how to make a custom search/filter in Easy Admin - Symfony 4
the problem is that the fields I want to search for: relation
search input should be one, and work like "AND" operator
Entity

class Product
{

    /**
     * @ORM\ManyToOne(targetEntity="App\Entity\Category", inversedBy="products")
     */
    private $category;

    /**
     * @ORM\ManyToOne(targetEntity="App\Entity\Category2", inversedBy="products2")
     */
    private $category2;

    public function getCategory(): ?Category
    {
        return $this->category;
    }

    public function setCategory(?Category $category): self
    {
        $this->category = $category;

        return $this;
