AWS documentdb documentation change

Service: documentdb · 2026-03-28 · Documentation low

File: documentdb/latest/developerguide/regexFind.md

Summary

Entire documentation page for the $regexFind operator has been removed, including all examples, usage instructions, and code samples

Security assessment

The change removes documentation for a specific MongoDB operator ($regexFind) but provides no evidence of security vulnerabilities, patches, or security-related fixes. This appears to be routine documentation cleanup or restructuring, possibly due to feature deprecation or documentation reorganization. No security implications are mentioned in the removed content.

-# $regexFind
-
-New from version 5.0.
-
-Not supported by Elastic cluster.
-
-The `$regexFind` operator in Amazon DocumentDB is used to perform regular expression matching on string fields within documents. It allows you to search for and extract specific substrings that match a given regular expression pattern.
-
-**Parameters**
-
-  * `input`: The string field or expression to search.
-
-  * `regex`: The regular expression pattern to match.
-
-  * `options`: (optional) An object that specifies optional parameters for the regular expression, such as case-sensitivity and multi-line matching. Supported options are `i` (case-insensitive) and `m` (multi-line).

-
-## Example (MongoDB Shell)
-
-The following example demonstrates how to use the `$regexFind` operator to search for documents where the `name` field matches a specific regular expression pattern.
-
-**Create sample documents**
-    
-    
-    db.users.insertMany([
-      { "_id": 1, name: "John Doe", email: "[email protected]" },
-      { "_id": 2, name: "Diego Ramirez", email: "[email protected]" },
-      { "_id": 3, name: "Alejandro Rosalez", email: "[email protected]" },
-      { "_id": 4, name: "Shirley Rodriguez", email: "[email protected]" }
-    ]);
-
-**Query example**
-    
-    
-    db.users.aggregate([
-      {
-        $project: {
-          names: {
-            $regexFind: { input: '$name', regex: 'j', options: 'i' }
-          }
-        }
-      },
-      { $match: {names: {$ne: null}}}
-    ])
-
-This query will return all documents where the `name` field contains the letter "j" (case-insensitive).
-
-**Output**
-    
-    
-    [
-      { _id: 1, names: { match: 'J', idx: 0, captures: [] } }
-    ]
-
-**Note:** If your query is using Amazon DocumentDB planner version 1, you must use a hint to utilize an index. Without a hint, the query may perform a collection scan. To check your planner version and learn more about using hints, see the [Amazon DocumentDB Query Planner documentation](https://docs.aws.amazon.com/documentdb/latest/developerguide/query-planner.html).
