Use seachwords when searching list

I have some lists of products that the users can search trough. One of the filters is a database field for each product called search words. The list should show products that contains the search words the user searches for. But it seems that it shows all products every time.
Is it not possible to have a search word property on products? For example, if the user searches for “Burger” will all results containing all letters in “Burger” show?
It´s filtered like this: search words contains search word input

Hello, how are you? If you have a product database (Name, price, description, photo, stock, etc.) and a keyword related to products… add a list and an input… which keyword it contains input … or that the product description contains input
