Yes, this is my opinion

"move to close", do you mean we should close this? Is indexNullAs good enough to replace this?

This is actually resolved by indexNullAs. Move to close
https://issues.apache.org/jira/browse/LUCENE-3593 adds a new filter for Lucene 3.6 that allows you to match documents that contain or do not contain a certain field.
This would be a usefull way to test for indexedEmbedded objects that are null in the query dsl. Something like
QueryBuilder qb = fts.getSearchFactory().buildQueryBuilder().forEntity(MyEntity.class).get(); qb.exists().onField("myField").createQuery(); qb.exists().not().onField("myField").createQuery();
