[Elasticsearch] JSON 스트링으로 질의요청

예전에도 JSON 스트링을 가지고 setSource() 함수로 질의 했었는데요.

필요하신 분들이 계신것 같아 쉬운 샘플 코드 올려 봅니다.

[Source Code]

package org.elasticsearch.action.search;

import org.elasticsearch.client.Client;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.index.query.TermQueryBuilder;
import org.elasticsearch.search.builder.SearchSourceBuilder;
import org.elasticsearch.transport.client.PreBuiltTransportClient;

public class HelloSearchSourceBuilder {

  public static void main (String[] args) {
    Client client;
    client = new PreBuiltTransportClient(Settings.EMPTY);

    SearchRequestBuilder searchRequestBuilder = client.prepareSearch();
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    TermQueryBuilder termQueryBuilder = QueryBuilders.termQuery("field1","value1");

    System.out.println(termQueryBuilder.toString());

    searchSourceBuilder.query(termQueryBuilder).from(0).size(10);

    System.out.println(searchSourceBuilder.toString());

    searchRequestBuilder.setSource(searchSourceBuilder);

    System.out.println(searchRequestBuilder.toString());
  }
}
