What’s New in v3.0.1:
Incorporating Apache Lucene 3.0.1, this release is now faster and more flexible than before. Improvements include:

  • Removal of deprecated APIs
  • Upgrades to all accompanying components
  • Stability improvements for the indexing process
  • Increased scalability and accuracy for index segments
  • Important fixes to IndexWriter, Contrib’s Analyzers package and TokenStream API

Key features of the Certified Distribution include:

  • Complete version of Apache Lucene v3.0.1
  • 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.
