mongo equivalent of sql query - mongodb

Question

i need to build a mongo query to get results from a collection which has the same structure as the following sql.
click for picture of table structure
my sql query:
SELECT * FROM (
SELECT
db.date,
db.points,
db.type,
db.name,
db.rank,
YEARWEEK( db.date ) AS year_week
FROM _MyDatabase db
WHERE
db.personId = 100 AND
db.date BETWEEN '2012-10-01' AND '2015-09-30'
ORDER BY
YEARWEEK( db.date ),
db.type,
db.points DESC
) x
GROUP BY
x.year_week DESC,
x.type;
the result looks like this
date points type name rank year_week
-------------------------------------------------
23.10.2014 2000 1 Fish 2 201442
12.10.2014 2500 1 Fish 2 201441
16.10.2014 800 2 Fish 2 201441
i have tried different group / aggregate queries so far, but i couldn't get a similar result. hopefully one of you has more mongo experience than i and can give me a hint on how to solve this.

You would want something like this:
var start = new Date(2012, 9, 1),
end = new Date(2015, 8, 30),
pipeline = [
{
"$match": {
"personId": 100,
"date": { "$gte": start, "$lte": end }
}
},
{
"$project": {
"date": 1, "points": 1, "type": 1, "name": 1, "rank": 1,
"year_week": { "$week": "$date" }
}
},
{
"$sort": {
"year_week": 1,
"type": 1,
"points": -1
}
},
{
"$group": {
"_id": {
"year_week": "$year_week",
"type": "$type"
}
}
}
];
db.getCollection("_MyDatabase").aggregate(pipeline);
