sort

$sort

Sorts documents in ascending or descending order based on one or more fields for the next stage in the aggregation pipeline.

Syntax

{ "$sort": { "<field1>": "<sort order>", "<field2>": "<sort order>"} }

Consider the following points for your sort criteria:

• Enter 1 to sort in ascending order for that field's values
• Enter -1 to sort in descending order for that field's values
• If you pass multiple sort criteria, the first criterion is the primary sort, and the second criterion sorts fields that are equal by the first criterion.
