How to retrieve elasticsearch Data from Java application

Janusz_Dalecki · December 21, 2012, 8:52am

Hi Everybody,
I am trying to use elasticsearch from Java. (I am running elasticsearch server locally on my laptop using java 6 in Windows 7 64 bits and the client under eclipse Indigo)
First of all I have followed the tutorial “ElasticSearch in 5 minutes” and I created a few indexed data as per tutorial. (e.i. http://localhost:9200/blog/post/1 (in particular “Dilbert Brown” item - using postman http://localhost:9200/blog/user/dilbert' '{ "name" : "Dilbert Brown" }').

I have checked that the record and it does exist – using again postman util.
Everything works fine from dos command prompt – as described by the tutorial
My question is: how do I retrieve it from elasticsearch using Java. I have tried this code?
Client client = new TransportClient().addTransportAddress(new InetSocketTransportAddress("localhost", 9200));
SearchResponse response = client.prepareSearch("mongoindex").setSearchType(
SearchType.DFS_QUERY_THEN_FETCH).setQuery(QueryBuilders.termQuery("name", "Dilbert Brown"))
.setFrom(0).setSize(60).setExplain(true).execute().actionGet();

  SearchHit[] docs = response.getHits().getHits();

From prepareSearch method I am getting:

org.elasticsearch.client.transport.NoNodeAvailableException: No node available
at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:205)

Hello!

The exception indicates that your client can't connect to the
Elasticsearch cluster. I see you are using 9200 port, try 9300 - it is
the port for communication using transport client.

Same thing. It actually works from Explore on port 9200 - that is way I was using 9200 in a first place.

Rafal_Kuc_3 · December 21, 2012, 10:06am

Hello!

The 9200 is used to communicate using HTTP API, the 9300 is used for
the communication using TransportClient which you are using in your
Java code.

I don't know if you've change the cluster name, but try something like
this:

TransportClient client = new TransportClient(ImmutableSettings.settingsBuilder().put("cluster.name", clusterName).build());
client.addTransportAddress(new InetSocketTransportAddress("localhost", 9300));

I also noticed you have the following code:

client.prepareSearch("mongoindex")

Do you have 'mongoindex' index created ?

Hi,
Thanks a lot Rafał for answering my question. I have just been asked to
evaluate some different nosql products for our work – in this field I am
the beginner – so thanks for your help. I am basically following the
tutorial to learn more about elasticsearch (“Elasticsearch in 5 minutes“ -
http://www.elasticsearchtutorial.com/elasticsearch-in-5-minutes.html). You
were right I did not specify proper index. If I follow the tutorial I
thought the index is “blog”, isn’t it? But when I specify index “blog” I
don’t get any results:

String clusterName = "elasticsearch";

  TransportClient client = *new* TransportClient(ImmutableSettings.*

settingsBuilder*().put(

      "cluster.name", clusterName).build());

  client.addTransportAddress(*new* InetSocketTransportAddress(

"localhost", 9300));

  SearchResponse response = client.prepareSearch("blog").setSearchType(

      SearchType.*DFS_QUERY_THEN_FETCH*).setQuery(

      QueryBuilders.*termQuery*("name", "Dilbert Brown"

)).setFrom(0).setSize(60).setExplain(true)

      .execute().actionGet();



  SearchHit[] docs = response.getHits().getHits();

  System.*out*.println("size is " + docs.length);
  client.close();   The size is 0. Obviously I do not understand

something. What am I doing wrong?

Janusz

A term query is not analyzed, while the name field is. Analyzing a field
means processing the value through the Lucene token filters and tokenizers.

Try using a match query or query string. Those queries will analyze the
search string.

Hello!

Try looking at the query DSL and a query type you are interested in - http://www.elasticsearch.org/guide/reference/query-dsl/

If you want your query to be analyzed try using match query http://www.elasticsearch.org/guide/reference/query-dsl/match-query.html

Hi Rafał,

Getting back to the "Elasticsearch in 5 minutes" -
http://www.elasticsearchtutorial.com/elasticsearch-in-5-minutes.html.

When they execute:

curl -XPUT 'http://localhost:9200/blog/post/1' -d '
{
"user": "dilbert",
"postDate": "2011-12-15",
"body": "Search is hard. Search should be easy." ,
"title": "On search"
}

It creates in the Elasticsearch db a record:

{

"_index": "blog",

"_type": "post",

"_id": "1",

"_version": 1,

"exists": true,

"_source": {

    "user": "dilbert",

    "postDate": "2011-12-15",

    "body": "Search is hard. Search should be easy.",

    "title": "On search"

}

}

I can't understand why the "blog" word from path becomes a "_index", the
"post" word becomes a "_type" and the "1" becomes a "_id". Is this
explained anywhere. I am not asking you to explain it all to me, but would
appreciate if you could refer me to a good tutorial that explains how the
url path components map to the record fields in the elasticsearch db. Also
Java examples would be great to look at.

Regards,

Janusz

Hi Rafał,
Getting back to the “Elasticsearch in 5 minutes“ - http://www.elasticsearchtutorial.com/elasticsearch-in-5-minutes.html.
When they execute:

curl -XPUT 'http://localhost:9200/blog/post/1' -d '
{
"user": "dilbert",
"postDate": "2011-12-15",
"body": "Search is hard. Search should be easy." ,
"title": "On search"
}

It creates in the Elasticsearch db a record:

{
"_index": "blog",
"_type": "post",
"_id": "1",
"_version": 1,
"exists": true,
"_source": {
"user": "dilbert",
"postDate": "2011-12-15",
"body": "Search is hard. Search should be easy.",
"title": "On search"
}
}
I can’t understand why the “blog” word from path becomes a “_index”, the “post” word becomes a “_type” and the “1” becomes a “_id”. Is this explained anywhere. I am not asking you to explain it all to me, but would appreciate if you could refer me to a good tutorial that explains how the url path components map to the record fields in the elasticsearch db. Also Java examples would be great to look at.
Regards,
Janusz

Janusz_Dalecki · December 25, 2012, 6:52am

I have previously asked a question about “Elasticsearch in 5 minutes”
example and why the code below does not return any result (it throws a NoNodeAvailableException
exception):

Client client = new TransportClient().addTransportAddress(new

InetSocketTransportAddress("localhost", 9200));

  SearchResponse response =

client.prepareSearch("mongoindex").setSearchType(

SearchType.DFS_QUERY_THEN_FETCH).setQuery(QueryBuilders.termQuery("name",

"Dilbert
Brown")).setFrom(0).setSize(60).setExplain(true).execute().actionGet();

  SearchHit[] docs = response.getHits().getHits();

Ivan has pointed out that a term query is not analyzed, while the name
field is.

I did use a matching query and it does work – however I still don’t
understand the term query.

When would a term query work in this example.

Can somebody explain this in details, please?

The analysis concepts of Elasticsearch comes directly from Lucene, so you
can learn more by reading up on Lucene.

When you define your mapping, you can set a field to be analyzed or
not_analyzed:

not_analyzed fields do not go through analysis, which means tokenization,
filtering and other text analysis. The values remain as is. The default is
for fields to be analyzed. The search string for term queries are not
analyzed, so they are only useful for searching against fields that are
not_analyzed. If you want to search against a field that was analyzed, you
need to use a query that will also analyze the search terms (using the same
analyzer preferably).

You can use the Analyze API to see the Analyzer in action:

The keyword analyzer is similar to not using any analyzer.

Cheers,

Ivan

Hi All,

How to search specific text using Elasticsearch in java

this is my code..

Settings settings = ImmutableSettings.

settingsBuilder()
.put("http.enabled", "false")
.put("transport.tcp.port", "9300-9400")
.put("discovery.zen.ping.multicast.enabled", "false")
.put("discovery.zen.ping.unicast.hosts", "localhost").build();
      Node node = 
NodeBuilder.nodeBuilder().client(true).settings(settings).clusterName("elasticsearch").node();
client = node.client();
    QueryBuilder queryBuilder = QueryBuilders.termQuery("userName", 
"SampleUser");
SearchRequestBuilder searchRequestBuilder =
client.prepareSearch("_river");
searchRequestBuilder.setTypes("dc_user_river");
searchRequestBuilder.setSearchType(SearchType.DFS_QUERY_AND_FETCH);
searchRequestBuilder.setQuery(queryBuilder);
searchRequestBuilder.setFrom(0).setSize(60).setExplain(true);
SearchResponse resp = searchRequestBuilder.execute().actionGet();
System.out.println(resp);
for (SearchHit hit : resp.getHits())
System.out.println("Hit ID: "+hit.getId());
node.close();

output :
{
"took" : 32,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" :
}
}

i am getting 0 records.. is there any thing missing..
