Whenever i try to filter by a custom attribute (type = price) i get the error :

Exception #0 (Exception): Item (Magento\Catalog\Model\Product\Interceptor) with the same ID "871" already exists

I also have the SQl but im not that familier with SQL code. Can someone see an error here (it is a multisite)

SQL that caused this :SELECT `e`.*, `cat_index`.`position` AS `cat_index_position`, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price`, `stock_status_index`.`stock_status` AS `is_salable`, IF(at_name.value_id > 0, at_name.value, at_name_default.value) AS `name` FROM `eh_catalog_product_entity` AS `e`  INNER JOIN `eh_catalog_category_product_index` AS `cat_index` ON cat_index.product_id=e.entity_id AND cat_index.store_id=1 AND cat_index.visibility IN(2, 4) AND cat_index.category_id='20'  INNER JOIN `eh_catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = '19'  INNER JOIN `eh_catalog_product_index_eav_decimal` AS `adviced_price_idx` ON adviced_price_idx.entity_id = e.entity_id AND adviced_price_idx.attribute_id = '170' AND adviced_price_idx.store_id
= 1  LEFT JOIN `eh_cataloginventory_stock_status` AS `stock_status_index` ON e.entity_id = stock_status_index.product_id AND stock_status_index.website_id = 0 AND stock_status_index.stock_id
= 1  INNER JOIN `eh_search_tmp_5a1be69bc93529_67461608` AS `search_result` ON e.entity_id = search_result.entity_id  LEFT JOIN `eh_catalog_product_entity_varchar` AS `at_name_default` ON (`at_name_default`.`entity_id` = `e`.`entity_id`) AND (`at_name_default`.`attribute_id` = '73') AND `at_name_default`.`store_id` = 0  LEFT JOIN `eh_catalog_product_entity_varchar` AS `at_name` ON (`at_name`.`entity_id` = `e`.`entity_id`) AND (`at_name`.`attribute_id` = '73') AND (`at_name`.`store_id` = 1) WHERE (adviced_price_idx.value >= 0) AND (adviced_price_idx.value < 10) ORDER BY `name` ASC  LIMIT 9

Anyone any idea?

The problem is caused by duplicate entries in the decimal index table 'product_index_eav_decimal. Does anyone know how this gets generated?

code :

protected function _renderFiltersBefore()


        if ($this->queryText) {

        $priceRangeCalculation = $this->_scopeConfig->getValue(
        if ($priceRangeCalculation) {

        $searchCriteria = $this->searchCriteriaBuilder->create();

        try {
            $this->searchResult = $this->getSearch()->search($searchCriteria);
        } catch (\Exception $e) {
            throw new LocalizedException(__('Sorry, something went wrong. You can find out more in the error log.'));

        $temporaryStorage = $this->temporaryStorageFactory->create();
        $table            = $temporaryStorage->storeDocuments($this->searchResult->getItems());

                'search_result' => $table->getName(),
            'e.entity_id = search_result.' . TemporaryStorage::FIELD_ENTITY_ID,

        if ($this->order && 'relevance' === $this->order['field']) {
            $this->getSelect()->order('search_result.' . TemporaryStorage::FIELD_SCORE . ' ' . $this->order['dir']);


This is the result in the database : enter image description here

Remove one of the 2 child (so its a unique row) and there is no problem anymore

  • You have an duplicated product, if you can add distinct to your query ou grouped by entity_id – Mohamed El Mrabet Nov 27 '17 at 10:30
  • The query is generated by Magento itself since its their layered navigation. Its default. I have a new question that i will update in my queston – CompactCode Nov 27 '17 at 10:38

My problem solved using Group By in my bestsellers collection.

$collection = $this->_addProductAttributesAndPrices($collection);
$collection->getSelect()->join(['bestsellers' => $collection->getTable('sales_bestsellers_aggregated_yearly')],
                                    'e.entity_id = bestsellers.product_id AND bestsellers.store_id = '.$this->getStoreId(),
                        ->order('qty_ordered DESC');
            return $collection;
  • is that the part : getSelect()->group('e.entity_id')->limit(15);? – CompactCode Nov 28 '17 at 14:07
  • I accepted this but other problems occur now like invalid count of products and things like that. Maybe i'm placing it wrong – CompactCode Nov 28 '17 at 14:27
  • Thanks for accept. Can you please paste your query here? – P_U Nov 29 '17 at 5:21
  • the query is at the top. I now even have this issue when just loading a category page – CompactCode Nov 29 '17 at 13:53
  • the problem seems to be that a grouped product has multiple entries within eh_catalog_product_index_eav_decimal since the simple products attached to them each have a different price. – CompactCode Nov 29 '17 at 13:58
