The currently abundant bibliography on healthcare can make the search process an exhausting and frustrating experience. For this reason, it is essential to learn the basic concepts of research question formulation, information sources, and search strategies to make this process more efficient and user-friendly. The search strategy is an iterative process that allows the incorporation of tools and terms in the strategy design to optimize evidence retrieval. Each strategy varies according to the questions, the language used, the source of information accessed, and the available tools. This article is part of a methodological series of narrative reviews on biostatistics and clinical epidemiology. This narrative review describes the essential elements for developing a literature search strategy and identifying the relevant evidence concerning a clinical question through familiar and accessible sources (such as Google and Google Scholar), as well as search interfaces and technical-scientific databases focused on biomedical knowledge (PubMed and The Cochrane Library).
目前关于医疗保健的文献资料非常丰富，这使得搜索过程变得既疲惫又令人沮丧。出于这个原因，学习研究问题制定、信息来源和搜索策略的基本概念对于使这个过程更加高效和用户友好是至关重要的。搜索策略是一个迭代的过程，它允许在策略设计中纳入工具和术语，以优化证据检索。每个策略都根据问题、使用的语言、访问的信息来源和可用的工具而有所不同。本文是关于生物统计学和临床流行病学的叙述性综述方法系列的一部分。这篇叙述性综述描述了制定文献搜索策略的基本要素，并通过熟悉和易于访问的来源（如 Google 和 Google Scholar）以及专门针对生物医学知识的搜索界面和技术科学数据库（PubMed 和 The Cochrane Library）确定与临床问题相关的证据。
