Hi,

I am quite beginner in ElasticSearch and Groovy. I have to perform CRUD (Create,Retrieve,Update and Delete) operations in ElasticSearch using Groovy.I am using IntelliJ for Groovy. I have found few lines of codes but getting multiple issues in code.So,couldn't proceed further.  
Looking for the suggestions and help.  
Thanks.

import org.elasticsearch.client.transport.TransportClient  
import org.elasticsearch.action.search.SearchResponse  
import org.elasticsearch.action.ListenableActionFuture

TransportClient client = TransportClient.builder().settings(Settings.settingsBuilder {  
client.transport.sniff = true  
cluster.name = "clustername"  
}).build()

client.addTransportAddress( (new TransportAddress(InetAddress.getByName("localhost"), 9200) ))

String userId = "1"

ListenableActionFuture future = client.searchAsync {  
indices "index"  
types "type"  
source {  
query {  
match {  
\_id = userId  
}  
}  
}  
}  
SearchResponse response = future.actionGet()  
println response

Transport Client uses Transport Port (9300) and not the Rest Port (9200).

@dadoonet Thank you so much for the reply. I tried changing the port to 9300 but still not working. It gives the following error:  
Error (10,29) Groovyc:unable to resolve class TransportAddress.

Not sure how all that plays with Groovy. May be @pickypg knows?

If possible anyway, you should use the REST client instead.

While going through some documentation, i found Groovy Elasticsearch Client and tried few lines of code as well. It didn't work either. Could you suggest me something regarding it @pickypg? Thanks.
