Hello, We just published Hibernate Search 6.0.0.Alpha7, a new release of the still-in-development 6.0 branch. This release mainly restores missing parameters for index field types, restores explicit indexing APIs, and upgrades to Elasticsearch 6.8 and 7.1. As an Alpha, this version is an early technology preview. Be sure to read about it on our blog before you try it out: https://in.relation.to/2019/06/24/hibernate-search-6-0-0-Alpha7/ Yoann Rodière Hibernate NoORM Team yoann(a)hibernate.org
