node.js - Filter data in redis -

i create record in redis using

var data = { 'userid': 'user1' ,  'message': 'test message' };    redisclient.hmset('messages:' + 1 , data);  var data1 = { 'userid': 'user2' ,  'message': 'test message' };    redisclient.hmset('messages:' + 2 , data1); 

i want data messages userid = user2.. how this.

you cannot filter directly. should using different keys userid:

var data1 = { "userid": "user1" ,  "message': "test message" };    redisclient.hmset("messages:" + data1.userid , data1.message);  var data2 = { "userid": "user2" ,  "message': "test message" };    redisclient.hmset("messages:" + data2.userid , data2.message); 

you can use

redisclient.hgetall("messages:user1") 

to messages user1.

if want partition timestamp (which not in original question), you'll have use sorted set instead of hash:

redisclient.zadd("messages:" + data1.userid, new date().gettime(), data1.message); 

use

redisclient.zrange("messages:" + data1.userid, 0, -1); 

to receive messages sorted timestamp.
