Using POST body for search

[NathanHazout]

Using the simplest query:

client.search({q:"hello world})

I see from the network traffic that the request is POST but using URL query parameters: POST /_search?q=hello%20world HTTP/1.1. The request has no body.

Following the simple example in the documentation (https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/quick-start.html):

client.search({
  index: 'twitter',
  type: 'tweets',
  body: {
    query: {
      match: {
        body: 'elasticsearch'
      }
    }
  }
})

I see from the network traffic that it is making an OPTIONS request instead:
OPTIONS /twitter/tweets/_search HTTP/1.1

I am using the jQuery build (v10.1.3 - 2016-01-26)

I imagine what you are seeing is the preflight request sent by browsers for cross-domain requests.
