elasticSearch5.X javaAPI rangeQuery分区间查询，最终用了一种最low的方法凑合？不知大神们有没有好解决方案？

import org.elasticsearch.action.search.SearchResponse;

import org.elasticsearch.client.transport.TransportClient;

import org.elasticsearch.common.settings.Settings;

import org.elasticsearch.common.transport.InetSocketTransportAddress;

import org.elasticsearch.index.query.QueryBuilder;

import static org.elasticsearch.index.query.QueryBuilders.*;

import org.elasticsearch.transport.client.PreBuiltTransportClient;



import java.net.InetAddress;

import java.net.UnknownHostException;



public class Main {

    public static void main(String[] args) {

        Settings settings = Settings.builder()

                .put("cluster.name", "test")

                .put("processors", 2)

                        .put("client.transport.sniff", true).build();



        TransportClient client = new PreBuiltTransportClient(settings);



        long stime = System.currentTimeMillis();

        try {

            client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9300));

        } catch (UnknownHostException e) {

          e.printStackTrace();

        }

        long etime=System.currentTimeMillis();

        System.out.println("client instantiated in "+(etime-stime)+"ms");





        // execute a search

        QueryBuilder qb = boolQuery()

                .should(rangeQuery("age").from("20").to("30"))

                .should(rangeQuery("age").from("40").to("50"));

        SearchResponse response = client.prepareSearch("twitter")

                .setTypes("tweet")

                .setQuery(qb)

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

                .get();



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

    }

}
