LucidWorks Certified Distribution for Lucene

LucidWorks Certified Distribution for Lucene is a comprehensive, tested version of the Apache Lucene library, based on the most recent stable Lucene version with additional bug fixes, productivity and index tools. For those wishing to use the Java Lucene library directly, LucidWorks Certified Distribution for Lucene v2.9 provides a supported, free and complete version of Apache Lucene which includes additional bug fixes and software components that have been tested by Lucid’ Imagination, as well as 30 days of free Get Started assistance. (For most developers building search applications with Lucene/Solr technology for a web site, product or internal organizational use, Apache Solr is the logical starting point; check out LucidWorks Certified Distribution for Solr.)

LucidWorks Certified Distribution for Lucene v2.9 is based on the most recent stable release of Apache Lucene (v2.9.1) and includes bug fixes and performance enhancements pulled from the current trunk of the Apache Lucene project. Key features include:

• Complete version of Apache Lucene v2.9.1
• Additional bug fixes from the current trunk of the Lucene project
• 30-day free Get Started assistance
• LucidKStemmer: Lucid's optimized version of KStemmer, the Krovetz stemmer available from the University of Massachusetts. A stemmer reduces words to a root form, providing the ability to search for derivatives of a stem word (e.g., "team" is the stem of "teams"). This is a dictionary based inflectional stemmer that stems less aggressively than the standard Porter stemmer included with Apache Lucene. LucidKStemmer is English-only at this time.
• Lucene Index Toolbox (Luke): LucidWorks Certified Distribution for Lucene also includes Luke, a handy development and diagnostic tool that no Lucene/Solr developer should be without. Luke allows developers to examine and modify existing Lucene indexes, and quickly identify issues in data feed, search accuracy and search relevancy.
