Lucene is one of the Jakarta projects of Apache Software Foundation which is an open source full text search engine toolkit, itвЂ™s not a full text search engine, but a full-text search engine framework that can provide users complete query engine, text indexing engine and part of the analysis engine, it can also provide a simple but powerful API interface so that people can conveniently and quickly develop the search engine.ДЈ.1.

Search requests are submitted by the users and information retrieval systems to preprocess and search the information eventually return user the information.ДЄfter the information retrieval system search the information that the users need and it will filter or sort the information by making a certain rule and then return the user related information. Large-scale information retrieval systems such as Google, Baidu take advantage of the approach of inverted index.ДЄfter indexing the documents, you can start to search information you need. Which way do you use depends on the scale of information retrieval system. Indexing can greatly improve the speed of information retrieval. Once the model is confirmed, we should not make further more changes any longer.Д¬reate index with the model according to the text of database. The model has an identifiable and low degree of redundancy. In recent years, Lucene has become one of the most highly praise and most popular information retrieval library.ДЇirstly, we should build a text database which is used to store all information retrieved by the user, then determine text model of retrieval system. Lucene is a pure Java software project which is mature, free and open source. Create all the possible terms in the index which are searched by network users as well as help people to manage and order extensive information and enable network users to quickly and easily retrieve any information they need. Full-text search technology provided us with the information retrieval tool according to the content of data rather than the external features based on a variety of computer data such text, sound, image as processing object. The core of information search is the full-text retrieval technology.
