Write a MongoDB query to find the restaurant Id, name, and grades for those restaurants which achieved a grade of "A" and scored 11 on an ISODate "2014-08-11T00:00:00Z" among many of survey dates.

Structure of 'restaurants' collection :

{
  "address": {
     "building": "1007",
     "coord": [ -73.856077, 40.848447 ],
     "street": "Morris Park Ave",
     "zipcode": "10462"
  },
  "borough": "Bronx",
  "cuisine": "Bakery",
  "grades": [
     { "date": { "$date": 1393804800000 }, "grade": "A", "score": 2 },
     { "date": { "$date": 1378857600000 }, "grade": "A", "score": 6 },
     { "date": { "$date": 1358985600000 }, "grade": "A", "score": 10 },

  ],
  "name": "Morris Park Bake Shop",
  "restaurant_id": "30075445"
}

Query:

db.restaurants.find( 
                {
                 "grades.date": ISODate("2014-08-11T00:00:00Z"), 
                 "grades.grade":"A" , 
                 "grades.score" : 11

                {"restaurant_id" : 1,"name":1,"grades":1}
             );

Output:

Explanation:

The said query in MongoDB that searches for restaurants that received an "A" grade with a score of 11 on August 11th, 2014. The result documents will only include the "restaurant_id", "name", and "grades" fields.
The search criteria will match documents where the "grades" field contains an array of subdocuments, where at least one subdocument has a "date" field that matches the ISODate "2014-08-11T00:00:00Z".
The same subdocument also has a "grade" field that equals "A" and also has a "score" field that equals 11.
