Multi match creates invalid query

This example:

bodybuilder()
        .query('multi_match', [ "info.name^3", "info.main_url^2" ], 'this is a test')
		.filter('term', 'user', 'kimchy')
        .build()

creates this query json:

{
  "query": {
    "bool": {
      "filter": {
        "term": {
          "user": "kimchy"
        }
      },
      "must": {
        "multi_match": {
          "info.name^3,info.main_url^2": "this is a test"
        }
      }
    }
  }
}

which is invalid query (tested with ES validate method ). I think problem is that multi_match expect ‘fields’ and ‘query’ argument and here it just creates query that is similar to normal match query.

The idea with bodybuilder v2 is that for complex queries like multi_match or query_string, you only specify an options object, like this:

bodybuilder()
  .query(
    'multi_match',
    {
      query: 'hello',
      fuzziness: 5,
      prefix_length: 0,
      fields: ['Field1^1000', 'Field2^3', 'Field3^2', 'Field4']
    }
  )
  .build()

Just ran into this - would be great to have this documented in the docs somewhere!
