摘要：
The four most popular search engines PubMed/MEDLINE, ScienceDirect, Scopus and Google Scholar are investigated to assess which search engine is most effective for literature research in laser medicine. Their search features are described and the results of a performance test are compared according to the criteria (1) recall, (2) precision, and (3) importance. As expected, the search features provided by PubMed/MEDLINE with a comprehensive investigation of medical documents are found to be exceptional compared to the other search engines. However the most effective search engine for an overview of a topic is Scopus, followed by ScienceDirect and Google Scholar. With regard to the criterion " importance" Scopus and Google Scholar are clearly more successful than their competitors. © 2011.
