Question

programatically search products in magento 2. Please help me to get products using search criteria.

Answer 1

If you want to search Product programatically, try below code.

I used SKU to get Products.

Call this in your template file.

    #File: app/code/Pulsestorm/RepositoryTutorial/Command/Examples.php    

    //create our filter
    $filter_1 = $this->objectManager
    ->create('Magento\Framework\Api\FilterBuilder')
    ->setField('sku')
    ->setConditionType('like')
    ->setValue('WSH')    
    ->create();

    //add our filter(s) to a group
    $filter_group = $this->objectManager
    ->create('Magento\Framework\Api\Search\FilterGroupBuilder')
    ->addFilter($filter_1)
    ->create();

    // $filter_group->setData('filters', [$filter]);

    //add the group(s) to the search criteria object
    $search_criteria = $this->objectManager
    ->create('Magento\Framework\Api\SearchCriteriaBuilder')
    ->setFilterGroups([$filter_group])
    ->create();

    $productdata  = $this->objectManager->create('\Magento\Catalog\Model\ProductRepository')->getList($search_criteria)->getItems();  

        foreach ($productdata as $product) {
            echo  $product->getSKU();
        }
