- Usage:
-
ZREVRANGEBYSCORE key max min [ WITHSCORES ] [ LIMIT offset count ]
- 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)).
- Since:
- 2.2.0

- Array reply: a list of the members and, optionally, their scores in the specified score range.
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.
Examples
127.0.0.1:6379> ZADD myzset 1 "one"
(integer) 1
127.0.0.1:6379> ZADD myzset 2 "two"
(integer) 1
127.0.0.1:6379> ZADD myzset 3 "three"
(integer) 1
127.0.0.1:6379> ZREVRANGEBYSCORE myzset +inf -inf
1) "three"
2) "two"
3) "one"
127.0.0.1:6379> ZREVRANGEBYSCORE myzset 2 1
1) "two"
2) "one"
127.0.0.1:6379> ZREVRANGEBYSCORE myzset 2 (1
1) "two"
127.0.0.1:6379> ZREVRANGEBYSCORE myzset (2 (1
(empty array)
Deprecation advice
Instead of usingZREVRANGEBYSCORE use ZRANGE with the REV and BYSCORE arguments
