当一个人发出查询时，这个人对将返回的搜索结果有期望。这些期望可以基于当前的信息需求，但也会受到搜索者认为搜索引擎的工作方式，相关结果的排名以及个人对该主题的任何先前搜索的影响。本文深入探讨了人们在初始查询过程中对搜索结果列表的期望如何影响他们对未来重复搜索结果列表的感知和交互。三项研究提出了深入了解人们如何回忆，识别和重用的结果。第一项研究（关于回忆的研究）探讨了人们对以前浏览过的搜索结果列表的回忆。第二项研究（关于识别的研究）建立在第一项研究的基础上，揭示了人们通常会将结果列表识别为他们以前见过的结果列表，即使它完全不同。只要这些方面的记忆是关于最初的名单保持不变，其他方面可以改变显着。这是有利的，因为正如第三项研究（重用研究）所示，当结果列表似乎已经改变时，人们很难重用列表中以前查看过的内容。他们不太可能找到他们想要的东西，对结果的质量不太满意，更有可能发现任务很难，更有可能花很长时间搜索。尽管表面上的一致性对于重用很重要，但是人们无法识别变化使得没有停滞的一致性成为可能。新的相关结果可以在旧的结果被遗忘的地方呈现，使得新旧内容都很容易找到。
When a person issues a query, that person has expectations about the search results that will be returned. These expectations can be based on the current information need, but are also influenced by how the searcher believes the search engine works, where relevant results are expected to be ranked, and any previous searches the individual has run on the topic. This paper looks in depth at how the expectations people develop about search result lists during an initial query affect their perceptions of and interactions with future repeat search result lists. Three studies are presented that give insight into how people recall, recognize, and reuse results. The first study (a study of recall) explores what people recall about previously viewed search result lists. The second study (a study of recognition) builds on the first to reveal that people often recognize a result list as one they have seen before even when it is quite different. As long as those aspects that the searcher remembers about the initial list remain the same, other aspects can change significantly. This is advantageous because, as the third study (a study of reuse) shows, when a result list appears to have changed, people have trouble re-using the previously viewed content in the list. They are less likely to find what they are looking for, less happy with the result quality, more likely to find the task hard, and more likely to take a long time searching. Although apparent consistency is important for reuse, people's inability to recognize change makes consistency without stagnation possible. New relevant results can be presented where old results have been forgotten, making both old and new content easy to find.
