Hi,
I have an autocomplete system in my application that works fine with ES.
It exposes all search results via REST service written in Java with Spring
MVC.
So I'm using TransportClient to fetch my data stored on my local machine
and
I'm running ES with this config :
index.number\_of\_shards: 1
index.number\_of\_replicas: 0
BUT what I'm not understanding is why each time the autocomplete service is
called,
(when someone type a letter)
there is a new node that is created with a new name ?
Is this the normal behavior of ES ?
Thx

Hello!
Do you reuse a single instance of TransportClient or create a new one with each call ?

So I'll try to reuse a single instance !
I'll let u know how it is.

Hello!
Do you have ElasticSearch running ? Try sending a single query to it to see if it responds.

My ES instance is running (0.19.10): I have done :
[http://localhost:9200/\_cluster/nodes/\_local](http://localhost:9200/_cluster/nodes/_local)
and I get this response :
{
- ok: true,
- cluster\_name: "elasticsearch",
- nodes:
{
- 7k5aeHwoSd6LHv2erbcJCg:
{
- name: "Marko, Cain",
- transport\_address: "inet[/10.0.2.113:9300]",
- hostname: "MOE005X",
- http\_address: "inet[/10.0.2.113:9200]"
}
}
}
Here is how I set my TransportClient :
private Client client; public ElasticSearchController() { super();
initESClient(); } public void initESClient(){ Settings settings =
ImmutableSettings.settingsBuilder() .put("client.transport.sniff", true) .
put("client.transport.ignore\_cluster\_name", true) .build(); client = new
TransportClient(settings).addTransportAddress(new InetSocketTransportAddress
(ES\_INET.getValue(), 9300)); }
Then I just call the client object in the others methods like this :
QueryBuilder qb = QueryBuilders.queryString("_" + term.toLowerCase() + "_")
.useDisMax(true)
.defaultOperator(QueryStringQueryBuilder.Operator.AND)
.field("firstname")
.field("lastname")
.field("zip")
.field("city");
SearchResponse response = client.prepareSearch("peopledb")
.setSearchType(SearchType.DFS\_QUERY\_THEN\_FETCH)
.setQuery(qb)
.setFrom(0)
.setSize(10)
.setExplain(true)
.execute()
.actionGet();
Maybe I have missed something ?

Hello!
Try running [http://localhost:9200/\_cluster/health](http://localhost:9200/_cluster/nodes/_local) and please share the result.
And one more thing - what is TransportClient saying when connecting to your cluster ?

Hello!
As you can see there is an error when TransportClient tries to connect to your cluster. Do you use 0.19.10 version of ES library in your application ?

Just in case you are using Spring, you can use the spring factories for Elasticsearch: [https://github.com/dadoonet/spring-elasticsearch](https://github.com/dadoonet/spring-elasticsearch)
It could help you to connect to your running node using a TransportClient.

Thanks David,
I have just discovered this today. Indeed I'm using Spring MVC 3.0.1
but is it possible use it with annotation ?

plus simple pour moi en Fr 😉 )

SORRY, it's possible !
Ok let me give it a try and I'll make a feedback here later.
Thx all !

There's no dedicated mailing list for the factory but there's a french elasticsearch user group where you can ask for help in french: [http://groups.google.com/group/elasticsearch-fr](http://groups.google.com/group/elasticsearch-fr)
That said, you can also send me direct mail to david (at) [pilato.fr](http://pilato.fr)
