Lucene is a subproject of the Jakarta Project Team of the Apache Software Foundation. It is an openSource codeIs not a complete full-text search engine, but a full-text search engine architecture, provides a complete query engine and index engine, some text analysis engines (two Western languages: English and German ). Lucene aims to provide software developers with a simple and easy-to-use toolkit to conveniently implement full-text retrieval in the target system, or build a complete full-text retrieval engine based on this.

 

Lucene is a full-text search based on Java, not a complete search application, butCodeLibrary and API, which can easily provide the search function for applications. In fact, Lucene's function is to index several strings provided by developers, and then provide a full-text search service. Users can provide search keywords to the search service, the search service tells the user about the strings that appear in the keywords.

For details about Lucene, refer to the official website: http://developere.apache.org /.

Previously, a Lucene website in China gave a detailed introduction to Lucene's principles, structures, and APIs. http://www.e.com.cn/.but it is no longer effective.

For some entry-level examples of Lucene, refer to the example code provided by the blogger: "create search and learning instance source code of Lucene", "query regenxquery by Lucene regular expressions", and "Lucene filter query instance ".".

Here, we will not elaborate on Lucene too much. Add an article about Lucene compiled from the Internet :《 Open-source full-text retrieval engine Lucene.
