Enum SortMode

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<SortMode>, java.lang.constant.Constable, Writeable

    public enum SortMode
    extends java.lang.Enum<SortMode>
    implements Writeable
    Elasticsearch supports sorting by array or multi-valued fields. The SortMode option controls what array value is picked for sorting the document it belongs to. The mode option can have the following values:
    • 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.
