AWS documentdb documentation change

Summary

Added documentation for the $lt query operator with MongoDB shell examples and Node.js/Python code examples showing connection strings with TLS parameters

Security assessment

This change adds standard documentation for a MongoDB query operator ($lt) with code examples. The connection strings include TLS parameters (tls=true, tlsCAFile=global-bundle.pem) which are standard security practices for encrypted connections, but this is routine documentation of existing security features rather than addressing a specific security issue. No evidence of vulnerability remediation or security incident response.

+
+# $lt
+
+The `$lt` operator in Amazon DocumentDB is used to match values that are less than the specified value. This operator is useful for filtering and querying data based on numerical comparisons.
+
+**Parameters**
+
+  * `field`: The field name to check.
+
+  * `value`: The value to compare against.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates how to use the `$lt` operator to retrieve documents where the `Inventory.OnHand` value is less than 50.
+
+**Create sample documents**
+    
+    
+    db.example.insertMany([
+      { "_id": 1, "Inventory": { "OnHand": 25, "Sold": 60 }, "Colors": ["Red", "Blue"] },
+      { "_id": 2, "Inventory": { "OnHand": 75, "Sold": 40 }, "Colors": ["Red", "White"] },
+      { "_id": 3, "Inventory": { "OnHand": 10, "Sold": 85 }, "Colors": ["Red", "Green"] }
+    ]);
+
+**Query example**
+    
+    
+    db.example.find({ "Inventory.OnHand": { $lt: 50 } })
+
+**Output**
+    
+    
+    { "_id" : 1, "Inventory" : { "OnHand" : 25, "Sold" : 60 }, "Colors" : [ "Red", "Blue" ] }
+    { "_id" : 3, "Inventory" : { "OnHand" : 10, "Sold" : 85 }, "Colors" : [ "Red", "Green" ] }
+
+## Code examples
+
+To view a code example for using the `$lt` command, choose the tab for the language that you want to use:
+
+Node.js
+    
+    
+    
+    const { MongoClient } = require('mongodb');
+    
+    async function example() {
+      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('example');
+    
+      const result = await collection.find({ "Inventory.OnHand": { $lt: 50 } }).toArray();
+      console.log(result);
+    
+      await client.close();
+    }
+    
+    example();
+
+Python
+    
+    
+    
+    from pymongo import MongoClient
+    
+    def example():
+        client = MongoClient('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false')
+        db = client['test']
+        collection = db['example']
+    
+        result = list(collection.find({ "Inventory.OnHand": { "$lt": 50 } }))
+        print(result)
+    
+        client.close()
