As search engines are playing a more and more important role in information activites, the related evaluation methods are an urgent issue. According to the features of search engines, based on a wide review of related literature both at home and abroad, the paper proposes to use the qualitative and quantitative analysis method for filtering the established indexes, and 13 evaluation criteria are established in 3 categories which are the index database, the retrieval effects, and the user friendliness. The weights of these evaluation criteria are calculated by Analytic Hierarchy Process based on the index value of TOPSIS. A complete evalution system is built and then several Chinese search engines are selected as the objects to use the Technique for Order Preference by Similarity to obtain an Ideal Solution for the final evaluation results. The paper discusses what should be done to improve the search engines in the future.
