Design And Implementation Of Meta-based House Information Search System

Along with the quick development of the Internet, it is very difficult to find the needed information on the Internet. The search engine solved the issue.The work of this paper focused the related technology for house information search based on Meta Search Engine. The main works were as follows:1. The paper preseneted the related technology of the search engine and meta search engine, such as coming, development and the structure. The full-text search engine is introduced as its information and development, system architecture and so on. The collecting, indexing, retrieval and related technical of search engines are in-depth studied. The packages of Lucene in Apache full-text search system are analysed. The system tructure, the system features, the data stream and the structure of index file in Lucene system are deeply struied. The important packages in Lucene are analyzed. The technology system and evaluation indicators of Meta Search are focused on. At the same time, the key technologies such as house information models, selection method of members search engine was introduced.2. The house information vector model is proposed. The model builted, structure, organization have been focused on and the demand for search conversion algorithm is gived out.3. The the members selection strategy is proposed. The character evaluation method of the member engine is given. According to house information model, the member engine relation is calculated. The reasonable member engine are selected。4. By researching the main technoloties of house information search engine, a house information search engine was disigned and built. The needs of the system are analyed and system framework and structure are proposed. The various subsystems, such as information search subsystem, the index subsystem are detailed designed and implemented, and gives part of the implementation code. The house information search system based on Lucene has good scalability. It fits the house information search system used widely at present.
