Remove support for the default null token on index fields --------------------------------------------------------- Key: ISPN-12408 URL: https://issues.redhat.com/browse/ISPN-12408 Project: Infinispan Issue Type: Task Components: Embedded Querying, Remote Querying Reporter: Yoann Rodière Assignee: Yoann Rodière Priority: Major Fix For: 12.0.0.Dev05 The default null token isn't supported anymore in Hibernate Search 6. Each field that takes advantage of the {{indexNullAs}} feature should define the null token explicitly. The {{indexNullAs}} feature was deprecated in Infinispan 11: https://infinispan.org/docs/11.0.x/titles/upgrading/upgrading.html#entity... Also, Hibernate Search 6 offers an {{exist}} predicate, which is used in Ickle for {{IS NOT NULL}} conditions; so {{indexNullAs}} is no longer as important as before.
