How to add a new property to a selection from a database in Yii2?

Question

Yii

Hello, I added a new property to the model:

class Product extends \yii\db\ActiveRecord
{
    public $searchingBy;

I am now looking for a product:
$product = Product::findOne(1);
How to set the value of this property correctly, and push it into the object with the product?
Thanks in advance!

$product->searchingBy = 'some value';
