Hello,
How do I configure the above using Java API just before the below
statement is called ?
IndexResponse response = \_client.prepareIndex(obj.get\_srch\_index(),
obj.get\_srch\_name(),obj.get\_srch\_Id())
.setSource(sourceString)
.execute()
.actionGet();
System.out.println(response.id());

The number of shards and replicas are part of the source object you
pass in. I prefer to use CreateIndexRequests over using the
IndexRequestBuilder directly. The number of shards and replicas are
specified in the settings object that is passed into the
CreateIndexRequest.
Settings settings =
ImmutableSettings.settingsBuilder().put("number\_of\_shards",
shards).build();
client.admin().indices().create(createIndexRequest).actionGet();
Cheers,
Ivan
P.S. When using Java, you should follow the Java Style Guidelines.

Percival,
Here is another example that uses CreateIndexRequestBuilder that Ivan
mentioned:
client.admin().indices().prepareCreate("test")
.setSettings(ImmutableSettings.settingsBuilder().put("number\_of\_shards",
2).put("number\_of\_replicas", "0"))
.execute().actionGet();
By the way, you can learn a lot about using Java API by looking at the
integration tests of elasticsearch.

Thanks for demonstrating another way with the API. My example code is
actually incomplete since I did not show how to create the actual
request with the settings!
createIndexRequest = new CreateIndexRequest(indexName, settings);
