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.
