AWS documentdb documentation change

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

File: documentdb/latest/developerguide/nor.md

Summary

Added new documentation page for the $nor operator with MongoDB shell examples and code examples in Node.js and Python, including connection examples with TLS configuration.

Security assessment

The change adds documentation for a MongoDB query operator ($nor) with code examples that include TLS connection parameters (tls=true, tlsCAFile=global-bundle.pem). This demonstrates security best practices for encrypted connections but does not address a specific security vulnerability or incident.

+
+# $nor
+
+The `$nor` operator is used to match documents where none of the specified query conditions are true. It is similar to the logical "NOR" operation, where the result is true if none of the operands are true.
+
+**Parameters**
+
+  * `expression1`: The first expression to evaluate.
+
+  * `expression2`: The second expression to evaluate.
+
+  * `expressionN`: Additional expressions to evaluate.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates the usage of the `$nor` operator by retrieving documents where the `qty` field is not less than 20 and the `size` field is not equal to "XL".
+
+**Create sample documents**
+    
+    
+    db.items.insertMany([
+      { qty: 10, size: "M" },
+      { qty: 15, size: "XL" },
+      { qty: 25, size: "L" },
+      { qty: 30, size: "XL" }
+    ])
+
+**Query example**
+    
+    
+    db.items.find({
+      $nor: [
+        { qty: { $lt: 20 } },
+        { size: "XL" }
+      ]
+    })
+
+**Output**
+    
+    
+    [
+      { "_id" : ObjectId("..."), "qty" : 25, "size" : "L" }
+    ]
+
+## Code examples

+
+Node.js
+    
+    
+    
+    const { MongoClient } = require('mongodb');
+

+      const db = client.db('test');
+      const collection = db.collection('items');
+    
+      const result = await collection.find({
+        $nor: [
+          { qty: { $lt: 20 } },
+          { size: "XL" }
+        ]
+      }).toArray();
+    
+      console.log(result);
