luke

Luke, the Lucene Toolbox Project + JavaFX

Luke atop JavaFX.

Luke is the GUI tool for introspecting your Lucene / Solr / Elasticsearch index. It allows:

  • Viewing your documents and analyzing their field contents (for stored fields)
  • Searching in the index
  • Performing index maintenance: index health checking, index optimization (take a backup before running this!)
  • Testing your custom Lucene analyzers

Search engines luke can deal with

In no particular order:

  • Apache Lucene. Most certainly luke can open lucene index produced by pure Lucene. Do people make pure Lucene indices these days?
  • Apache Solr. Solr and Lucene share the same code base, so it is natural that luke can open Lucene Index produced by Solr.
  • Elasticsearch. Elasticsearch uses Lucene as its lowest-level search engine base. So luke can open its index too!

Brief project history

  • The original author is Andrzej Bialecki
  • The project has been mavenized by Neil Ireson (see google group discussion here)
  • The project has been ported to Lucene trunk (marked as 5.0 at the time) by Dmitry Kan
  • The project has been back-ported to Lucene 4.3 by sonarname, who later decided not to continue supporting the project
  • There are updates to the (non-mavenized) project done by tarzanek
  • The UI (and some of core components) has been re-implemented on top of JavaFX by Tomoko Uchida.

This project's goal

  1. Keep the project mavenized (compatible with Apache Lucene and Solr style)
  2. To port the thinlet UI to an ASL compliant license framework so that it can be contributed back to Apache Lucene. Current work is done with JavaFX.
  3. Maintain a single point of trust for the development and updates of the tool. That said, everyone is welcome to join.

System Requirements

Java 8+ and JavaFX runtime are required.

Launching luke

From source code

  1. Clone the repository.
  2. Run mvn install from the project directory. (Make sure you have Java and Maven installed before doing this)
  3. Use luke.sh or luke.bat for launching luke from the command line based on the OS you are in.

Using a release

releases page contains stable releases of luke. Download the respective release, unpack and run a shell or batch scripts (or directly with java -jar if you prefer it that way).

Running luke with a custom analyzer or codec

See luke.sh for an example of launching luke with custom components.

Documentation

The documentation is being written along the way of discovering the luke's usage scenarios.

Releases

All of the releases you find under the "releases" link above are versioned after the Lucene's version they use.

Usually we don't do releases for minor version upgrades, because the major release usually can read the index of the next minor release.

An example: lucene 4.8.0 can read the index generated by lucene 4.8.1. Hence luke 4.8.0 can read too.

Conclusion: in order to find a luke release that can read an index of your version of Lucene, pick the closest major version and download luke for that from the releases page.

Where is (legacy) Thinlet version luke?

luke-thinlet branch holds Thinlet version. From version 7.3.1, the main branch is running JavaFX version luke and Thinlet version is not maintained/updated.

Where is luke 4.4.0 ?

There is no separate luke 4.4.0 release, but luke 4.5.0 should open the Lucene 4.4.0 index just fine.
