I am new to Elastic search. I wanted to know that i am using java client to access ES. ``` Client client = new ``` TransportClient().addTransportAddress(new InetSocketTransportAddress("127.0.0.1", 9300)); Should i initiated client everytime i execute query or just once? If i start it just at the starting of application will i have to do something like refreshing client so that to get latest data? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I think you need to only initialize in once on application (JVM) launch. You can alternatively use the JAVA client API :- Node node = nodeBuilder().node(); Client client = node.client(); Refer :- > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

nodeBuilder or TransportClient both should be initialized once.right? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
