title: Wildcard search in cassandra database
body: <p>I want to know if there is any way to perform wildcard searches in cassandra database.
  e.g.</p>
  
  <pre><code>select KEY,username,password from User where username='\*hello*';
  </code></pre>
  
  <p>Or</p>
  
  <pre><code>select KEY,username,password from User where username='%hello%';
  </code></pre>
  
  <p>something like this.</p>
