Search Module

-- url of the page with the problem -- : pymetal.tech-consulting.es
-- HikaShop version -- :2.2.
-- Joomla version -- : 3.2.1
-- PHP version -- : x.x.x
-- Browser(s) name and version -- : XXXXX x.x.x
-- Error-message(debug-mod must be tuned on) -- : Error_message

I have about 2400 categories.
I need a search module where I can find only products and categories and display like products and categories.
And another where I can find joomla articles.

I try with filters, without look. Only filter products in current category.

How I can do it?

Regards,

Jose
