Research and design of the search engine based on peer network

With the development of Internet, as Internet users needed information search tool, the search engine gets more and more users recognition. In order to maximize the sharing of resources, combined with peer network applications, we use P2P technology and lightweight SQLite3 database to research and design an embedded search engine system which is compatible with PC and mobile phone, while mobile phone as Peer of the network has a search function that is independent, it does not need to connect PC or other devices and can directly implement the search function [1]. This paper also describes the strategy in detail on implementation processes, key points, relationships of each parts.
