Two types of brain activity measurement experiments were executed. Generation of search query is an important process because without this step the information search process cannot start, and the selection of query keywords directly influences the quality of the search result. The two types differ in the text amount that is displayed to the subject and the generation method of search keyword. Analysis of fMRI experimental data indicates the presence of a common brain network and brain networks specific to each search task.

进行了两种类型的脑活动测量实验。搜索查询的生成是一个重要的过程，因为没有这一步信息搜索过程就无法开始，而查询关键字的选择直接影响到搜索结果的质量。这两种类型的不同之处在于显示给主题的文本量和搜索关键字的生成方法。功能磁共振成像实验数据的分析表明，存在一个共同的大脑网络和特定于每个搜索任务的大脑网络。
