Design And Implementation Of Private Data Backup And Recovery Applications

With the continuous development of the Internet, more and more Internet applications come on, users can get more information through the Internet.As the number of users and user issues continue to increment, on the one hand the efficiency and accuracy of user search service can not be guaranteed, this greatly affects the user experience. On the other hand in the case of user questions and answers ever-expanding amount of data, the company has become increasingly difficult to manage data storage. So how effective user Q data management and search Internet applications has become an urgent problem, especially for such an application online question answering system, the efficiency and accuracy of search services greatly affects its survival.This article is in this background proposes solutions solr search service based on providing search services for online question and answer service.The main content of the work are as follows:First, the search engine technology for a detailed analysis and research. Analysis of the full-text search technology, processes and components for open source search engine for a detailed analysis and comparison, the final choice of the open source-based systems company-wide search engine solr. Then on Lucene and solr search engine for a detailed analysis of the search process, the indexing process and index storage structure has a very indepth understanding.Secondly, the Chinese word for a detailed analysis, the first of the Chinese word segmentation algorithm analysis and comparison, the current major Chinese word segmentation algorithm is: based on string matching segmentation algorithm, statistical segmentation algorithm and segmentation algorithm understanding based. Then the more popular Chinese word segmentation is performed by contrasting comparative analysis of selected after the heat source to compare Chinese segmenter Jcseg, and it had a certain optimization.The last of the Q & A search system for a detailed needs analysis, identifying needs,based on the system design, including the design of the system architecture and system flowcharts clean. On this basis, the system is divided into four modules: information collection module, document analysis module, indexing module and the search module.Then each of these four modules in detail the design and implementation.Based on online quiz solr search service greatly improves the user questions information storage and management efficiency by way of indexing documents organized and improve the efficiency and accuracy of search systems and external search services. Through this system,great to meet the company's needs in the search service.
