Missing filter for nested field not working

I am storing data in the following format:

{
"doc_id":"3434567778932";
"retweeted_user_profile":{
"name": "Henry",
"gender":"male"
}
}
I have mapped "retweeted_user_profile" as nested.

However the following query is not working

curl -XGET 'http://localhost:9200/twitter/_search' -d '{
"query" : {
"filtered" : {
"filter" : {
"missing" : { "field" : "retweeted_user_profile" }
}
}
}
}'

It is returning me all the results i.e it is also returning documents which
do not have field "retweeted_user_profile".
