Behavior of Sort method in MongoDB
- In MongoDB, the
sort()
method is used to sort the results of a query in either ascending or descending order based on one or more fields. - The
sort()
method takes an object as an argument, where each field to sort by is a key and the value is either1
for ascending order or-1
for descending order.
Here’s a basic example of using the sort()
method:
db.collection.find().sort({ field1: 1, field2: -1 })
Explanation:
- In this example, the
find
()
method retrieves documents from the collection, and thesort()
method sorts the results first byfield1
in ascending order, and then byfield2
in descending order. - If the
sort()
method is not provided, MongoDB will return the documents in the order they are stored in the database, which is typically the order in which they were inserted. - It’s important to note that the
sort()
method can impact performance, especially when sorting large result sets. In such cases, it’s recommended to use indexes to improve the performance of sorting operations.
MongoDB – sort() Method
In MongoDB, the sort()

It allows users to arrange documents in either ascending (1) or descending (-1) order based on the values of one or more fields. In this article, We will learn about the MongoDB sort() method in detail by understanding the various examples and so on.
