If you want use console indexing

• Attach component in your config file:

'components' => [
    'search' => [
        'class' => 'sadovojav\search\components\SearchLucene',

        'models' => [
            [
                'dataProviderOptions' => [
                    'query' => common\modules\news\models\News::find()
                        ->localized('en')
                        ->active()
                ],
                'attributes' => [
                    'lang' => 'en', // Custom fild to search
                    'name' => [
                        'name' => SearchLucene::FIELD_TEXT
                    ],
                    'text_intro' => [
                        'text_intro' => SearchLucene::FIELD_UN_STORED
                    ],
                    'text_full' => [
                        'text_full' => SearchLucene::FIELD_UN_STORED
                    ],
                ],
            ]
        ]
    ]
]

    'modules' => [
        'search' => 'sadovojav\search\Module'

        $query = html_entity_decode(trim($q));

        // Search documents without custom conditions
        // $results = Yii::$app->search->search($query);

        // Search documents with custom conditions (lang)
        $results = Yii::$app->search->search($query, [
            'lang' => Yii::$app->language
        ]);

        $dataProvider = new ArrayDataProvider([
            'allModels' => $results,
            'pagination' => [
                'defaultPageSize' => self::ITEMS_PER_PAGE,
                'forcePageParam' => false
            ]
        ]);

        return $this->render('index', [
