redis:sorted_set类型

一.  
添加数据 ，score是排序依据
 zadd key score1 member1 [score2 member2] 
获取全部数据
 zrange key start stop [WITHSCORES] 
 zrevrange key start stop [WITHSCORES] 
删除数据
 zrem key member [member ...] 

按条件获取数据 
 zrangebyscore key min max [WITHSCORES] [LIMIT] 
 zrevrangebyscore key max min [WITHSCORES]
条件删除数据
 zremrangebyrank key start stop 
 zremrangebyscore key min ma

min与max用于限定搜索查询的条件 
start与stop用于限定查询范围，作用于索引，表示开始和结束索引 
offset与count用于限定查询范围，作用于查询结果，表示开始位置和数据总量

获取集合数据总量
 zcard key 
 zcount key min max 
集合交、并操作
 zinterstore destination numkeys key [key ...] 
 zunionstore destination numkeys key [key ...]

二.
获取数据对应的索引（排名）
 zrank key member 
 zrevrank key member
score值获取与修改 
 zscore key member 
 zincrby key increment member
