Discounts Algebra

To set qualifier and offers, update offer and qualifier attributes of discount when updating promotion.

You can have multiple qualifiers / offers in a single discount. They'll be joined using And rule.

Qualifier and offers, pointing to specific items, have search reference field, which can handle multiple references. If there are multiple references, at least one must match items from cart (inAnyOf rule).
