### 1.score 是set排序的值，越大越在前
**添加 成员到sorted_set中，并设置score**

	ZADD key score member [score member ...]
	summary: Add one or more members to a sorted set, or update its score if it already exists
	since: 1.2.0

```redis
127.0.0.1:6379> zadd sset1 2 val4
(integer) 1
```



### 2. 查询sorted_set的成员数量

	ZCARD key 
	summary: Get the number of members in a sorted set
	since: 1.2.0

```redis
127.0.0.1:6379> ZCARD sset1
(integer) 5
```


### 3.获取score在min和max之间的数量


	ZCOUNT key min max
	summary: Count the members in a sorted set with scores within the given values
	since: 2.0.0

```redis
127.0.0.1:6379> ZCOUNT sset1 12 100
(integer) 2
127.0.0.1:6379> ZCOUNT sset1 0 200000
(integer) 5
```



### 4.增加sorted_set中成员的score


	ZINCRBY key increment member
	summary: Increment the score of a member in a sorted set
	since: 1.2.0

```redis
127.0.0.1:6379> ZINCRBY sset1 30 val1
"52"
```



### 5.将key1和key2...中重复的值得结果存到des-key中，numkeys为源key的数量


	ZINTERSTORE des-key numkeys key1 [key2 ...] [WEIGHTS weight] [AGGREGATE SUM|MIN|MAX]
	summary: Intersect multiple sorted sets and store the resulting sorted set in a new key
	since: 2.0.0

```redis
127.0.0.1:6379> ZINTERSTORE sset5 2 sset1 sset2
(integer) 3
```



### 6.获取sorted_set中index值在start和stop之间的值(包含首末值)


	ZRANGE key start stop [WITHSCORES]
	summary: Return a range of members in a sorted set, by index
	since: 1.2.0


### 7.获取sorted_set中index值在min 和max之间的值(包含首末值)


	ZRANGEBYSCORE key min max [WITHSCORES] [LIMIT offset count]
	summary: Return a range of members in a sorted set, by score
	since: 1.0.5

```redis
127.0.0.1:6379> ZRANGEBYSCORE sset5 6 11
1) "val4"
```



### 8.获取成员的索引位置


	ZRANK key member
	summary: Determine the index of a member in a sorted set
	since: 2.0.0

```redis
127.0.0.1:6379> ZRANK sset5 val3
(integer) 2
127.0.0.1:6379> ZRANGE sset5 0 10
1) "val4"
2) "val2"
3) "val3"
```



### 9.从sorted_set 中删除指定的成员（可多个）


	ZREM key member [member ...]
	summary: Remove one or more members from a sorted set
	since: 1.2.0


### 10.删除index值在start和stop之间的成员


	ZREMRANGEBYRANK key start stop
	summary: Remove all members in a sorted set within the given indexes
	since: 2.0.0


### 11.删除score值在min和max之间的成员


	ZREMRANGEBYSCORE key min max
	summary: Remove all members in a sorted set within the given scores
	since: 1.2.0


### 12.返回指定index在start和stop之间，并按score从高到底低排序


	ZREVRANGE key start stop [WITHSCORES]
	summary: Return a range of members in a sorted set, by index, with scores ordered from high to low
	since: 1.2.0

```redis
127.0.0.1:6379> ZREVRANGE sset5 0 2
1) "val3"
2) "val2"
3) "val4"
```

### 13.返回指定score在min和max之间，并按score从高到底低排序


	ZREVRANGEBYSCORE key max min [WITHSCORES] [LIMIT offset count]
	summary: Return a range of members in a sorted set, by score, with scores ordered from high to low
	since: 2.2.0


### 14.获取成员的索引位置，并按score从高到低排序


	ZREVRANK key member
	summary: Determine the index of a member in a sorted set, with scores ordered from high to low
	since: 2.0.0


### 15.获取指定成员的score


	ZSCORE key member
	summary: Get the score associated with the given member in a sorted set
	
	since: 1.2.0

```redis
127.0.0.1:6379> ZSCORE sset5 val2
"12"
```



### 16.连sorted_key显示结果，并将显示结果放到目标key中，numkeys代表源key的数目


	ZUNIONSTORE des-key numkeys key1 [key2 ...] [WEIGHTS weight] [AGGREGATE SUM|MIN|MAX]
	summary: Add multiple sorted sets and store the resulting sorted set in a new key
	since: 2.0.0
