# LanguageCode Criterion

The [`LanguageCode` Search Criterion](https://doc.ibexa.co/en/latest/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Query-Criterion-Location.html) searches for content based on whether it's translated into the selected language.

## Arguments

- `value` - string(s) representing the language codes to search for
- (optional) `matchAlwaysAvailable` - bool representing whether content with the `alwaysAvailable` flag should be returned even if it doesn't contain the selected language (default `true`)

## Example

### PHP

```
$query->query = new Criterion\LanguageCode('ger-DE', false);
```

### REST API

**XML**

```
<Query>
    <Filter>
        <LanguageCodeCriterion>eng-GB</LanguageCodeCriterion>
    </Filter>
</Query>
```

**JSON**

```
"Query": {
    "Filter": {
        "LanguageCodeCriterion": "eng-GB"
    }
}
```

## Use case

You can use the `LanguageCode` Criterion to search for articles that are lacking a translation into a specific language:

```
$query = new LocationQuery;
$query->query = new Criterion\LogicalAnd([
    new Criterion\ContentTypeIdentifier('article'),
    new Criterion\LogicalNot(
        new Criterion\LanguageCode('ger-DE', false)
    )
    ]
);

$results = $this->searchService->findContent($query);
$articles = [];
foreach ($results->searchHits as $searchHit) {
    $articles[] = $searchHit;
}

return $this->render('list/articles_to_translate.html.twig', [
    'articles' => $articles,
]);
```
