How to correctly pass parameters to the search model?

Question

Yii

Here's the code I'm trying to find an element by id_group

$id = ($_GET['id']);
$searchModel = new CharacteristicGroupSearch();
$attributesModel = $searchModel->search(['id_group' => $id]);

Where should I put the parameters? searchModel, by the way generated by gii

Answer 1

and I entered it manually

$query = CharacteristicGroup::find()->where(['id_group' => $id]);
        $attributesModel = new ActiveDataProvider([
            'query' => $query
        ]);
