The Design And Realization Of Full Text Retrieval Based On Lucene Mobile Phone

For professional Web sites, an excellent site inside the full-text retrieval system is indispensable. Typically there are two solutions: one is the use of common desktop search engine provides search functionality to retrieve the site station internal data; second is the development of a specific station dedicated full-text retrieval system. The main content is the subject of search engine technology, data crawling, segmentation, data analysis retrieval algorithm, design and implementation of a special search function to provide mobile vertical search engines. Vertical search engines, also known as the theme or topic search engine search engine. Such search engines collect a subject, a theme, an industry-wide information resources, and with a more detailed and professional approach to indexing and information resources described. Topic search engines to focus on their core technology to ensure complete collection and real-time updates on specific areas of information in providing professional information has a large general-purpose search engines can not match advantage. So topic significance is based on a comprehensive analysis by the Internet search technology, compared to various domestic and international search engine technology, and gives a search engine system based on mobile themes actual development, hoping to make some useful discussion.Technical papers on key topics for the search engine analyzes, we propose a subject-oriented search engine based on Lucene solutions and information to achieve the realization of a search for the phone. Topics on the subject of search engine key technologies namely: information capture, indexing, retrieval conducted in-depth analysis and research; research Heritrix applications and search strategies; focuses on Java toolkit index Lucene. Then, based on these key technologies offered to phone the theme of search engine design, including system design, technology strategy, structural framework, development environment, and design practice.Papers detailing the specific implementation process based on Lucene search engine mobile themes, testing and operation of the system on display. The main research topics include: research and analysis of key technologies and topics of general search engine search engine and compare different search techniques; on Apache Lucene full-text indexing engine kits in-depth analysis, Lucene search and compare similarities and differences between traditional database retrieval, and Chinese word segmentation; research topic in the search engine on the basis of the analysis of key technologies to achieve within the Lucene full-text retrieval system based on Web Site; analysis of the key technologies for the design and implementation, and analysis of results of search technology could be expanded and rebuilt.
