UserMetadata Search Criterion

The `UserMetadata` Search Criterion searches for content based on its creator or modifier.

## Arguments

- `target` - UserMetadata constant (OWNER, GROUP, MODIFIER); GROUP means the user group of the content item's creator
- `operator` - Operator constant (EQ, IN)
- `value` - int(s) representing the User IDs or user group IDs (in case of the UserMetadata::GROUP target)

## Example

**XML**

```xml
<Query>
    <Filter>
        <UserMetadataCriterion>
            <target>GROUP</target>
            <operator>EQ</operator>
            <value>12</value>
        </UserMetadataCriterion>
    </Filter>
</Query>
```

**JSON**

```json
{
    "Query": {
        "Filter": {
            "UserMetadataCriterion": {
                "target": "GROUP",
                "operator": "EQ",
                "value": 12
            }
        }
    }
}
```

## Use case

You can use the `UserMetadata` Criterion to search for blog posts created by a specific user group, such as Contributor, by using the `GROUP` target with the `EQ` operator.
