The deprecation article does not list classes/packages and
https://access.redhat.com/documentation/en-us/red_hat_data_grid/8.2/html-single/migrating_to_data_grid_8/index#query-82_api-migration
talks about the indexing stuff but not about the hibernate/lucene annotations like

org.hibernate.search.engine.backend.types.Projectable;
org.hibernate.search.mapper.pojo.mapping.definition.annotation.Indexed;
org.hibernate.search.mapper.pojo.mapping.definition.annotation.KeywordField;

This statement might be confusing as it sounds like you can still use it from an application:

"Data Grid 8.2 adds upgraded versions of the Hibernate and Apache Lucene libraries on which the Query API is based for better performance and improved functionality."
