[mongoose] search documents that contains an array of objects with 2 or more keys on the basis of a single key

I want to search a document that contains an array of objects with 2 or more keys on the basis of a single key within the array of objects.
For example I have the following scema-
var empSchema = new Schema({
 name : String,
 age : Number,
 projects : [{id : Schema.Types.ObjectId, name : String}]

});
I want to search all emloyees who worked on project named "Sample Project".
Thanks in advance.

I think the query condition you want is:

{'projects.name': 'Sample Project'}

See relevant Mongo docs:
