Search Product by SKU programatically using search criteria

Question

I need to search product programatically using search_criteria

public function search($storeId, $searchTerm, $searchOrder, $searchDir, $page, $pageSize, &$totalSearchResults, &$attrs_applied, &$attrs_available)
{

 $search_criteria = $this->_searchCriteriaBuilder->create();

 $search_criteria->setRequestName("quick_search_container");


$firstCharacter = substr($searchTerm, 0, 1);


if($firstCharacter == ":") {


   $filter = $this->_filterBuilder->setField('sku')
        ->setValue(substr($searchTerm, 1))
        ->setConditionType("sku")
        ->create();


} else {

   $filter = $this->_filterBuilder->setField('search_term')
        ->setValue($searchTerm)
        ->setConditionType("like")
        ->create();
}

    $filterGroup = $this->_filterGroupBuilder->addFilter($filter)->create();

    $search_criteria->setFilterGroups([$filterGroup]);

    $resultx = $this->_SearchInterface->search($search_criteria);

    $totalSearchResults = $resultx->getTotalCount();

    $products = $resultx->getItems();

    return $products;

}

but no return results, and throw exception

Exception #0 (Magento\Framework\Search\Request\EmptyRequestDataException): The request query and filters aren't set. Verify the query and filters and try again.

any idea?
