【Lucene之Luke 介绍】

Lucene is an Open Source, mature and high-performance Java search engine. It is highly flexible, and scalable from hundreds to millions of documents.

Luke is a handy development and diagnostic tool, which accesses already existing Lucene indexes and allows you to display and modify their content in several ways:

• browse by document number, or by term
• view documents / copy to clipboard
• retrieve a ranked list of most frequent terms
• execute a search, and browse the results
• analyze search results
• selectively delete documents from the index
• reconstruct the original document fields, edit them and re-insert to the index
• optimize indexes
• and much more...

 

luke是一个用于Lucene/Solr/Elasticsearch 搜索引擎的，方便开发和诊断的 GUI（可视化）工具。它有以下功能：

• 查看文档并分析其内容（用于存储字段）
• 在索引中搜索
• 执行索引维护：索引运行状况检查；索引优化（运行前需要备份）
• 从hdfs读取索引
• 将索引或其部分导出为XML格式
• 测试定制的Lucene分析工具
• 创建自己的插件
