Search filters don´t run simultaneously

-- HikaShop version -- : 2.6.0.

Hello!
I Am new in hikashop and have several doubts. I have installed hikashop and hikamarket and I am trying to configurate different filters for my shop.
After I had read the documentation of both plugins and I had read in the forum, I have not met the solution.
I imagine that I must be something doing wrong, but do not know what.

I explain it:
I need that different filters of search run "simultaneously " to specify better the product: Shop/vendor, kind of product, brand... that can be visualized in the "Catalago" menu or "Product Listing.

I had done:
1. I created a filter for every category or personalized fields,
2.Later, I created a module in joomla of "hikashop filter " and it to associate to Product Listing's menu in Hikashop Joomla's hidden menu.

The results are not the awaited ones because:
1. Whenever I search for a filter I annul my previous filters.
2. The search is not realized for I filter correctly.

Please, that I must do?
If you need more information, you question without problems
Thank you in advance.

Ok, Thanks.

Regards!
