We're using Axios for request transactions and I guess that's not possible with Axios. see axios/axios#2400

And as mentioned in elasticSearch Request Body Search, we can use query parameters with GET request to send data as parameters. Kindly use Parameters section for that.

Well, we could implement it if needed. But it is not a supported behavior according to the HTTP spec. So we don't really want to support it in this app as well.

Here is the spec reference defining that https://tools.ietf.org/html/rfc7231#page-24
