摘要：The ability to search and retrieve information from the web efficiently and effectively is great challenge of search engine. Information retrieval on the Web is very different from retrieval in traditional indexed databases because it's hyper-linked character, the heterogeneity of document types and authoring styles. Thus, since Web retrieval is substantially different from information retrieval, new or revised evaluative measures are required to assess retrieval performance using search engines. In this paper we suggested a number of evaluative measures to evaluate the effectiveness of search engines. The motivation behind each of these measures is presented, along with their descriptions and definitions
