Apache Solr 7.2.0 已发布，Apache Solr (读音: SOLer) 是一个开源的搜索服务器。Solr 使用 Java 语言开发，主要基于 HTTP 和 Apache Lucene 实现。
该版本亮点包括： 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.
