Filter by attributes with AND logic instead of OR

Hi,

I realized that when filtering products by selecting many attributes then the result shows products that include at least one of the selected attributes.
It would be nice the module "Eshop Advanced Search" to have an option to show products that include all the attributes.

At the moment I found a solution by changing only one line of code.
(I write the solution this way because the protection of the website does not allow SQL queries.)

In the file "components\com_eshop\models\search.php", go to line 239 that ends with code:
...IN (' . implode(',', $attributeIdsArr) . ')');
Make this line ending like the following:
...IN (' . implode(',', $attributeIdsArr) . ') GROUP BY pa.product_id HAVING COUNT(DISTINCT pa.attribute_id) = '.count($attributeIdsArr));

Hello Impression,

In the early of New Year 2017, we will release EShop Filter Products which will replace EShop Advanced Search module. Please wait until that to use EShop Filter Products.

It's coming...

Sincerely, Giang
