title: In Redis is it possible to find all hashes with a key containing a specified value?
body: <p>I am using Jedis, and new to both that and Redis itself.  I have db that stores hashes, and need to find all keys in the db that contain an entry with a specified key and a specified value.   EG: "find all hashes in the db that have key/value of STATUS=ERROR".   Is this possible in Jedis?  From what I can tell from googling, hscan will find keys in a specified hash.</p>
  
  <p>More generally, by way of teaching me to fish, any pointers for where to look this up?  It seems there is no real jedis api doc, and not even the Redis doc itself seems to have nothing on hscan.</p>
