Magento 2: Filtering Product Collections with Service Contracts
Magento 2 uses service contracts to filter product collections efficiently. Instead of relying on deprecated methods like getCollection(), the recommended approach is to use ProductRepositoryInterface with SearchCriteriaBuilder. This method ensures better performance, cleaner code, and future compatibility.

Magento 2: Filtering Product Collections with Service Contracts
In Magento 2, filtering product collections using service contracts is the recommended approach. Service contracts define how different modules interact, ensuring consistent data exchange and promoting clean code architecture.
To filter products by specific criteria, such as SKUs starting with "24-MB," you can utilize the ProductRepositoryInterface in conjunction with SearchCriteriaBuilder. Here's how you can implement this:
<?php
namespace Vendor\Module\Model;
use Magento\Catalog\Api\ProductRepositoryInterface;
use Magento\Framework\Api\SearchCriteriaBuilder;
class ProductService
{
private $productRepository;
private $searchCriteriaBuilder;
public function __construct(
ProductRepositoryInterface $productRepository,
SearchCriteriaBuilder $searchCriteriaBuilder
) {
$this->productRepository = $productRepository;
$this->searchCriteriaBuilder = $searchCriteriaBuilder;
}
public function getFilteredProducts()
{
$skuPrefix = '24-MB';
$this->searchCriteriaBuilder->addFilter('sku', $skuPrefix . '%', 'like');
$searchCriteria = $this->searchCriteriaBuilder->create();
$productList = $this->productRepository->getList($searchCriteria);
$products = $productList->getItems();
$productNames = [];
foreach ($products as $product) {
$productNames[] = $product->getName();
}
return $productNames;
}
}
In this implementation:
SearchCriteriaBuilderadds a filter to select products whose SKUs start with "24-MB".ProductRepositoryInterfaceretrieves the list of products matching the criteria.- The method returns an array of product names that meet the filter condition.
This method aligns with Magento 2's best practices by leveraging service contracts for data operations, ensuring a modular and maintainable codebase.

FAQs
Why Should I Use Service Contracts for Filtering Product Collections in Magento 2?
Service contracts provide a structured way to interact with data, ensuring maintainability and reducing dependency on direct model calls.
What Is the Recommended Method for Filtering Products Using Service Contracts?
Magento 2 recommends using SearchCriteriaBuilder with ProductRepositoryInterface to apply filters efficiently.
How Do I Filter Products by SKU Using Service Contracts?
Use the addFilter() method in SearchCriteriaBuilder to filter products based on SKU.
$this->searchCriteriaBuilder->addFilter('sku', '24-MB%', 'like');
$products = $this->productRepository->getList($this->searchCriteriaBuilder->create())->getItems();
What Are the Benefits of Using Service Contracts for Filtering?
- Scalability: Ensures compatibility with future Magento updates.
- Modularity: Separates business logic from data access.
- Efficiency: Optimizes queries and improves performance.
What Happens If I Use Deprecated Methods Like getCollection()?
Deprecated methods like getCollection() are not recommended as they bypass service contracts, making the code harder to maintain.
How Can I Debug Filtering Issues in Magento 2?
Use Magento’s built-in logging and debugging tools to inspect query results and ensure correct filter application.
Where Can I Learn More About Magento 2 Service Contracts?
Refer to Magento’s official developer documentation and community forums for best practices and implementation details.
