/**
 * This function calculates the latest occurrence of the search field
 * (the first parameter), where sorting order is determined by the sort
 * field (the second parameter). This sorting order is always ascending
 * and null values always sort last. Both fields support null,
 * single-valued, and multi-valued input. If the latest sort field
 * value appears in multiple documents, this function is allowed to
 * return any corresponding search field value.
 *
 * @example
 *         @timestamp        |  name   | number
 * "2025-11-25T00:00:00.000Z | alpha   | 1"
 * "2025-11-25T00:00:01.000Z | alpha   | 2"
 * "2025-11-25T00:00:02.000Z | bravo   | null"
 * "2025-11-25T00:00:03.000Z | alpha   | 4"
 * "2025-11-25T00:00:04.000Z | bravo   | 5"
 * "2025-11-25T00:00:05.000Z | charlie | [6, 7, 8]"
 * "2025-11-25T00:00:06.000Z | delta   | null"
 *
 * From dataset
 * | STATS last_val = LAST(number, @timestamp) BY name
