软件工程毕业论文外文文献—Apache Lucene 官网
外文原文Apache Lucene WebsiteLucene is a Java full-text search engine. Lucene is not a complete application, but rather a code library and API that can easily be used to add search capabilities to applications.This is the official documentation forApache Lucene 4.7.1. Additional documentation is available in theWiki.Getting StartedThe following section is intended as a "getting started" guide. It has three audiences: first-time users looking to install Apache Lucene in their application; developers looking to modify or base the applications they develop on Lucene; and developers looking to become involved in and contribute to the development of Lucene. The goal is to help you "get started". It does not go into great depth on some of the conceptual or inner details of Lucene:Lucene demo, its usage, and sources: Tutorial and walk-through of the command-line Lucene demo.Introduction to Lucenes APIs: High-level summary of the different Lucene packages.Analysis overview: Introduction to Lucenes analysis API.
