Merge on full flush is enabled now by default with a timeout of 500ms, giving the merge policy a chance to merge NRT segments together before publishing a new point-in-time view of the IndexReader.The release is available for immediate download at: This release contains numerous bug fixes, optimizations, and improvements, some of which are highlighted below. It is a technology suitable for nearly any application that requires structured search, full-text search, faceting, nearest-neighbor search across high-dimensionality vectors, spell correction or query suggestions. ![]() The Lucene PMC is pleased to announce the release of Apache Lucene 9.3.0.Īpache Lucene is a high-performance, full-featured search engine library written entirely in Java. 29 July 2022 - Apache Lucene™ 9.3.0 available ![]()
