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.

As per Redis 6.2.0, this command is considered deprecated. Please prefer using the ZRANGE command with the BYLEX and REV arguments in new code.

Return value

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