Summary

Removed entire documentation page for the $replaceOne operator in Amazon DocumentDB, including all content, examples, and code samples.

Security assessment

This change completely removes documentation for a specific MongoDB operator ($replaceOne) from the Amazon DocumentDB developer guide. There is no evidence in the diff that this removal is related to a security vulnerability, weakness, or incident. The removed content appears to be standard documentation for a string expression operator used in aggregation pipelines, with no security-related content mentioned. The removal could be part of routine documentation cleanup, reorganization, or deprecation of the feature, but without explicit security context, it cannot be classified as security-related.

-# $replaceOne
-
-Introduced in 5.0
-
-The `$replaceOne` operator in Amazon DocumentDB is a string expression operator used within aggregation pipelines to replace the first occurrence of a specified substring within a string with a replacement string. This operator is case-sensitive and only replaces the first match found.
-
-**Parameters**
-
-  * `input`: The string (field) on which to perform the find.
-
-  * `find`: The string to search for within the input.
-
-  * `replacement`: The string to replace the first occurrence of the find in the input(field).

-## Example (MongoDB Shell)
-
-The following example demonstrates how to use the `$replaceOne` operator within an aggregation pipeline to replace substrings in product names.
-
-**Create sample documents**
-    
-    
-    db.products.insertMany([
-      { "_id":1, "productId": "PROD-0Y9GL0", "name": "Gordon's Extra Creamy Milk Chocolate - Pack of 4", "category": "Confectionery", "price": 24.99 },
-      { "_id":2, "productId": "PROD-Y2E9H5", "name": "Nutrition Co. - Original Corn Flakes Cereal", "category": "Breakfast Cereals", "price": 8.50 },
-      { "_id":3, "productId": "PROD-Z3F8K2", "name": "Gordon's Dark Chocolate (90% Cocoa) Pack - Pack of 4", "category": "Confectionery", "price": 28.99 }
-    ]);
-    
-
-**Aggregation example**
-    
-    
-    db.products.aggregate([
-      {
-        $addFields: {
-          standardizedName: {
-            $replaceOne: {
-              input: "$name",
-              find: "Pack",
-              replacement: "Package"
-            }
-          }
-        }
-      }
-    ]);
-
-**Output**
-
-The output shows that only the first occurrence of "Pack" in each product name was replaced with "Package".
-    
-    
-    [
-      {
-        _id: 1,
-        productId: 'PROD-0Y9GL0',
-        name: "Gordon's Extra Creamy Milk Chocolate - Pack of 4",
-        category: 'Confectionery',
-        price: 24.99,
-        standardizedName: "Gordon's Extra Creamy Milk Chocolate - Package of 4"
-      },
-      {
-        _id: 2,
-        productId: 'PROD-Y2E9H5',
-        name: 'Nutrition Co. - Original Corn Flakes Cereal',
-        category: 'Breakfast Cereals',
-        price: 8.5,
-        standardizedName: 'Nutrition Co. - Original Corn Flakes Cereal'
-      },
-      {
-        _id: 3,
-        productId: 'PROD-Z3F8K2',
-        name: "Gordon's Dark Chocolate (90% Cocoa) Pack - Pack of 4",
-        category: 'Confectionery',
-        price: 28.99,
-        standardizedName: "Gordon's Dark Chocolate (90% Cocoa) Package - Pack of 4"
-      }
-
