AWS documentdb documentation change

Service: documentdb · 2026-03-31 · Documentation low

File: documentdb/latest/developerguide/not.md

Summary

Added comprehensive documentation for the $not operator in Amazon DocumentDB, including syntax, parameters, MongoDB shell examples, and code examples in Node.js and Python with connection strings

Security assessment

The change adds documentation for a query operator ($not) with no evidence of addressing a specific security vulnerability. However, the code examples include security-relevant configuration: TLS encryption (tls=true) and CA certificate validation (tlsCAFile=global-bundle.pem) in connection strings, which demonstrates secure connection practices. The documentation also mentions index support improvements in planner version 2.0, which is a performance enhancement rather than a security fix.

+Example (MongoDB Shell)Code examples
+
+# $not
+
+The `$not` operator is used to negate the result of a given expression. It allows you to select documents where the specified condition does not match.
+
+Planner version 2.0 added index support for `$not {eq}` and `$not {in}`.
+
+**Parameters**
+
+  * `expression`: The expression to negate.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates how to use the `$not` operator to find documents where the `status` field is not equal to "active".
+
+**Create sample documents**
+    
+    
+    db.users.insertMany([
+      { name: "John", status: "active" },
+      { name: "Jane", status: "inactive" },
+      { name: "Bob", status: "pending" },
+      { name: "Alice", status: "active" }
+    ]);
+
+**Query example**
+    
+    
+    db.users.find({ status: { $not: { $eq: "active" } } });
+
+**Output**
+    
+    
+    [
+      {
+        _id: ObjectId('...'),
+        name: 'Jane',
+        status: 'inactive'
+      },
+      {
+        _id: ObjectId('...'),
+        name: 'Bob',
+        status: 'pending'
+      }
+    ]
+
+## Code examples
+
+To view a code example for using the `$not` command, choose the tab for the language that you want to use:
+
+Node.js
+    
+    
+    
+    const { MongoClient, Filters } = require('mongodb');
+    
+    async function main() {
+      const client = await MongoClient.connect('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false');
+      const db = client.db('test');
+      const collection = db.collection('users');
+    
+      const result = await collection.find({
+        status: { $not: { $eq: "active" } }
+      }).toArray();
+    
+      console.log(result);
+    
+      await client.close();
+    }
+    
+    main();
+
+Python
+    
+    
+    
+    from pymongo import MongoClient
+    from bson.son import SON
+    
+    client = MongoClient('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false')
+    db = client['test']
+    collection = db['users']
+    
+    result = collection.find({
+        "status": {"$not": {"$eq": "active"}}
+    })
+    
+    for doc in result:
+        print(doc)
+    
+    client.close()
