The Design And Implementation Of Full-text Retrieval System

The construction and evolution of modern Internet and campus network promotethe application development based on Internet and campus network. The digitalizationresearch of collegial management gains its recognition. The graduate dissertationFull-text retrieval system is the important part of the college daily management. Withthe colleges’ scale extending, the amount of dissertation increases greatly, so the setupof the dissertation Full-text retrieval system becomes necessary more and more.Full-text retrieval is unstructured tools, which is an important part of informationretrieval technology. by some grrogramme,The full-text retrieval will build an index toshow the frequency and position of the word that appeared in the whole book.And thespecified information, such as the number, location, and other statistics analysis areincluded. When the user indexs, lexical information is returned to the user by hecomputer immediately.In this thesis, through analyzing the current mainstream retrieval technology anddevelopment status, it mainly introcuced full-text search technology lucene principlesand technical characteristics.At the same time,it analysised the functional architectureof the open-source full-text search lucene algorithm.At the same time, the paper designed a full paper retrieval system based onlucene full-text search architecture,The system can submit papers, having a function offuzzy query precise query duplication.Compared with traditional indexing techniques, itis faster, better and conducive to the collection and maintenance of thesis. Iteventually reached the application standard of full-text retrieval system.
