Repository queries using exists might not return the correct number of documents.

Since Elasticsearch 8.4 there is a bug in Elasticsearch (see elastic/elasticsearch#89760) which can lead to Elasticsearch not returning the correct number of hits. This will then result incorrect results returned from repository methods that use exists like for example findByNameExists().

There is nothing Spring Data Elasticsearch can do but wait for the bug in Elasticsearch to be fixed.

Looking at elastic/elasticsearch#90341 this will be in branch 8.5, so need to keep this a little linger.
