21 December 2017, Apache Solr™ 7.2.0 available

The Lucene PMC is pleased to announce the release of Apache Solr 7.2.0

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 7.2.0 is available for immediate download at: http://lucene.apache.org/solr/mirrors-solr-latest-redir.html

See http://lucene.apache.org/solr/7_2_0/changes/Changes.html for a full list of details.

Solr 7.2.0 Release Highlights:

  • Bi-directional syncing of CDCR clusters is now supported.
  • The new synonymQueryStyle field type option allows for better scoring when terms at the same position are hyponyms/hypernyms rather than synonyms.
  • More stream evaluators, including: matrix operations; spline; derivative; regression; normalization; scaling; correlation; markov chains; time series differencing; and triangular and geometric distributions.
  • The new facet.matches parameter returns facet buckets only for terms that match a regular expression.
  • New Autoscaling features: the autoscaling/suggestions API end-point; the UTILIZENODE command, which moves replicas according to autoscaling policies and preferences; and the Autoscaling set-property command.

You are encouraged to thoroughly read the "Upgrade Notes" at http://lucene.apache.org/solr/7_2_0/changes/Changes.html or in the CHANGES.txt file accompanying the release.

Solr 7.2 also includes many other new features as well as numerous optimizations and bugfixes of the corresponding Apache Lucene release.
