Add search to custom query Yii2 - yii2

Question

I build a custom query to count and sum some of the field and then use gridview to display data.
Here is my query:
$query2 = (new \yii\db\Query())
->select([
'date',
'sum( IF(status = "Passed", 1, 0) ) AS passed',
'sum( IF(status = "Failed", 1, 0) ) AS failed',
'sum( IF(status = "On Hold", 1, 0) ) AS onhold',
'sum( IF(status <> "NULL", 1, 0) ) AS total'
])
->from('qa3d')->where(['week'=>$week])
->groupBy('date');
$dataProvider2 = new ActiveDataProvider([
'query' => $query2,
]);
And my gridview:
<?= GridView::widget([
'dataProvider' => $dataProvider2,
// 'filterModel' => $searchModel,
'headerRowOptions' => ['class' => 'kartik-sheet-style'],
'filterRowOptions' => ['class' => 'kartik-sheet-style'],
'panel' => [
'type' => GridView::TYPE_PRIMARY,
'heading' => 'Status Report by Analyst - Week to Date',
],
'toolbar' => [
'{toggleData}',
],
'pjax' => true,
'columns' => [
'date',
'passed',
'failed',
[
'attribute' => 'onhold',
'label' => "On Hold",
],
'total',
],
]); ?>
I commented out the filterModel because it's not working. How can I build a search like Gii CRUD generator did for this custom query?
Please help me with this.
Thank you!

Yes you have. You must create search form that point to action of that page then u must decide how will you forward params. You can put it to search model or get it and pass to query you have. IT depends where is your query.
$searchModel = new SomeSearchModel();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
or like this and then access array elements.
$post = Yii::$app->request->queryParams;
In your case I supposed you will search for $week = $post['week'];
