Trying to index a SQL database for a eCommerce. It is divided by store where each store has it's own products. I'm trying to create a schema with the following structure.

```auto
{
    name: "store1",
    products: [{name: "product1", price: "1"},...]

}

```

The problem I'm having is that I haven't found a way to avoid duplicate products when storing them as nested objects. Is this possible or is this approach just wrong.
