UserLogin Search Criterion

The `UserLogin` Search Criterion searches for content based on the User ID.

## Arguments

- `value` - string(s) representing the User logins(s)
- (optional) `operator` - operator constant (IN, EQ, LIKE)

## Limitations

Only the `IN` and `EQ` operators are supported.

    </Filter>
</Query>
```
