The $sort stage accepts a map of field names to sort order.

SortOrder enum can be:

• Ascending: 1
• Descending: -1
• TextScore (TBD)
• Various other meta operators

The method signature should be:

function sort(SortOrder|int ...$fields)

Usage:

Stage::sort(created_at: SortOrder::Ascending);

Stage::sort(... ['tags.id' => SortOrder::Descending]);

Implement the Text Score Metadata Sort Example.

Sort specifications are also used by:

• $bottom
• $bottomN
• $sortArray
• $top
• $topN
• $fill

• $setWindowFields
