How to handle multi dimensional objects

[yanosh-igor]

I have field in mongodb that contains json object. How can I save this document structure into elastic? Example:

in mongodb 
"location" : {
    "lon" : -71.715313,
    "lat" : 42.286992
  }

parse_method => "flatten" returns

 "location": "{"lon"=>-71.715313, "lat"=>42.286992}"

parse_method => "dig" returns

 "location": "{"lon"=>-71.715313, "lat"=>42.286992}"

parse_method => "simple" returns

  "location_lon": "-71.715313",
   "location_lat": "42.286992",

How can I leave same json structure?

"location" : {
    "lon" : -71.715313,
    "lat" : 42.286992
  }
