# UserLogin Criterion

The [`UserLogin` Search Criterion](https://doc.ibexa.co/en/latest/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Query-Criterion-UserLogin.html) 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

Solr search engine and Elasticsearch support IN and EQ operators only.

## Example

### PHP

```
$query->query = new Criterion\UserLogin(['johndoe']);
```

```
$query->query = new Criterion\UserLogin('adm*', Criterion\Operator::LIKE);
```
