Just use [the delete index API](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-delete-index.html) if you want to remove everything.

You can do this using [delete by query](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/docs-delete-by-query.html), which results in all documents being deleted individually. This can be quite slow and expensive and simply deleting and recreating the index is much more fast and efficient.
