The sensitivity and accuracy of the retrieval results directly affect the results in the systematic review of biomedical researchers. However, different retrieval methods and retrieval tools lead to different retrieval results. In this paper, we first evaluate the effects of Boolean logic retrieval, hierarchical retrieval, topic retrieval and full-text retrieval on the retrieval results of systematic reviews. We then introduce the application of one-stop search tool (Google Scholar and resource discovery system) in systematic review, and compare the effects of different one-stop search tools.
