于支持微级搜索交互的静态特征。本文研究了搜索用户界面(SUI)功能在复杂任务的不同宏观阶段的效用。设计了一项用户研究，使用模拟的工作任务，明确地将用户置于复杂任务的不同阶段：聚焦前、聚焦后和聚焦后。对特征的主动使用、被动使用和感知的有用性进行了分析，以得出何时搜索特征最有用。我们的结果发现，在每个阶段之间，SUI功能的实用性存在显著差异。具体地说，我们观察到信息特征在每个阶段都是自然有用的，而输入和控制特征在聚焦前阶段之后的有用性下降，而个性化特征在聚焦前阶段之后变得更有用。从这些发现中，我们得出结论，如果在正确的时间提供，网络搜索界面中不太常见的功能可以为用户提供价值，而不会扰乱简单的搜索。
Models of information seeking, including Kuhlthau's Information Search Process model, describe fundamentally different macro-level stages. Current search systems usually do not provide support for these stages, but provide a static set of features predominantly focused on supporting micro-level search interactions. This paper investigates the utility of search user interface (SUI) features at different macro-level stages of complex tasks. A user study was designed, using simulated work tasks, to explicitly place users within different stages of a complex task: pre-focus, focus, and post-focus. Active use, passive use and perceived usefulness of features were analysed in order to derive when search features are most useful. Our results identify significant differences in the utility of SUI features between each stage. Specifically, we have observed that informational features are naturally useful in every stage, while input and control features decline in usefulness after the pre-focus stage, and personalisable features become more useful after the pre-focus stage. From these findings, we conclude that features less commonly found in web search interfaces can provide value for users, without cluttering simple searches, when provided at the right times.
