redis sort by multi fields

It's easy to use sql to query with multi sort fields.For example:

select * from user order by score desc,name desc

with two fields sort(score,name).

how should do this in redis?

Use sorted set of redis which is sorted by score. You have to prepare score according to your needs.

finalScore = score*MAX_NAME_VALUE + getIntRepresentation(name) 
//MAX_NAME_VALUE is the maximum value returned by getIntRepresentation() method

and then use

 zadd myset finalScore value

and the just use

zrevrange myset 0 10
