Find in dictionary by value in Mongo

Question

I have such structure in my Mongo db:

{'_id':'...', 
    'friends': 
        {'id1': {'name1':'value1', 'name2':'value2'},
        'id2': {'name1':'', 'name2':''},
         ...}
}

How can I find element(friend) in this dictionary(friends) by name1(value1)?

Answer 1

db.myCollection.find({"friends.id1.name1":"Sam"})
