Based on research papers indexed by Web of Science, EI and CNKI on mobile search, this paper firstly extracts the high-frequency keywords and authors, then analyzes the research focus, sub-fields and the outstanding research teams in China and abroad using the methods of statistical analysis, bibliometrics, social network analysis etc. The further knowledge mapping results shows that studies of mobile search in China and abroad start almost simultaneously. Studies abroad are deeper, contain more sub-fields and more productive research groups, while studies in China still mainly focus on the conceptual introduction, and few research teams is stable and outstanding.
