So I'm trying to build a csv export feature for discover on kibana 5.5.1, I'm trying to fetch all the data from elasticsearch on backend using

```
export default function (server) {
  server.route({
    config: {
      cors: {
        origin: ['*'],
      }
    },
    path: '/export',
    method: 'POST',
    handler: async (req, reply) => {
      const dataCluster = server.plugins.elasticsearch.getCluster('data');
      dataCluster.callWithRequest(req, 'search').then(res => {
        console.log(res);
      });
    }
  });

}

```

The thing is now I'm stuck on how to inject the request payload that kibana use in \_msearch REST API so that I can inject it to backend. Anyone ?

So if you see at the picutre, I want to get the **request payload** dynamically that kibana sent to \_msearch REST API from my custom plugin

</div>

how do you send the request to \_msearch to kibana inside your custom plugin ? do you use `SearchSource` ?

we don't have any documentation on that so i would suggest to look into the `SearchSource` source code (at `/src/ui/public/courier/data_source/`)

you can also take a look at this PR: where i am creating a new search source and then getting the response back: [https://github.com/elastic/kibana/pull/15525](https://github.com/elastic/kibana/pull/15525)

I hope this is helpful, regards, Peter
