Search Results page showing all products without filtering the text

-- url of the page with the problem -- : uniqweb.my/demo/dreamztoy
-- HikaShop version -- : Business 3.4.1
-- Joomla version -- : joomla 3.8

Hi, is there anything others setting needed to make sure the filter work?
i Configured the module, filter, and menu that display all product listing.

but when i trying to search, all the products is coming out in search result page instead of filtered products.

Hi,

It looks fine.
You could try to not select any category in the filter, that might help.
Otherwise, updating your HikaShop might be the solution as we made many changes to the filters system since the 3.4.1 you're using.
