Specifies a compound sort by providing one of more sorting expressions, ranking expressions, or both (together known as "ordering expressions"), in decreasing precedence. This node's value provides a binding to each result instance. All action inputs, in addition to the bound result, are in scope within the each block.

Example

...
  each (r) {
    sorting (r.price) {
      by (Desc)
      inverted
    }
    // compound in case of a tie
    ranking (-1 * r.price)
  }
