Hi Yoann Rodière, I did not set the schema management property, I was assuming the behaviour would be the same as the DirectoryBasedIndexManager, i.e. indexes created when the session factory boots up.

Probably there's a couple of issues here: the default schema management strategy is to not create the index, plus I also noticed the elastic search query targets both indexa, indexb when I explicitly created the query targeting TestEntity:

searchFactory.buildQueryBuilder().forEntity(TestEntity.class)

I will work on a reproducer
