Elasticsearch index mapping in java

Doru_Sular · February 4, 2014, 2:27pm

Hi guys,

I am trying to create an index with the following code:
XContentBuilder source = XContentFactory.jsonBuilder().startObject()//
.startObject("settings")
.field("number_of_shards", 1)
.endObject()// end settings
.startObject("mappings")
.startObject(INDEX_TYPE)//
.startObject("properties")//
.startObject("user")
.field("type", "string") // start user
.field("store", "yes")
.field("index", "analyzed")//
.endObject()// end user
.startObject("postDate")//
.field("type", "date")
.field("store", "yes")
.field("index", "analyzed")//
.endObject()// end post date
.startObject("message") //
.field("type", "string")
.field("store", "yes")
.field("index", "not_analyzed")
.endObject() // end user field
.endObject() // end properties
.endObject() // end index type
.endObject() // end mappings
.endObject(); // end the container object

    IndexResponse response = this.client.prepareIndex(INDEX, INDEX_TYPE

).setSource(source)
.setType(INDEX_TYPE).execute()
.actionGet();

I want to have the "message" field not analyzed, because later I want to
use facets to obtain unique messages.
Unfortunately my code seems to add just a document in index with the
following structure:
{
"settings": {
"number_of_shards": 1
},
"mappings": {
"tweet": {
"properties": {
"user": {
"type": "string",
"store": "yes",
"index": "analyzed"
},
"postDate": {
"type": "date",
"store": "yes",
"index": "analyzed"
},
"message": {
"type": "string",
"store": "yes",
"index": "not_analyzed"
}
}
}
}
}

Please help me to spot the error, it seems that mapping are not created.
Thank you very much,
Doru

The index request is used to index document, you should use put mapping
request.

e,g,
PutMappingResponse response =
client.admin().indices().preparePutMapping(INDEX).setType(INDEX_TYPE).setSource(source).get();

Hi, Kevin:

Create Index refhttp://www.elasticsearch.org/guide/en/elasticsearch/reference/current/indices-create-index.html#mappingssays mappings can be included in index settings JSON. Are you saying that's
not supported by the Java client? (Fwiw, I am seeing the same - just wanted
to confirm):
the following settings successfully create index with predefined mappings
when using curl put /idx -d @settings.json but not when fed to java client
like so:

    Settings settings =

ImmutableSettings.settingsBuilder().loadFromClasspath("es_admin_idx_settings.json").build();
return
getClient().admin().indices().prepareCreate(idxName).setSettings(settings).execute();

INFO metadata:114 - [Seth] [idx-elasticsearchserviceintegrationtest]
creating index, cause [api], shards [2]/[0], mappings //EMPTY MAPPINGS

{
"index" : {
"number_of_shards" : 1,
"number_of_replicas": 0
},
"mappings": {
"eligibility_criteria": {
"properties": {

"type" : "string",
"fields": {
"raw": {
"type" : "string",
"index": "not_analyzed"
}
}
}
}
}
}
}

prepareIndex() is to index a document. What you want is prepareCreate(). I
have an example here (check the method createIndexFullMapping()):

github.com

bly2k/es-java-examples/blob/master/admin/IndexAdminExample.java

package admin;

import org.elasticsearch.action.admin.indices.create.CreateIndexResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.common.settings.ImmutableSettings;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.xcontent.XContentBuilder;
import org.elasticsearch.common.xcontent.XContentFactory;

public class IndexAdminExample {
    public static void createIndex (Client client) {
        String index = "test";

        //delete index if exists
        if (client.admin().indices().prepareExists(index).execute().actionGet().isExists())
            client.admin().indices().prepareDelete(index).execute().actionGet();
        
        Settings settings = ImmutableSettings.settingsBuilder()
            .put("number_of_shards", 1)
            .put("number_of_replicas", 0)

fwiw, I fixed my issue below by using prepareCreate().setSource() - rather
than .setSettings() with idx config in the following format:

{"settings" : {
"index": {
"number_of_shards" : 1,
"number_of_replicas": 0,
"analysis" : {
"analyzer": {
"lowercase_keyword": {
"tokenizer": "keyword",
"filter" : ["lowercase"]
}
}
}
}
}, "mappings": {
"type1": {
"properties": {
"name": {
"type" : "string",
"index": "not_analyzed"
}
}
}
}}
