Q:

sunion command in redis return wrong result

I have a key "726fa624_F_2001#1#N" which is bound to a Set,the Set contains "yahoo.com,google.com,facebook.com,twitter.com".
I have another key "726fa624_F_2000#1#N" which is bound to a Set,the Set contains "newstime.com,myspace.com,amazon.com".
Now when I execute "SUNION 726fa624_F_2001#1#N 726fa624_F_2000#1#N" command through redis-cli,I expect the result to be a Set which contains "yahoo.com,google.com,facebook.com,twitter.com,newstime.com,myspace.com,amazon.com",but the real result is "yahoo.com,google.com,facebook.com,twitter.com"
what is the problem with it.
Thanks for your help!
The CLI session is as follows:
127.0.0.1:6000> SMEMBERS 726fa624_F_2201#1#N
1) "vpgboh.com"
2) "vpfbkt.com"
3) "vpgboe.com"
127.0.0.1:6000> SMEMBERS 726fa624_F_2202#1#N
1) "vpgboo.com"
2) "126.com"
3) "vpgbos.com"
4) "vpgbor.com"
127.0.0.1:6000> SUNION 726fa624_F_2201#1#N 726fa624_F_2202#1#N
1) "vpgboh.com"
2) "vpfbkt.com"
3) "vpgboe.com"
