Abstract: A method, apparatus and system for realizing multi-person conversation are disclosed. The method includes: a multi-person conversation window includes a searching window, and a client end receives a searching command and searching information through the conversation window in a multi-person conversation process. The searching information is passed to a server by the client end when the client end receives the searching command. The searching result information matched by the server based on the searching information and sent by the server is received by the client end. The received searching result information is displayed on the searching window of the conversation window by the client end. The method enables the combination between multi-person conversation and webpage searching, so that the switching between a searching webpage and a conversation window can be avoided, and the conversation among multiple persons can be facilitated.
