Elasticsearch service [elasticsearch-service]

Elasticsearch service provides elasticsearch.client program API to communicate with Elasticsearch server HTTP API.

::::{note} The Elasticsearch service is only available server side. You can use the Data plugin. ::::

elasticsearch.client interacts with Elasticsearch service on behalf of:

• kibana_system user via elasticsearch.client.asInternalUser.* methods.
• a current end-user via elasticsearch.client.asCurrentUser.* methods. In this case Elasticsearch client should be given the current user credentials. See Scoped services and Security.

import { CoreStart, Plugin } from '@kbn/core/public';

export class MyPlugin implements Plugin {
  public start(core: CoreStart) {
    async function asyncTask() {
      const result = await core.elasticsearch.client.asInternalUser.ping(…);
    }
    asyncTask();
  }
}

For advanced use-cases, such as a search for specific objects, use the Global search plugin.
