-# $set
-
-New from version 8.0
-
-Not supported by Elastic cluster.
-
-The `$set` aggregation stage in Amazon DocumentDB allows you to add new fields or update existing field values in documentation during an aggregation pipeline.
-
-**Parameters**
-
-  * `expression`: The expression to evaluate. This can be any valid aggregation expression, including field references and arithmetic operations.
-
-
-
-
-## Example (MongoDB Shell)
-
-The following example demonstrates the use of the `$set` aggregation stage to calculate totals by multiplying the `quantity` field by the `price` field.
-
-**Create sample documents**
-    
-    
-    db.inventory.insertMany([
-      { item: "pencil", quantity: 100, price: 0.24},
-      { item: "pen", quantity: 204, price: 1.78 }
-    ]);
-
-**Aggregation example**
-    
-    
-    db.inventory.aggregate([
-      {
-        $set: {
-          total: { $multiply: ["$quantity", "$price"] }
-        }
-      }
-    ])
-
-**Output**
-    
-    
-    [
-      {
-        _id: ObjectId('69248951d66dcae121d2950d'),
-        item: 'pencil',
-        quantity: 100,
-        price: 0.24,
-        total: 24
-      },
-      {
-        _id: ObjectId('69248951d66dcae121d2950e'),
-        item: 'pen',
-        quantity: 204,
-        price: 1.78,
-        total: 363.12
