[hibernate-dev] [Search] Deprecating @Boost and related options

Index time boosting is deprecated in Apache Lucene 6, and will be removed in Lucene 7. While we currently are using Lucene 5, since we'll likely jump directly to Lucene 7 with the next major version of Hibernate Search, I think we should prepare our users already. Let's deprecate @Boost and any option to control index-time boosting, so that people can start already to move to query-time boosting. - https://hibernate.atlassian.net/browse/HSEARCH-2735
