  • min - Pick the lowest value.
  • max - Pick the highest value.
  • sum - Use the sum of all values as sort value. Only applicable for number based array fields.
  • avg - Use the average of all values as sort value. Only applicable for number based array fields.
  • median - Use the median of all values as sort value. Only applicable for number based array fields.
