title: BookSleve Del redis key by wildcard
body: <p>I saw this example on removing Key from redis usign wildcard</p>
  
  <pre><code>You can delete multiple keys with just one DEL command
  
  DEL key1 key2 key3......
  
  
  You can also delete all keys matching an expression this way
  
  redis-cli KEYS "temp_cart:user*" | xargs redis-cli DEL
  </code></pre>
  
  <p>Let's say i have keys : key1a, key2b,key7a, .... and i would like to remove all that starts with key*</p>
  
  <blockquote>
    <p><strong>how do i tell booksleve to do that? when i pass string into its invalidate function with "keys*" it does not seem to do the trick.</strong></p>
