This paper provides references to its research and development. [Methods]Analysis methods such as typical case study and comparative study are adopted to analyze four foreign representative collaborative information search systems,which are Annotate!,Cerchiamo,CoSearch and SearchTogether,comparing in the frame structure,supporting technology,function and evaluation. [Results] Explicit collaborative search systems support synchronous retrieval,adjusting by user interface,mostly for C/S structure,using instant messaging and automatic division technologies,which are functional richer.While tacit collaborative search systems support asynchronous retrieval,adjusting by deep algorithm,mostly for multi-level structure,using data or agent technologies,which are functional simpler. [Limitations] Due to the experimental research stage,experience research method isn’t adopted in this paper. [Conclusions] The development of collaborative search systems has no fixed way. User’s functional requirements and corresponding supported technologies should be taken into consideration when designing.
