The invention provides internet search system and method based on a point-to-point network, wherein a search terminal is arranged at each search node to form a point-to-point network among nodes; the search request is progressively sent to other search nodes by utilizing a release and fax mechanism of the information in the point-to-point network; each search node respectively responses the search request and searches based on locally-stored index banks of each search node; and the search results of each search node are finally converged on original search nodes, and aggregated and sorted by utilizing the original search nodes. The invention completely changes the architecture of the traditional search systems, provides a new search system architecture and thoroughly solves the working pressure problem of a search engine server in the prior art.
