ElasticSearch Java api-5.x Delete and update index data

Version background:

<Dependency><groupId>Org.elasticsearch.client</groupId><Artifactid>Transport</Artifactid><version>5.4.1</version></Dependency>

First get the connection of es:

// Set cluster name        privatestaticfinal   Settings Settings = Settings.builder (). Put ("Cluster.name", "my-application"). Build (); // Cluster Name           // Create client       Private Static Final      Client  New  prebuilttransportclient (Settings)                            . addtransportaddress (New inetsockettransportaddress (Inetaddress.getbyname ("127.0.0.1"), 9300));  

Create indexes and establish mappings

 PublicString Create (map<string, object>map) {                indexresponse Response=client. Prepareindex ("index", "type", "PRIMARY key ID"). SetSource (Xcontentfactory.jsonbuilder (). StartObject (). Fiel D ("Business Field 1", "Value of Business Field 1"). Field ("Business Field 2", "Value of Business field 2")  . EndObject ()). Execute (). Actionget ();         }                return"Success"; }

Delete, based on primary key ID

 Public String Deleteesinfo (map<string, object> Map) {                             =client.preparedelete ("index", "type",  "PRIMARY key ID" )                                  . Execute ()                                  . Actionget ();                       Result=deleteresponse.getresult (). toString ();                                                       return result;    }

But this is only based on the primary key delete, if the query to delete according to the condition? Previously, this delete by query function was removed in the 2.X version because the official thought it would cause some errors if you need to install the Delete-by-query plugin yourself. More than 5.0 versions, and select Return. to conditionally Delete

Boolquerybuilder QueryBuilder = querybuilders.boolquery ();          Querybuilder.must (Querybuilders.termquery ("business Field 1", "Value of Business Field 1");                       =                  DeleteByQueryAction.INSTANCE.newRequestBuilder (client)                      . Filter (QueryBuilder)                       . Source (" Index ")                                                        . get ();                                                                  Long

Then, according to the primary key to update the ES information, which does not appear in the field to update, do not overwrite the original value.

Updateresponse  response = ElasticsearchConfig.client.prepareUpdate ("index", "type", "PRIMARY Key ID")            . Setdoc ( Xcontentfactory.jsonbuilder ().                     startobject () field                    ("business Field 1", "2")                    . Field ("Business field 2", "1" )  .                    EndObject ()). Execute ()              . Actionget ();
