MongoDB Aggregation $sort
Aggregation $sort
This aggregation stage groups sorts all documents in the specified sort order.
Remember that the order of your stages matters. Each stage only acts upon the documents that previous stages provide.
Example
In this example, we are using the "sample_airbnb" database loaded from our sample data in the Intro to Aggregations section.
db.listingsAndReviews.aggregate([
{
$sort: { "accommodates": -1 }
},
{
$project: {
"name": 1,
"accommodates": 1
}
},
{
$limit: 5
}
])
This will return the documents sorted in descending order by the accommodates field.
The sort order can be chosen by using 1
or -1.
1 is ascending and -1 is descending.
