Research And Design Of Public Opinions Information Search System Base On LUCENE

When Internet and communication technology is rapidly developed, the internet nodes havebecome more and more. It has been a very difficult problem to find public opinions informationincreasingly. the Lucene-based public opinions information search system has been deep anddetailed studied.(1) The status, development, system architecture of search engine is introduced and thecollecting, indexing, retrieval and related technical of search engines are in-depth introduced.The structure, features, the data stream and the structure of file of Lucene are dipth analyzed.(2) The operation requirement, system requirement and feasibility analysis of the publicopinions information search engine have been detailed analysis and the subsystem function havebeen designed.(3) Based on the key technologies of public opinions information search engine, a publicopinions information Information search engine was impleted. The needs and framework of thesystem are proposed. The main subsystems such as collecting, indexing and retrieval are detaileddesigned.The Lucene-based public opinions Information search has good scalability and fits thepublic opinions Information searching used widely.
