Mongodb search in Document and subDocument through single query - database

Question

I have a document with an array sub-document
I need to search on document and sub-document through a single query
I need results only of the sub-document array data, passing the criteria
Sample Data [2 documents]
{
_id : ObjectId("512e28984815cbfcb21646a7"),
name: David,
list: [
{
sport: basketball,
score: 100
},
{
sport: cricket,
score: 30
}
{
sport: rugby,
score: 100
}
]
},
{
_id : ObjectId("879e28664815cbfcb21622g9"),
name: Shawn,
list: [
{
sport: basketball,
score: 100
},
{
sport: cricket,
score: 50
}
{
sport: rugby,
score: 20
}
]
}
Expected Result
List of games in which David's score is 100
Document query name = David
Sub-document query score = 100
Response: [basketball, rugby]
Query tried but getting NULL is result
findOne({name:'David', "list.score": 100})

Answer 1

You can use an aggregation pipeline.
For name use a simple $match
For the array use the $filter function
Would be this one:
db.collection.aggregate([
{ $match: { name: "David" } },
{
$set: {
list: {
$filter: {
input: "$list",
cond: {$eq: ["$$this.score", 100] }
}
}
}
}
])

Answer 2

to get the List of games in which David's score is 100 you shoud do :
const user = await User.findOne({name:'David'})
if (user){
const games = user.list.filter(el => el.score === 100)
console.log(games)
}

Answer 3

Use the elemMatch projection operator to limit the elements of the array:
await User.findOne({name:'David', 'list.score': 100}).select({list:{$elemMatch:{score:100}})
That example document doesn't seem to be showing quotation marks around the strings.
Note that {score:100} will only match if the value is numeric, i.e. it will not match {sport: "basketball", score:"100"}

Answer 4

Just a topup to the ACCEPTED ANSWER
that match and set aggregation code can be produced from MongoDB compass too
