What is Apache Lucene ?

Apache Lucene is A Java search engine that provides indexing and searching technology for your app, along with spell-checking, statistics, and tokenization features .

Apache Lucene is suitable for any application that requires support for full-text searching, while also keeping server resource consumption down and producing fast & high-accuracy results.Lucene is widely considered as one of the best search engines around, being at the core of many other search tools, the most famous being Apache Solr.Lucene is written entirely in Java and since being released by the Apache Foundation, it has been ported to many other languages and various bindings and wrappers exist as third-party developed software.

This is changelog for Apache Lucene version 5.3.0 / 4.10.4 / 3.6.2 :

  • All file access now uses Java’s NIO.2 APIs which give Lucene stronger index safety in terms of better error handling and safer commits.
  • Every Lucene segment now stores a unique id per-segment and per-commit to aid in accurate replication of index files.
  • During merging, IndexWriter now always checks the incoming segments for corruption before merging. This can mean, on upgrading to 5.0.0, that merging may uncover long-standing latent corruption in an older 4.x index.
