Hi Alexey,

The e-commerce doesn't support a database. It's written in pure javascript and uses cookies to store the products in the user's cart.

If you need to use a custom DB to store your e-commerce data, you should use a custom code (created by third parties or by you).

Good afternoon.

I already guessed. I have still a question, on what algorithm search works? It is necessary for me, what it would ignore "-" and gaps?, and as possibility of use of the AND and OR functions is necessary

The search engine looks for the searched keywords in each page of the site. It just looks for the single words so no "AND", "OR" or other filters are actually supported.

It separates the keywords using the space character " ", so using "-" or "," it's different.
