-# $regexMatch
-
-New from version 5.0. Not supported by Elastic cluster.
-
-The `$regexMatch` operator in Amazon DocumentDB is used to perform regular expression matching on string fields. It returns a boolean value (`true` or `false`) indicating whether the input string matches the specified pattern.
-
-**Parameters**
-
-  * `input`: The string to test against the regular expression.
-
-  * `regex`: The regular expression pattern to match.
-
-  * `options`: (Optional) Flags to modify the regular expression behavior, such as case-insensitive matching (`i`) or multiline matching (`m`).

-
-## Example (MongoDB Shell)
-
-The following example demonstrates how to use the `$regexMatch` operator to check if names start with the letter 'M'. The operator returns `true` or `false` for each document.
-
-**Create sample documents**
-    
-    
-    db.users.insertMany([
-      { "_id":1, name: "María García", email: "marí[email protected]" },
-      { "_id":2, name: "Arnav Desai", email: "[email protected]" },
-      { "_id":3, name: "Martha Rivera", email: "[email protected]" },
-      { "_id":4, name: "Richard Roe", email: "[email protected]" },
-    
-    ]);
-
-**Query example**
-    
-    
-    db.users.aggregate([
-      {
-        $project: {
-          name: 1,
-          startsWithM: {
-            $regexMatch: {
-              input: "$name",
-              regex: "^M",
-              options: "i"
-            }
-          }
-        }
-      }
-    ]);
-
-**Output**
-    
-    
-    { _id: 1, name: 'María García', startsWithM: true },
-    { _id: 2, name: 'Arnav Desai', startsWithM: false },
-    { _id: 3, name: 'Martha Rivera', startsWithM: true },
-    { _id: 4, name: 'Richard Roe', startsWithM: false }
