[Purpose/significance] This study aims to explore the differences between collaborative mode and individual mode of information search on search experience and search interaction, trying to understand the characteristics of collaborative information search from various angles.[Method/process] The experiment is designed based on books interactive retrieval platform (CLEF-Social Book Search). Sixteen independent and eighteen collaborative participants are recruited to the laboratory to complete different types of book search tasks. Users' interactions with the system during search are recorded through the backend server; while their search experience is recorded by questionnaires completed before and after the search. In data analysis, users' interactions and search experience are compared between two search modes.[Result/conclusion] (1) Search experience:Compared with individual searchers, collaborative searchers have better evaluation on experiment system function and higher evaluation on aesthetics, durability, novelty of the system, and participate in the search more intently. However, collaborative searcher felt a bit more frustrated and mentally taxing than individual searchers. (2) Search strategies:Compared with individual searchers, collaborative searchers make more decisions in the goal-oriented task, especially the decision of removing books from bookbag, which indicates collaborative searchers need to sort the books in the later stage. In the open-ended task, collaborative searchers spend more time before each decision than individual searchers, which is probably because of collaborative searcher's higher level of focus and participatory. This study helps understand about collaborative search through comparison with individual search, which may provide inspiration for collaborative search system design.
