title: How to use HSCAN command in Redis?
body: <p>I want to use Redis's HSCAN command in my assignment but I have no idea how it works. Redis's official page (<a href="http://redis.io/commands/hscan" rel="noreferrer">http://redis.io/commands/hscan</a>) for this command gives me blank page. </p>
  
  <p>I am getting continuous input data and saving them instantaneously in multiple hashes in Redis and I would like to iterate through all of them at later point of time. </p>
  
  <p>I'm using following command to save my data</p>
  
  <pre>
  HMSET myhash ordertype "neworder" order_ts "1234" act_type "order_ack" ack_ts "1240"
  HMSET myhash2 ordertype "neworder" order_ts "2234" act_type "order_ack" ack_ts "2240"
  </pre>
  
  <p>Can anyone give me some examples of how to use HSCAN? </p>
  
  <p>In my case I would like to get following output <br>
  1) myhash <br>
  2) myhash2 <br>
  3) myhash3 <br>
