7.16.2 client esClient.shutdown(); not working

• using docs: https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/connecting.html I get compile error

RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200)).build();

// Create the transport with a Jackson mapper
ElasticsearchTransport transport = new RestClientTransport(restClient, new JacksonJsonpMapper());
ElasticsearchClient esClient = new ElasticsearchClient(transport);

SearchResponse<Account> search = esClient.search(s
                -> s.index("account*")

}
esClient.shutdown();

I hit this issue today and I think that there’s something to do better. It’s a very weird Java API. For example, the ElasticsearchClient could implement Closeable interface and call the close on the outstanding restClient instance.

Please take your time to write up an easy to understand issue, in full sentences, including expectations (especially what you would expect), code samples that can be compiled locally (including imports and maybe even a proper test case sometimes).

Also, please do not mix up several issues, this makes it super hard to discuss, as github issues does not support threading.

The RestHighLevelClient is not part of this repo - this client however lead to the deprecation. What is your concrete question behind this? It is deprecated, this client is the successor.

The naming convention is correct, as this is how Elasticsearch is spelled.

Your last comment is without any context, please add some.

The term query only allows to search for a single term, take a look at the terms query or the bool query how to write several queries. Take a look at the different types of queries in the official Elasticsearch of the query DSL at https://www.elastic.co/guide/en/elasticsearch/reference/7.16/query-dsl.html

Also, the github issue tracker is for bugs, if you have questions about using the client, don’t hesitate to ask those in the discuss forum. Thanks a lot!
