Intro

Welcome to the luke wiki!

This page summarizes the features of the tool.

Luke is Lucene Indexing Toolbox created by Andrzej Bialecki. The tool solves the need of a Lucene / Solr engineer to have a deep view into what is actually stored in the index and get insight into the index stats.

The tool has evolved into a plugable framework. One of the notable plugins is the one allowing you to read a Lucene index stored in HDFS (Hadoop Distributed File System).

In the current 4.3.0 version (this project) the following plugins are available:

• Analyzer tool: Tool for analyzing analyzers, by Mark Harwood.
• Hadoop plugin: Open indexes located on any filesystem supported by Hadoop (0.20.1).
• Scripting Luke: JavaScript interactive shell powered by Rhino.
• Custom Similarity: plugin for designing custom similarity, powered by Rhino.
• Vocabulary Analysis Tool: Tool for showing index's vocabulary growth, by Mark Harwood.
• Zipf distributions: Tool for showing term popularity distributions, by Mark Harwood.
