How to search by products?

Question

Online shopping

I will say right away that I do not know php and mySQL, but I am good at typesetting and write a little in js. I have never done a search on the site, ie. This experience is my first. I would like to understand how easy and simple it is to make and implement on the site.
I really liked the search on this site: http://igryshki.by/catalog?search=carousel
That when you enter a few letters, the goods are already highlighted, this is very useful.
