Doctrine ORM SearchFilter

doctrine
API Platform provides a generic system to apply filters and sort criteria on collections. Useful filters for Doctrine ORM, MongoDB ODM and ElasticSearch are provided with the library. By default, all filters are disabled. They must be enabled explicitly.
// src/App/Entity.php
namespace App\Entity;
use ApiPlatform\Doctrine\Orm\Filter\SearchFilter;
use ApiPlatform\Metadata\ApiFilter;
use ApiPlatform\Metadata\ApiResource;
use Doctrine\ORM\Mapping as ORM;
#[ApiResource]
By using the #[ApiFilter] attribute, this attribute automatically declares the service, and you just have to use the filter class you want. If the filter is declared on the resource, you can specify on which properties it applies.
#[ApiFilter(SearchFilter::class, properties: ['title'])]
#[ORM\Entity]
class Book
{
    #[ORM\Id, ORM\Column, ORM\GeneratedValue]
    public ?int $id = null;
    #[ORM\Column]
    public ?string $title = null;
    #[ORM\Column]
We can also declare the filter attribute on a property and specify the strategy that should be used. For a list of availabe options head to the documentation
    #[ApiFilter(SearchFilter::class, strategy: 'partial')]
    public ?string $author = null;
}

// src/App/Playground.php
namespace App\Playground;
use Symfony\Component\HttpFoundation\Request;
function request(): Request
{
Try changing the search value in the interactive Playground.
    return Request::create('/books.jsonld?author=a', 'GET');
}

// src/DoctrineMigrations.php
namespace DoctrineMigrations;
use Doctrine\DBAL\Schema\Schema;
use Doctrine\Migrations\AbstractMigration;
final class Migration extends AbstractMigration
{
    public function up(Schema $schema): void
    {
        $this->addSql('CREATE TABLE book (id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, title VARCHAR(255) NOT NULL, author VARCHAR(255) NOT NULL)');
    }
}

// src/App/Fixtures.php
namespace App\Fixtures;
use App\Entity\Book;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Persistence\ObjectManager;
use function Zenstruck\Foundry\anonymous;
use function Zenstruck\Foundry\faker;
use function Zenstruck\Foundry\repository;
final class BookFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        $bookFactory = anonymous(Book::class);
        if (repository(Book::class)->count()) {
            return;
        }
        $bookFactory->many(10)->create(fn () => [
            'title' => faker()->name(),
            'author' => faker()->firstName(),
        ]
        );
    }
}

// src/App/Tests.php
namespace App\Tests;
use ApiPlatform\Playground\Test\TestGuideTrait;
use ApiPlatform\Symfony\Bundle\Test\ApiTestCase;
use App\Entity\Book;
final class BookTest extends ApiTestCase
{
    use TestGuideTrait;
    public function testAsAnonymousICanAccessTheDocumentation(): void
    {
        static::createClient()->request('GET', '/books.jsonld');
        $this->assertResponseIsSuccessful();
        $this->assertMatchesResourceCollectionJsonSchema(Book::class, '_api_/books{._format}_get_collection', 'jsonld');
        $this->assertJsonContains([

                        'property' => 'title',
                        'required' => false,
                    ],
                    [
