Unique Constraints in Doctrine 2, Symfony 2

In the Table annotation, you can also set an index for multiple columns.

/**
 * @ORM\Entity
 * @ORM\Table(name="ecommerce_products",uniqueConstraints={
 *     @ORM\UniqueConstraint(name="search_idx", columns={"name", "email"})})
 */

or with YAML format:

Namespace\Entity\EntityName:
    type: entity
    table: ecommerce_products
    uniqueConstraints:
        uniqueConstraint:
            columns: [name, email]
