instead of the two types in one Index (although this can be done ). The following command lists the types contained in each Index. $ Curl: 'localhost: 9200/_ mapping? Pretty = true' As planned (https://www.elastic.co/blog/index-type-parent-child-join-now-future-in-elasticsearch), Elastic 6.x allows only one Type for each Index, and 7.x removes the Type completely. 3.

More instructions on the Java API can be found here the Guide transmits JSON to the RESTful API via HTTP Other languages can communicate with Elasticsearch's RESTful API via Port 9200. In fact, as you can see, you could even use the line command curl to communicate with Elasticsearch.The requests made to Elasticsearch are
