We have loaded product collection based on category ID, we are further trying to filter the product collection result with query string.

We have tried :

Query string set and get is working fine with below code.

$query = $this->_queryFactory->create();

Add search filter is not working to my product collection.

use Magento\CatalogSearch\Model\ResourceModel\Fulltext\Collection;


Can any one help me on this query.


addSearchFilter does not do much if you don't apply the filter:

public function addSearchFilter($query)
    $this->queryText = trim($this->queryText . ' ' . $query);
    return $this;

What you need to do is to inject \Magento\Framework\Api\FilterBuilder, \Magento\Framework\Api\Search\SearchCriteriaBuilder as well as \Magento\Search\Api\SearchInterface and do the following:

$searchCriteria = $this->searchCriteriaBuilder->create();
$this->searchResult = $this->searchInterface->search($searchCriteria);
  • if we join custom table and need to add that custom table column for search how to do it ? that is think there is custom table with FK product id and custom sku if customer search with custom sku the result should also display how to do it? – Pradeep Kumar Dec 6 '17 at 11:06
  • Getting error "Request name 'search' doesn't exist." at line $this->searchInterface->search($searchCriteria); – Magecode Apr 11 '19 at 6:44

It doesn't work how exactly?

The collection results do not change?

If the collection is loaded, than no amount of filtering will have effect on the results.

You would have to clear the collection and load it again:


Or add the filters before it gets loaded.

Is the collection returning no or incorrect results?

Have a look at the addSearchFilter function and check what is content of the queryText

public function addSearchFilter($query)
    $this->queryText = trim($this->queryText . ' ' . $query);
    return $this;

You can always look directly at the query and see if there are issues:
