The availability of information in different languages on the Internet allows multilingual web users to search in multiple languages for the same search task. When searchers can search in multiple languages, they may combine these languages in various ways during searching. Few studies have examined multilingual web users' language switching behaviors in two or more languages online, specifically their code‐switching search patterns. This research investigates native Chinese web users' code‐switching (Chinese‐English) search patterns in their information seeking process through controlled lab experiments and interviews. Results reveal three general code‐switching search models for multilingual web users for their search tasks. Findings highlight factors and reasons for multilingual web users' situational and metaphorical code‐switching during their information search on the Web. We find that multilingual web users switch code situationally due to pragmatic reasons such as information sufficiency, language proficiency, information verification, context, and translation. Metaphorical code‐switching behaviors were motivated by the searchers' language image, cultural perspective, website credibility, sense of belonging, and psychological acceptance. We also investigate these users' code‐switching search strategies. The study aims to provide design implications for website design concerning multilingual web users' code‐switching search strategies, habits, and needs.
