# ZCOUNT












Returns the number of elements in the sorted set at `key` with a score between
`min` and `max`.

The `min` and `max` arguments have the same semantic as described for
[`ZRANGEBYSCORE`](https://redis.io/docs/latest/commands/zrangebyscore).

Note: the command has a complexity of just O(log(N)) because it uses elements ranks (see [`ZRANK`](https://redis.io/docs/latest/commands/zrank)) to get an idea of the range. Because of this there is no need to do a work proportional to the size of the range.

## Examples


ZADD myzset 1 "one"
ZADD myzset 2 "two"
ZADD myzset 3 "three"
ZCOUNT myzset -inf +inf
ZCOUNT myzset (1 3
