The network information resources are exploding. When college students get the information resources they need, they are more and more dependent on the network search engine. However, due to the uneven quality of search engines, college students' information literacy and retrieval ability need to be improved, and it is difficult to retrieve the information they need comprehensively and accurately. Therefore, it is very important to study the behavioral characteristics and influencing factors of contemporary college students when searching for the required information resources through the search engine on the Internet, put forward targeted suggestions and strategies, and set appropriate search teaching tasks and contents.
