基于丢弃的搜索是一种搜索复杂、未标记、非索引数据（例如数码照片、医学图像和实时监控数据）内容的新方法。这种方法的本质是基于查询特定内容的计算，并与人类认知进行管道化。在这种方法中，特定于查询的并行计算将搜索任务缩小到人类规模，从而使专家的专业知识、判断力和直觉能够影响搜索的特异性和选择性。在本文中，我们报告了 Diamond 项目中从将基于丢弃的搜索应用于健康科学的各种应用中吸取的经验教训。从用户的角度来看，基于丢弃的搜索具有独特的优势。从服务器硬件和软件的角度来看，它提供了独特的优化机会，与长期确立的存储设计原则相矛盾。这些独特的端到端属性共同预示着一种新的互联网应用类型。
Discard-based searchis a new approach to searching the content of complex, unlabeled, nonindexed data such as digital photographs, medical images, and real-time surveillance data. The essence of this approach is query-specific content-based computation, pipelined with human cognition. In this approach, query-specific parallel computation shrinks a search task down to human scale, thus allowing the expertise, judgment, and intuition of an expert to be brought to bear on the specificity and selectivity of the search. In this paper, we report on the lessons learned in the Diamond projectfrom applying discard-based search to a variety of applications in the health sciences. From the viewpoint of a user, discard-based search offers unique strengths. From the viewpoint of server hardware and software, it offers unique opportunities for optimization that contradict long-established tenets of storage design. Together, these distinctive end-to-end attributes herald a new genre of Internet applications.
