24 September 2018, Apache Solr™ 7.5.0 available

The Lucene PMC is pleased to announce the release of Apache Solr 7.5.0

Solr is the popular, blazing fast, open source NoSQL search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly scalable, providing fault tolerant distributed search and indexing, and powers the search and navigation features of many of the world's largest internet sites.

Solr 7.5.0 is available for immediate download at: http://lucene.apache.org/solr/downloads.html

See http://lucene.apache.org/solr/7_5_0/changes/Changes.html for a full list of details.

Solr 7.5.0 Release Highlights:

  • Nested/child documents may now be supplied as a field value instead of stand-off. Future releases will leverage this semantic information.
  • Enhance Autoscaling policy support to equally distribute replicas on the basis of arbitrary properties. Ranges and percentages can now be used in some policy rule declarations.
  • Nodes are now visible inside a view of the Admin UI "Cloud" tab, listing nodes and key metrics.
  • The status of zookeeper ensemble is now accessible under the Admin UI Cloud tab.
  • The new Korean morphological analyzer ("nori") has been added to default distribution.

You are encouraged to thoroughly read the "Upgrade Notes" at http://lucene.apache.org/solr/7_5_0/changes/Changes.html or in the CHANGES.txt file accompanying the release.

Solr 7.5 also includes many other new features as well as numerous optimizations and bugfixes of the corresponding Apache Lucene release.
