ZREVRANGEBYSCORE key max min [WITHSCORES] [LIMIT offset count]

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)).

ACL categories: @read, @sortedset, @slow

Returns all the elements in the sorted set at key with a score between max and min (including elements with score equal to max or min). In contrary to the default ordering of sorted sets, for this command the elements are considered to be ordered from high to low scores.

The elements having the same score are returned in reverse lexicographical order.

Apart from the reversed ordering, ZREVRANGEBYSCORE is similar to ZRANGEBYSCORE.


Array reply: list of elements in the specified score range (optionally with their scores).
