ZREVRANGEBYLEX

ZREVRANGEBYLEX key max min [LIMIT offset count]

Available since 2.8.9.

Time complexity: O(log(N)+M) with N being the number of elements in the sorted set and M the number of elements being returned. If M is constant (e.g. always asking for the first 10 elements with LIMIT), you can consider it O(log(N)).

When all the elements in a sorted set are inserted with the same score, in order to force lexicographical ordering, this command returns all the elements in the sorted set at key with a value between max and min.

Apart from the reversed ordering, ZREVRANGEBYLEX is similar to ZRANGEBYLEX.

Return value

Array reply: list of elements in the specified score range.
