Description
I think you should add an example that groups on multiple fields in
https://docs.mongodb.com/manual/reference/operator/aggregation/group/
I ended up learning about this elsewhere, but the quality of those web pages was much lower than the quality of MongoDB docs, so I prefer to remain within the docs.
I wanted to do something like:
db.sales.aggregate( [ { $group: { _id: { v1,: "field1", v2: "field2" }, |
count: { $sum: 1 } } } ] ) |
