Your code not work might because the product collection loaded somewhere, during Toolbar repair collection, you should create a custom filter append to the Layered Navigation.

You might check the Layer resolver:

  • vendor/magento/module-catalog/Model/Layer.php:147
  • $this->prepareProductCollection($collection);


  • Based on your detail, you are using elasticsearch, thus, you have to customize the request from Magento post to the ElasticSearch and filter it from ElasticSearch instead of filter the product collection from Magento.
  • Product is showing according to the filter but layered navigation is not working according to custom filter after add filter in to the prepareProductCollection function

You have a problem with plugin as @Arun pointed in the comment.

This is core getProductionCollection function:

public function getProductCollection()
        if (isset($this->_productCollections[$this->getCurrentCategory()->getId()])) {
            $collection = $this->_productCollections[$this->getCurrentCategory()->getId()];
        } else {
            $collection = $this->collectionProvider->getCollection($this->getCurrentCategory());
            $this->_productCollections[$this->getCurrentCategory()->getId()] = $collection;

        return $collection;

As you can read, the collection is stored inside _productCollections property, so it could be used after creation for other purposes like counting products inside toolbar.

I suggest you to use around plugin on prepareProductCollection method, so you can change your collection there:


namespace Sunarc\ProductListPage\Plugin\Model;

class Layer

     * @param \Magento\Catalog\Model\Layer $subject
     * @param callable $proceed
     * @param Collection $collection
    public function aroundPrepareProductCollection(\Magento\Catalog\Model\Layer $subject, callable $proceed, $collection)
        $collection->addAttributeToFilter("name", ["like" => "D%"]);
        return $proceed($collection);

This plugin will add attribute filter by name starting with letter D to your collection.

  • I tried but not working. Product collection has been override but layered navigation product counts still not updating.

  • I've tested that on core 2.4.2 and it's working. Do you have any third party modules that changes that behaviour?
