Picture of products in search result

-- HikaShop version -- : latest
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.3.2.5
-- Browser(s) name and version -- : chrome

I did look for similar topics on this forum and found out, that there are 2 ways of implementing this:
1) to use hikashop filters intead of usual joomla search, right?
2) to use search plugins like Rokajaxsearch or Adsearch.

I`d like to use filters, but can`t understand, how to tie search button, positioned in module with filter feature of hikashop, so i`d be very gratefull for your help.
Picture below shows, where i`d like to leave searchbutton.

Actually, I already implemented it, so you can see it yourself.
Anyway, thx for reply.
