Use built-in ajax hikashop for filter text

-- HikaShop version -- : 2.3.4.
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.3.29
-- Browser(s) name and version -- : comodo dragon

How you can use the built-in ajax hikashop in the "text" type filter?
At this time, type text in the filter does not meet modern requirements and is not effective. It is difficult to use the filter when it doesn't show the search results.
img1 - ajax search third-party
img2 - dropbox (filter hikashop)
img3 - text (filter hikashop)

How can I solve this problem?
How can I use ajax hikashop to search when typing appeared hints?
<input> <select>

Where the component you want to change?

Thanks in advance.
