Upon requirements analysis and high-level design, this paper finally establishes the architecture and main solution to build a distributed shopping search system. This paper illustrates the realization of the background system of a 3G-oriented comparison shopping search engine, especially the index and query subsystem. This paper first introduces a way to build a distributed search cluster, focusing on the solutions of web load balancing, distributed parallel search, remote method invocation, analysis of user queries and user search behavior log. Then the implementation of distributed search cluster nodes is described in this paper. With an integrated high efficient Chinese word segment system written in C language, a custom Chinese analyzer is constructed based on Lucene. This paper realizes full-text index, as well as total index, incremental index and dropping index. It implements full-text retrieval, including parsing the queries, filtering and sorting the search results. On the foundation of the Lucene original document relevance sort algorithm, this paper proposes an improved sorting algorithm for the secondary search based on commercial properties, which contributes to a way of sorting by price performance ra
