Minor - P4 It's something like as $elemMatch projection works but instead returning the single value it could be return all matches like the follows:
{
_id: ObjectId(),
zipcode: 63109,
dependents: [
{ name: "john", school: 102, age: 10 },
{ name: "jess", school: 102, age: 11 },
{ name: "jeff", school: 108, age: 15 }
]
}
var projection = { _id: 0, dependents: { $filter: { school: 102 }}};
db.students.find( { zipcode: 63109 }, projection);
{
dependents: [
{ name: "john", school: 102, age: 10 },
{ name: "jess", school: 102, age: 11 }
]
}
