How to search in redis for hash keys?

Question

I\'m using hash keys to store user details like:

 hmset user:1 user_name lee  age 21
 hmset user:2 user_name david  age 25
 hmset user:3 user_name chris  age 25
         


        

Answer 1

Acually You can do it with put values in key

HMSET lee:25 user_name lee age 25
HMSET massi:43 user_name massi age 43
HMSET lee:24 user_name lee age 24
HMSET lee:28 user_name lee age 28 city Berlin

Now you can find them with "keys" command

127.0.0.1:6379> keys *:25
1) "lee:25"
127.0.0.1:6379> keys lee*
1) "lee:25"
2) "lee:24"
3) "lee:28"
127.0.0.1:6379> keys massi:43
1) "massi:43"

Finally find specific hashes

127.0.0.1:6379> HGETALL lee:24
1) "user_name"
2) "lee"
3) "age"
4) "24"

All that I said is that you can do it in two steps put any number of values that you need in key then find them. But consider that it's not a good idea to put all values inside key Just put ones that you need to do filtering with. Cheers :)
