es2.x version of Javaapi usages

Some time ago to do user tag system, the use of es2.2 to store queries. It involves the use of ES for JAVAAPI. Here to share some of the functions used by silly onions.

The first is an ES connection fetch operation instance.

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.QueryBuilders;
Import Org.elasticsearch.search.aggregations.AggregationBuilders;

Import Org.elasticsearch.search.sort.SortOrder;
Import java.net.InetAddress;

Import java.net.UnknownHostException;
 /** * Created by CC on 2016/4/4. * * Public class Es_client {public static final String cluster_name = "razor_es";//instance name private static final Stri
    ng IP = "192.168.1.1";  private static final int PORT = 9300; Port//1. Set Cluster Name: Default is Elasticsearch, and set Client.transport.sniff to true to enable clients to sniff the entire cluster state, adding other machine IP in the cluster to the client//to ES2.0 effective priv
            ate static settings settings = settings. Settingsbuilder (). Put ("Cluster.name", Cluster_Name) . put ("Client.transport.sniff", true). BuilD ();


    Create a private object private static Transportclient client; Static {try {client = Transportclient.builder (). settings (Settings). Build (). ADDT
        Ransportaddress (New Inetsockettransportaddress (Inetaddress.getbyname (IP), PORT));
        catch (Unknownhostexception e) {e.printstacktrace ();
    }//Get instance public static Transportclient Gettransportclient () {return client;
 }

}

Then there are some function actions:
