What is the method for deleting multiple conditions in MongoDB?

In MongoDB, you can use the deleteMany() method to delete documents that meet multiple conditions. The specific steps are as follows:

1. Delete multiple documents from the collection.

db.collection.deleteMany(
   <filter>,
   {
     writeConcern: <document>,
     collation: <document>,
     hint:  <document|string>,
     limit: <boolean>,
     session: <session>
   }
)

Among them, is a document used to specify the conditions for deleting documents. For example:

db.users.deleteMany({ age: { $lt: 30 }, status: "active" })

The above example demonstrates deleting user documents with an age less than 30 and status as “active”.

1. After executing the above command, all documents that meet the conditions will be deleted. It is important to confirm the conditions are correct before carrying out the deletion in order to avoid accidentally deleting important data.
